Long-term Vision

The Nippon Oil Group is aiming to achieve its basic strategy

of becoming an integrated energy company by the end of

fiscal 2010, ending March 31, 2011. Working to realize these

goals, we formulated our third medium-term consolidated

management plan, which positions the three-year period from

fiscal 2005 to fiscal 2007 as a time when we build a solid

foundation for our business. We are executing a range of ini-

tiatives to achieve the aims of the plan.

The Group’s operating environment is undergoing signifi-

cant change, including increasingly fierce international com-

petition for resources and declining demand for petroleum

products in Japan. Seeing this change as an opportunity, we

are aiming to build a business model capable of sustaining

growth while further enhancing corporate value.

Fiscal 2006 Results

In the fiscal year under review, the second year of the third

medium-term consolidated management plan, the Group

posted consolidated net sales of ¥6,624.3 billion, an increase

of 8.3% on the previous fiscal year. Consolidated ordinary

income fell ¥122.5 billion to ¥186.6 billion. This mainly

reflected the negative impact of the inventory valuation fac-

tor, which had significantly boosted ordinary income in the

previous fiscal year. Inventory valuation using the gross aver-

age method affects the cost of goods sold due to fluctuations

in crude oil prices. Excluding this factor, consolidated ordi-

nary income actually increased ¥53.1 billion year on year, to

¥195.8 billion. This was achieved because higher income from

the E&P and petrochemicals businesses, areas we are focus-

ing on in particular as a pillar of our growth strategy, more

than offset lower sales volumes for petroleum products caused

Based on its philosophy, “Creating the energy

future and promoting prosperity and harmony

with nature,” the Nippon Oil Group will make

sustained growth possible by becoming an

integrated energy company.

Making Sustained Growth Possible

by a record warm winter and the growing shift to different

types of fuels by end-users. ROE was down 10.1 percentage

points at 5.9%, or 0.2 percentage points lower at 6.4%

excluding the inventory valuation factor.

As part of the third medium-term consolidated manage-

ment plan, we reviewed the past level of dividends and set a

target for the annual dividend of ¥12 per share. Accordingly,

the dividend applicable to the fiscal year under review is

unchanged from the previous fiscal year at ¥12.

Toward Sustained Growth

In April 2006, we updated our philosophy, comprising the

Group philosophy, six values we respect and standards of

conduct. As a result, we created the new Group philoso-

phy: “Creating the energy future and promoting prosperity

and harmony with nature.” This emphasizes the concepts

of responsibility for the future of energy and achieving har-

mony with the global environment. Diligently applying this

philosophy in practice to steadily fulfill our responsibilities

to society will play a significant role in boosting the Group’s

corporate value.

In the upcoming final year of the third medium-term

management plan, and through the fourth medium-term

management plan that starts the following fiscal year, we

will work to achieve sustained growth by becoming an inte-

grated energy company.

Interview With the President

Please review the fiscal year just ended.I can summarize by saying that it was a year in which there were signs of ourstrategies paying off handsomely, although some major issues did emerge.With the third medium-term consolidated management plan, the Nippon Oil Group is aiming to real-

ize consolidated ordinary income of ¥190 billion, excluding inventory valuation factors, in fiscal 2007,

ending March 31, 2008. During the fiscal year under review, which marks the halfway point to this goal,

we recorded ordinary income of ¥186.6 billion, down ¥122.5 billion year on year. However, if inventory

valuation factors are excluded, ordinary income totaled ¥195.8 billion, up ¥53.1 billion year on year. I

believe this indicates that income levels are at healthy levels as we approach the March 2008 target.

In 1998, the year immediately before the merger of Nippon Oil and Mitsubishi Oil, the combination

of the two companies’ results amounted to an ordinary loss of ¥2.4 billion. Subsequently, in the period

from fiscal 1999 to fiscal 2003, ordinary income exclusive of inventory valuation factors remained at low

levels in the range of ¥33.3 billion to ¥62.9 billion. This period was one in which we had to show patience,

as we set about laying the foundations to realize the benefits of the merger and taking the first steps

toward growth. Specifically, we carried out brand and system integration in a short space of time, with no

major disruption, and also made rapid progress in combining our separate corporate cultures. For these

Setting the Stage for a New Phase of Growth

reasons, this integration is still cited in Japan as an exemplary merger. By fiscal 2003, we had completely

succeeded in establishing systems and a culture to strictly manage return on investments. This was made

possible through achieving a sound balance sheet by fully disposing of legacy negative assets, recognizing

an impairment loss of approximately ¥170 billion in the process. We also built a firm foothold for our

growth strategies by shifting management resources—personnel, assets and funds—into our E&P, Petro-

chemicals and new business such as LNG and fuel cells. From fiscal 2004 onwards, the benefits of long-

term initiatives and the complete establishment of post-merger internal systems, including those to manage

return on investment, began to feed through to the bottom line. During this period, ordinary income

exclusive of inventory valuation factors has been in the ¥142.7 billion to ¥195.8 billion range. While we still

do not believe this is adequate, we see it as a base from which to move on to the next level in responding

to the expectations of all our shareholders.

The fiscal year under review brought major changes in the external operating environment, includ-

ing high crude oil prices and a sharp drop in demand for petroleum products in Japan. The fact that we

achieved a 37% year-on-year increase in ordinary income in real terms in such an environment is due

to the significant contribution to earnings made by the E&P and Petrochemicals businesses. I believe

this is the result of the current management plan focusing on expanding the E&P business and boost-

ing petrochemical production capacity by upgrading our CRI (Chemical Refinery Integration) initiative.

It is also a welcome validation of the plan currently under way.

Such results contrasted with our Refining business, which performed far from adequately. As a

company that operates in an extremely changeable environment, we aim for constant, stable growth

by building a business portfolio that allows other businesses to compensate when a particular business

performs badly. During the year under review, in some ways we can say that this approach was a

success, as we maintained a level of profitability on an overall basis. However, we are by no means

satisfied with this situation. Such low earnings from our core Refining and Marketing businesses, which

are significant elements of the Nippon Oil Group in terms of both assets and sales, is something that

we take very seriously. The extent to which we leverage the benefits and potential of having the top

market share in Japan to improve these businesses will be a major issue in the coming fiscal year. We

are committed to tackling and resolving this issue.

The Refining business faced the challenge of high crude oil prices in the fiscal year under review, and it seems thatsome issues still remain in terms of reducing and passing on costs. What is your outlook for this business?

Higher costs from safety measures implemented ahead of schedule will recedesomewhat. Also, we are seeking our customers’ understanding on price risesfor petroleum products as a result of rising crude oil prices.Major issues during the fiscal year ended March 31, 2007 were continuing problems at refineries and the

costs incurred by them, or by maintenance efforts aimed at preventing such problems in advance. In addition

to these safety measures, we actively brought forward as much other planned spending, including that related

to asbestos countermeasures and soil remediation. This led to an increase in costs. Since the influence of

these factors will disappear from fiscal 2007 onwards, costs will begin to return to normal levels.

Another issue we faced during the year under review was the difficulty in fully reflecting the increased

cost of petroleum products, brought about by the high price of crude oil, in market prices. Everyone

needs petroleum products, as they are essential to modern lifestyles. We thus see the stable provision

of petroleum products as an important mission to society, and one which we have continuously striven

to fulfill. Customers, though, have to play a part by bearing some of the required costs. However, we

acknowledge the idea that increases in the price of crude oil, that is to say an increase in the input cost

to our downstream operations, is something that we should absorb through our own efforts. Already,

during the past eight years we have achieved around ¥210 billion in cost reductions, reflecting a large

portion of this in the prices of our petroleum products. Of course, cost reduction is a constant theme

for any company, and we do not intend to pull back from such activities. Therefore, for our part, we

must obviously continue to robustly pursue cost cutting. However, with the current high crude oil prices,

it will become necessary to ask our customers to bear some of the burden, even though we are able to

absorb some of these costs through our own efforts. Although crude oil prices may remain high mov-

ing forward, we will work to enhance earnings in our downstream operations by reflecting changing

costs in our product prices, with the understanding of our customers.

As you mentioned, demand for petroleum products dropped sharply in Japan during the fiscal year under review.Can you tell us about your predictions for future developments and how you plan to respond?

We expect demand in Japan to continue to decline, but we are already pursu-ing countermeasures.During the fiscal year under review, demand for petroleum products in Japan fell by 5.2% compared to

the previous year. Although most of the decline in demand for heating fuel was attributable to a record

warm winter, the drop in demand for industrial fuels, gasoline, kerosene and similar fuels was due to the

large impact of end-users switching to different fuels. This trend is being driven by social changes, includ-

ing the spread of hybrid cars and other fuel-efficient vehicles, and the shift to all-electric homes. The

Japanese Government is predicting an annual drop in demand of 1.8% over the next five years, and we at

Nippon Oil feel that fuel-use patterns are currently at a turning point. We believe such developments are

inevitable amid diversification of energy sources driven by a variety of considerations including environ-

mental issues. That is not to say, however, that we are simply sitting idly by while demand for our petro-

leum products decreases. In fact, we are already implementing a range of responses.

First is the institution of an integrated energy system structure to provide energy in a range of

forms other than oil, according to the needs of our customers. However, being an integrated energy

company involves more than simply indiscriminately entering a range of non-oil energy businesses.

Rather, it means expanding our presence in fields peripheral to oil, after thoroughly researching the

fields in which we can leverage the expertise, technology and infrastructure developed through the oil

business, as well as our customer base, to establish Nippon Oil in a competitive position. For example,

in the electric and gas power businesses, we are not competing head-on with dedicated utilities com-

panies. Instead, we are pursuing a niche strategy, limiting ourselves to fields where we can put our

strengths to use. In fuel cells, drawing on the technology and distribution network that we developed in

the oil business, we are aiming to use ongoing innovation to create new markets where Nippon Oil can

capture a leading position.

I would like to introduce some of our concrete initiatives in this area. In the natural gas and LNG

business, during fiscal 2006, we began operating two LNG terminals, using idle land at refineries and

Q3

Annual Report 2007 NIPPON OIL CORPORATION 13

disused oil terminal sites. The terminals act as domestic bases for supplying gas companies and ordi-

nary households. In the electric power business, we expect to acquire generating capacity of roughly

1.8 million kW in fiscal 2008. This will be achieved using electric power generation facilities that make

use of residues generated during the refining process, and a natural gas power plant in Kawasaki that

is under construction in a joint project with Tokyo Gas Co., Ltd., which is scheduled to start operating

in 2008. We are also a pioneer in the field of fuel cells, said to be the ultimate energy system, having

developed the world’s first kerosene- and LPG-powered residential-use fuel cell systems. Although the

business is still in its infancy, based on business alliances with Japan Energy Corporation and Cosmo

Oil Co., Ltd., we are promoting future compatibility with devices of both companies as well as cost

reductions, thus promoting the early adoption of fuel cells powered by oil fuel. We are committed to

implementing these initiatives to realize our Group philosophy, “Your Choice of Energy,” as we move

toward becoming an integrated energy company providing the types of energy required by our cus-

tomers, and to become the leader in the Japanese energy industry. (See the Gas, Power and Renewables

section on page 32 for details.)

Also, despite the fact that demand will decline in Japan, oil is still expected to account for 40% of

primary energy demand in 2030, a forecast echoed by the Government’s national energy strategy.

Transport, in particular, is expected to remain heavily reliant on oil for fuels such as gasoline and jet

fuel. We therefore see a continuing need to fulfill our mission of supplying oil in the form of fuel.

Additionally, if Asia as a whole is considered, demand is actually expected to increase. To respond

flexibly to such overseas demand, we have preempted competitors in improving export facilities at

refineries and boosting our export capacity to 200,000 BD. We aim to develop our presence as an oil

company in Asia by realizing internationally competitive refineries through active efforts to reduce costs

and improve efficiency.

It seems that CRI contributed significantly to earnings in the fiscal year under review. Will this continue from fiscal2008 onwards?

I believe that acting earlier than competitors in upgrading our CRIinitiative has been the most successful strategy of the third medium-termmanagement plan.Both petroleum and petrochemical products are produced by refining crude oil. Accordingly, companies

with oil refining facilities have a distinct advantage over dedicated petrochemical product manufacturers

when it comes to manufacturing base petrochemical products. Nippon Oil has the significant added

advantages of existing expertise and high market share. Specifically, our refining capability is unrivaled in

Japan, we have the advanced technologies and facilities to make high-value-added petrochemical prod-

ucts from middle and heavy distillates, and we have a long history of manufacturing and marketing petro-

chemical products. For example, in paraxylene, one of our mainstay products, we are the world’s second

largest supplier, behind only Exxon Mobil. Additionally, we can realize beneficial synergies with our petro-

leum products business by channeling raw materials into petrochemicals production to alleviate the

problem of excess stocks of petroleum products.

We have identified propylene, paraxylene and benzene as strategic products for CRI. This is

because demand conditions for these three base petrochemical products, and their derivatives, are

expected to be tight due to growth and expansion in Asian markets, particularly China. The third

medium-term management plan calls for Nippon Oil to boost its annual production capacity for

propylene and paraxylene to 0.8 million tons and 1.4 million tons, respectively. The Olefin Conver-

sion Technology (OCT) installation at our Kawasaki Operations Center, completed last year, and the

paraxylene manufacturing alliance with Mitsubishi Gas Chemical Company have brought this capac-

ity in range. From fiscal 2007, these various initiatives will make contributions throughout the full

fiscal year, and we will maximize income by further optimizing the production of petroleum prod-

ucts and petrochemical products. (See the Refining and Petrochemicals section on page 26 for details.)

High crude oil prices are boosting income in the E&P business, but production volumes are not increasing. How doyou see things developing?

We do not intend to recklessly pursue production volume to the extent that weoverlook profitability.In the fiscal year under review, ordinary income in the E&P business exceeded ¥100 billion for the first

time, reaching ¥113.8 billion. This performance was helped by crude oil prices reaching record highs

during the period. Since commencing overseas upstream operations in 1968, we have built up technolo-

gies and expertise centered on the four core regions of Southeast Asia, Oceania, the U.K. North Sea and

the U.S. Gulf of Mexico. Believing that this business is the key to the Company’s growth, we have devel-

oped it from a long-term perspective, investing both funds and human resources. These efforts have

borne fruit, and production volumes have grown steadily over the last few years, reaching 153,000 BD in

2006 compared to 66,000 BD in 2003.

One of the pressing issues we face is boosting production and replenishing and expanding reserves.

Looking at the fundamentals, achieving the initial targets of the third medium-term consolidated manage-

ment plan seems challenging. Specifically, our decision to focus on profitability amid an environment of

rising asset valuations caused by high crude oil prices and fierce competition for resources has made it

difficult for us to purchase assets in production. I place greater emphasis on profitability than on simply

increasing production volumes and reserves. We operate our business with funds entrusted to us by

shareholders and this means we cannot neglect profitability for the sake of increasing assets in our upstream

operations. We are interested in long-term expansion of the business rather than achieving short-term

numerical targets. Accordingly, we do not intend to achieve the target by lowering our investment standard.

Rather, we will increase the numbers by taking a long-term view. This will involve concentrating invest-

ment in regions and projects where we can use our expertise, with the aim of minimizing risk and thus

capturing projects with an attractive risk-return ratio. Continuously enhancing our technologies and exper-

tise will also be a factor.

An example of this approach is our May 2007 acquisition of a large-scale oil field already in pro-

duction in the U.S. Gulf of Mexico. We see this oil field as highly economical, as we expect to increase

production through further exploration and development. We have also made the decision to move to

the production stage at the Phuong Dong oil field, located close to the Rang Dong field in Vietnam

where we are currently in production. Since the production, storage and shipping facilities of the Rang

Dong field can be used, this is an economical project with low investment requirements.

Q5

Annual Report 2007 NIPPON OIL CORPORATION 15

Moving forward, our basic approach for this business will be to expand over the long-term by

balancing risk and growth through a combination of asset acquisition, a low-risk activity, and relatively

higher risk exploration activities. To achieve this balance, we will take into account risks and the prices of

production assets at the relevant time. However with the prices of production assets expected to remain

at high levels, we are considering a slight shift in favor of exploration in the fourth medium-term consoli-

dated management plan. We plan to move forward to create an exploration investment portfolio with a

balanced risk profile. This will be achieved by balancing low-risk projects with high upside potential of

peripheral areas of our oil fields in production, mainly in the four core regions where we have extensive

expertise, with high-risk, high-return projects such as deep-water exploration, which offers the possibility

of yielding large-scale reserves. (See the Exploration & Production section on page 24 for details.)

In addition to your alliance with Japan Energy Corporation designed to augment refining competitiveness in theAsia region, you have formed a tie-up with SK Corporation of Korea and concluded a memorandum of understand-ing on long-term cooperation with China National Petroleum Company (CNPC). How do these alliances fit in withyour strategy to expand the business globally?

We consider the oversupply problems in Japan and our Asia strategy as one.Our alliance with Japan Energy is wide-ranging, but the most promising element of it is the integrated

operation of our adjacent refineries in the Mizushima complex. The aim is to combine the respective

strengths of the two refineries: the comprehensive petrochemical production facilities and export-focused

shipping facilities of the Nippon Oil Group, and the extensive heavy oil cracking facilities of Japan

Energy. In this way, we are aiming to develop a refinery that is competitive on an international scale to

a level that would be impossible by either company acting alone.

The tie-up with SK Corporation and long-term cooperation with CNPC are aimed at creating a

strategy for the Asia market as a whole in conjunction with the top oil companies in their respective

countries. Currently, various teams are carrying out studies, but we are confident that these alliances

will produce real results. (See the Strategy in Asia section on page 18 for details.)

As I have already mentioned, demand for petroleum products in Japan is declining. Failure to

respond to this will result in oversupply, and this is recognized as a problem throughout the industry.

At Nippon Oil, we are examining strategies to help us prevail in such an environment based on every

possible scenario.

Fiscal 2007 marks the final year of the third medium-term consolidated management plan. Can you tell us aboutthe progress made so far and your forecast for achieving your targets?

Target for ordinary incomeOrdinary income for fiscal 2008 is expected to exceed the ¥190 billion target, excluding inventory valu-

ation factors. We are also making efforts to achieve the 10% target for ROE.

Cutting costs and improving efficiencyWe are aiming to capture ¥17 billion from cost reductions and improved efficiency. In the last two

years, costs have increased by ¥6.9 billion. However this was partly attributable to changes in the operating

environment including the high price of crude oil and equipment and materials. Another cause was

costs associated with improving safety measures at refineries and environmental activities. In fiscal

2007, we are projecting a reverse of these costs and coupled with a range of rationalization and effi-

ciency improvement measures, including enhanced distribution efficiency, we expect to meet our tar-

get for cost reductions and improvements in efficiency.

Capital expendituresThe medium-term management plan initially called for capital expenditures of ¥500 billion over the term

of the plan, focused on growth areas. This reflected the need to earmark the majority of cash flows as a

foundation for realizing our growth strategy. However, we now expect capital expenditures over the term

to amount to ¥686 billion, due to factors including a need to build up investment aimed at strengthening

our growth strategies, such as the E&P business and petrochemical business. Specifically, we plan to use the

increase for a higher number of investment opportunities on which we expect a return than was envisaged

in the original plan. These potential investment targets have been selected based on stringent assessments.

Interest-bearing debtIt will be difficult to reduce the level of interest-bearing debt below the plan’s initial target of ¥900 billion

by March 31, 2008. This is mainly because of the impact of increased working capital caused by high

crude oil prices. However, we expect to slightly exceed the initial target of 70% for the ratio of interest-

bearing debt to equity.

As the President, how do you balance the needs of shareholders and employees, both two important stakeholder groups?We strive to meet the expectations of shareholders while also taking goodcare of our employees.Since we operate our business using funds entrusted to us by shareholders, we have a responsi-

bility to use this investment to boost income and provide returns. To achieve increased income, it

is of course essential to respect employees, business partners and customers, and comply with

laws and regulations. It is, however, also essential to conduct business activities in a fair and

honest manner and diligently fulfill our corporate social responsibility (CSR) through environ-

mental and safety initiatives.

Nippon Oil has taken the initiative in responding to the changing environment by pursuing growth.

The attitude of our employees is the driving force behind this. This attitude, which allows employees to

cope with change, stems from the corporate culture created following the 1999 merger of Nippon Oil

and Mitsubishi Oil, which combined the best aspects of our respective corporate cultures. The Com-

pany was ranked in the top 20 in the Best Companies to Work For survey conducted by the Great Place

to Work® Institute Japan in 2006. Also, a survey of the level of awareness of CSR and corporate ethics

among our corporate officers and employees found that trust in the Company, employee motivation,

and sense of involvement in CSR were all at high levels. This kind of ethical attitude and motivation is

something we must maintain and enhance by continuing to nurture our employees. However, this is

not any indication of the relative priority given to employees, nor does it mean that all our efforts are

for the benefit of employees alone.

Moving forward, in an operating environment characterized by dramatic change and intensify-

ing competition, continued growth of the Company will only be possible if we win the trust of cus-

tomers by helping to enrich their lifestyles through the ethical attitudes and high levels of CSR

awareness of our employees. It is this growth that will enhance corporate value, and ultimately re-

turn profits to our shareholders.

Finally, what do you consider the key points for the next medium-term consolidated management plan?Our operating environment has changed significantly since we formulated the last medium-term man-

agement plan. However, the changes that we face going forward will be even more dramatic, with

decreasing demand for oil in Japan, rising demand for oil and petrochemicals in Asia, higher crude oil

prices, fierce competition for natural resources, and ever more severe environmental problems.

Our fourth medium-term consolidated management plan will start in fiscal 2008. It will focus on

successfully responding to the changes in our operating environment. Nippon Oil is currently faced

with significant risks, but also significant opportunities. The main challenge of the next medium-term

management plan will be the extent to which these risks can be properly managed and the degree to

which we can tap into business opportunities through shrewd use of our resources, all with an eye on

the changing operating environment. In preparation for this, we are currently focusing our expertise on

business strategy, investment strategy, shareholder returns and other aspects of capital strategy, and

our internal systems.

Despite the significant changes in operating environment, our basic strategy of becoming an inte-

grated energy company will still form the basis of the fourth medium-term plan. With the decline in

demand for petroleum products in Japan, I believe that steadily working on this basic strategy will be

more important than ever in growing the Company and increasing corporate value. The application of

initiatives based on this basic strategy throughout the period of the first three medium-term consoli-

dated management plans has created a foundation for our future. Moving forward, we will continue to

bolster this base while reaping the benefits of business and improvement initiatives we have imple-

mented to date.

The Nippon Oil Group’s E&P businesses in Southeast Asia comprise crude oil and natural gas

production in Vietnam, Malaysia and Myanmar. We are also involved in work to develop gas

fields and construct an LNG plant as part of the Tangguh project in Indonesia in preparation

for the 2008 launch of our new LNG business, encompassing the production of gas and

production and marketing of LNG.

VietnamThis is one of the Company’s main projects, and since the 1992 acquisition of interests in this

project, we have moved into exploration, development and production as an operator.

Cumulative production volume in the Rang Dong oil field exceeded 135 million barrels. The

oil field itself is unique in that it consists of a reservoir in a fracture within the granite bed-

rock. The Nippon Oil Group’s fracture analysis technology is highly regarded worldwide. Other

features of our operations at this oil field include the use of solar and wind power to provide

some of the power used at our offshore production facilities. Also, a project whereby associ-

ated gas generated during production is effectively used by piping it to power plants in Viet-

nam was recognized as a Clean Development Mechanism (CDM) Project under the Kyoto

protocol in February 2006. This has reduced annual emissions of greenhouse gases by annual

average 680,000 tons and demonstrates the environmentally friendly aspect of this project.

In addition to the analysis and environmental technologies introduced above, the Group

aims to use its horizontal drilling and other technologies to further increase production volumes

and enable stable operations.

MalaysiaOur Malaysian project comprises an LNG business featuring an integrated operating system cover-

ing upstream through to downstream operations. Since acquiring an interest in the SK-10 block in

1987 we have moved into exploration, development and production as an operator. In 1989, we

also acquired an interest in the SK-8 block. The natural gas produced from these blocks, located

offshore Sarawak, Malaysia, is sent via pipeline to the liquefaction plant of Malaysia LNG Tiga Sdn

Bhd, in which Nippon Oil has a 10% interest, to be processed into LNG and sold. The plant pro-

duced 6.9 million tons of LNG in fiscal 2006. The condensate produced in association with natural

gas is also sold.

MyanmarProduction of natural gas began in May 2000 in gas fields discovered in December 1992. The gas

is sold via pipeline to PTT, Thailand’s state oil company. The condensate associated with natural gas

production is also sold, as with the project in Malaysia.

IndonesiaThe Nippon Oil Group became involved in the Tangguh project at the exploration stage, earlier than

most of its partners. This is our second LNG project after the Tiga project in Malaysia, and we are

developing gas fields and constructing an LNG plant with a capacity of approximately 7.6 million

tons per year in preparation to begin LNG production at the end of 2008.

Refining

Expanding Business Opportunities in AsiaIn contrast to the expected decline in demand for petroleum products in Japan, demand in

China and other Asian countries is projected to increase. In particular, a certain level of growth

in Asia is expected for heavy fuel oil, while demand is anticipated to drop significantly in Japan.

In such circumstances, we have increased loading capacity at refineries for export prod-

ucts to 200,000 BD, and plan to increase this further to 230,000 BD during fiscal 2007.

We have also agreed to increase the volume of commissioned refining for China National

United Oil Corporation (China Oil) to 50,000 BD from April 2007. This project utilizes our

refining capacity, which is the largest in Japan, and offers the same benefits as secure ongo-

ing exports. Accordingly, the project is mutually beneficial to both companies.

Alliances to Enhance Our International CompetitivenessWe are increasing exports of petroleum products, but competition in the international market remains

fierce. Enhancing the competitiveness of our refineries is therefore a key issue. The Nippon Oil Group

has a track record of making use of outside consultants to perform comparative evaluations of refinery

competitiveness and devising strategies aimed at creating a highly competitive refining group in the

Asia region.

In June 2006, we concluded a comprehensive business alliance with Japan Energy Corporation.

The agreement aims to enhance the competitiveness of a full range of areas, including upstream

operations, refining, distribution and fuel cells, but the main focus is on integrating operations at

both companies’ Mizushima refineries. The ultimate aim is to develop refineries which are highly

competitive internationally.

Nippon Oil has also agreed to enter into a strategic business and capital alliance with SK

Corporation of Korea. Working in tandem, the companies will pursue growth strategies includ-

ing enhancing the competitiveness of our refining and petrochemicals operations in Asia, and

expanding overseas business.

In April 2007, we also concluded a memorandum of understanding regarding long-term

collaboration with China National Petroleum Corporation (CNPC), the parent company of

China Oil with which we have maintained a good relationship through commissioned refin-

ing operations. Under this agreement, the companies aim to further enhance their current

positive relationship through joint activities and cooperation in a wide range of fields cover-

ing upstream and downstream operations, and including new energy and energy-saving activi-

ties. Moving forward, the companies will grow together leveraging their respective competitive

advantages.

CRI StrategyOur Chemical Refinery Integration (CRI) strategy aims to bolster the Company’s propylene and

paraxylene operations for the rapidly growing Asian market by leveraging our strengths in refining

operations. For propylene, we constructed an Olefin Conversion Technology (OCT) installation

focused on exports at our Kawasaki Operations Center. This facility, which includes a refrigeration

tank and loading facilities for large vessels, commenced full-scale operation in September 2006.

We will also respond to future growth in paraxylene demand from Asia by working to raise

paraxylene production capacity to 1.4 million tons through the CCR-PLAT reformer installation at

the Sendai refinery and a business alliance with Mitsubishi Gas Chemical.

Lubricants

Two-base Lubricant Manufacturing Network Serving Northern andSouthern ChinaIn September 2006, Nippon Oil commenced full-scale operation of a lubricant plant in

Guangzhou, China, with an annual capacity of 27,000kl. There is a growing number of

automakers and other companies expanding their manufacturing activities in Guangzhou and

the surrounding south China region, leading to soaring demand for lubricants.

Nippon Oil is putting its proprietary technologies to work at this new lubricant production

plant in the region, manufacturing and marketing products including auto engine oil that

supports high levels of fuel efficiency, and environmentally friendly lubricating oil for indus-

trial users. The plant also manufactures and markets lubricating oil for ships, taking advan-

tage of its prime location in the Pearl River delta, which is ideally located for sea transport.

This new plant joins the Tianjin Nisseki Lubricants & Grease Co., Ltd. plant, at which pro-

duction capacity was increased in May 2006. As a result, we now have a two-base manufac-

turing network serving the northern and southern regions of China, and the Nippon Oil Group

has boosted its annual production capacity for lubricants in China to 82,000kl.

We also market refrigeration oil for household appliances based on an exclusive manu-

facturing and marketing agreement with the CNPC Group. Refrigeration oil is used in com-

pressor units that drive air conditioners, refrigerators and other cooling devices, and as such,

requires high technical specifications and strict quality management. The CNPC Group has

made use of our advanced base-oil manufacturing and commercialization technologies to

produce refrigeration oil at its local refineries. We anticipate strong sales growth amid surg-

ing demand for refrigerators and air conditioners in the domestic Chinese market.

We are also rolling out our ENEOS-brand high-performance automotive oil in China. This

oil is sold at our service stations in Japan and is well supported by consumers. Going for-

ward, we will substantially strengthen our lubricants business in China as well as expanding

the marketing of ENOS-brand oil.

Positioning of Upstream Operations in the Nippon Oil Group

Oil and gas exploration and production (E&P) activities are an increasingly important part of

the Nippon Oil Group’s growth strategy. In its third management plan (2005–2007) the Group

has the goal of boosting its production to 180,000 BOED in 2007 on an equity basis according

to our investment in the project companies. However, achieving this within the planned time

frame now looks challenging because of difficulties in making effective asset purchases and

investment in exploration blocks. These difficulties are due to changes in the business environ-

ment since the plan was formulated, specifically, fierce competition for resources and rises in

the cost of procured equipment and materials. Despite this, the Nippon Oil Group will empha-

size profitability, as it implements strategies geared toward expanding its business while con-

stantly monitoring changes in the market.

The Nippon Oil Group focuses its management resources on its four core areas of South-

east Asia, the U.K. North Sea region, the U.S. Gulf of Mexico region, and Oceania. Additionally,

the Group is enhancing its exploration activities to further replenish reserves which are essen-

tial for E&P business continuation. We plan to move forward to create an exploration invest-

ment portfolio with a balanced risk profile. This will be achieved by combining asset acquisition

in peripheral areas of our oil fields in production, where we have extensive expertise and new

exploration activities in North Africa and the Middle East and in deep with high potential.

Also, the Nippon Oil Group is actively expanding its operations of natural gas and LNG-

related business (See page 32). We are participating in the Malaysia LNG Tiga Project and Indonesia

Tangguh LNG project, both of which are covering processes from exploration and development

to liquefaction and marketing.

Activities During Fiscal 2006 and in the Near Future

In the E&P Business, in October 2006, we began construction work to expand facilities at the Rang

Dong oil field in Vietnam, with the aim of increasing crude oil production. We are also preparing

to start production in the Blane oil field in the North Sea during 2007. Meanwhile, work to develop

gas fields and build an LNG plant are proceeding smoothly at the Tangguh LNG project in Indo-

nesia, with supplies of LNG scheduled to start at the end of 2008. Looking at the oil sand busi-

ness in Canada, completion of the Syncrude 21 Stage 3 expansion project boosted capacity to

350,000 BD, of which the Nippon Oil Group is entitled to 17,500 BD.

In Vietnam, we made the decision to move to the development stage at the Phuong Dong

oil field, located close to the Rang Dong oil field where we are engaged in production. This

enables low-cost production at the Phuong Dong field by making use of the production, stor-

age and loading facilities of the Rang Dong field. Production at the Phung Dong field is slated

to commence at the end of September 2008. Initial production volume is expected to be 23,000

BD. We have also decided to move to the development stage at the Saderi gas field in Malaysia.

In addition, the Group was awarded interests in six new exploration blocks in the U.K.

North Sea in a licensing round held by the U.K. government in 2006. The Group is operator in

four of the licenses.

Average production volumes for Group companies during the fiscal year under review

were slightly down year on year at 152,000 BD. This reflected delays to make facilities opera-

tional again in the U.S. Gulf of Mexico region, which suffered hurricane damage in August

2005, as well as difficulty in making effective investments due to intensified competition for

resources and higher prices of procured equipment and materials.

Furthermore, in May 2007, we made a joint bid with Mitsubishi Corporation to purchase a

23.2% stake in the K2 oil field from Anadarko Petroleum Corporation, a major U.S. indepen-

dent oil company, which held a total 65% stake. Of this, Nippon Oil holds an 11.6% stake in

the field. The K2 field is located in deep waters offshore the state of Louisiana and currently

produces 40,000 BD of crude oil and natural gas. Large oil and gas fields are continuing to be

discovered and developed in the area around the K2 field, and further exploration and devel-

opment is expected to yield increased oil reserves in the future. Network

Response to Declining Demand for Petroleum Products in Japan

In response to a changing operating environment due to declining demand for petroleum

products in Japan, the Nippon Oil Group is working to thoroughly reduce costs and improve

efficiency while also preempting competitors in engaging in a range of response initiatives.

Growing Commissioned Refining Operations and Exports

In 2006, demand for petroleum products in Japan fell 5.2% year on year. In particular, demand

for gasoline fell by 1.5% and demand for heavy fuel oil A and heavy fuel oil C fell significantly as

the shift to gas and coal progressed. Looking forward, no great change is expected in this trend.

In contrast, we expect demand for petroleum and petrochemical products in the Asian

region, particularly in China and India, to grow along with the region’s economic develop-

ment. Moreover, the progressive implementation of environmental regulations is boosting

demand for low-sulfur (10 to 50ppm) diesel fuel.

In response to these contrasting domestic and overseas situations, the Nippon Oil Group

intends to proactively expand its exports of jet fuel, low-sulfur diesel fuel, heavy fuel oil C, and

other petroleum products in addition to efforts to grow commissioned refining operations.

Accordingly, the Group plans to strengthen its export capacity of each of its refineries. In the

first stage of this project, we invested a total of ¥1.1 billion in fiscal 2006 to increase capacity of

the export facility to 200,000 BD. We plan to increase this further to 230,000 BD during fiscal

2007. These efforts will enable us to respond flexibly to both demand in Japan and exports

based on trends in overseas petroleum product markets.

Annual Report 2007 NIPPON OIL CORPORATION 27

Furthermore, the Group increased the volume of commissioned crude oil refining opera-

tions on behalf of China National United Oil Corporation (China Oil). Increasing demand for

petroleum products in China has steadily boosted this volume each year since we undertook the

commissioned refining of 20,000 BD in July 2004, increasing to 50,000 BD from April 2007. This

deal is one example of how we export petroleum products. It also benefits both parties by utiliz-

ing Japan’s largest refining capacity to allow both Nippon Oil and China Oil to secure ongoing

supplies of the products they require. We also concluded a memorandum of understanding with

CNPC, China Oil’s parent company, indicating the two companies’ intention to grow together by

fully leveraging their cooperative relationship and respective competitive advantages. (See the

Strategy in Asia section on page 18 for more information.)

Advancing Our CRI Strategy

Nippon Oil is implementing a strategy to use its refinery capacity in fields other than petro-

leum production. Central to these efforts is the Chemical Refinery Integration (CRI) project.

This project leverages the Company’s strength in creating petrochemical products from crude

oil using its refinery facilities. The objective is to operate an optimally efficient production sys-

tem that enables us to respond quickly and flexibly to trends in demand for petroleum and

petrochemical products. The project places particular emphasis on increasing production capacity

for paraxylene and propylene, for which rising sales volume is expected in China and other

Asian countries. During the period of the third management plan, Nippon Oil plans to increase

its annual production capacity for propylene and paraxylene to 0.8 million and 1.4 million

tons, respectively. As part of the CRI strategy, we constructed facilities for propylene produc-

tion using Olefin Conversion Technology (OCT) at the Group’s Kawasaki Operations Center,

with full-scale operation commencing in September 2006. At the Sendai refinery, we are

increasing production of xylene (a base material for paraxylene) and propylene, while also

carrying out construction of a Continuous Catalyst Regenerator (CCR) platformer and propy-

lene splitter, scheduled for completion in August 2007.

Expanding Electric Power Operations

Recently, the balance of demand for petroleum products is shifting, with declining demand for

heavy oil fractions and a greater proportion of demand for light oil fractions such as gasoline and

kerosene. As a result, making effective use of surplus heavy oil fractions is an issue in the industry.

In response to this, Nippon Oil decided to enter the IPP (independent power producer)

field. The Company has a huge refining infrastructure as well as considerable know-how re-

garding the operation of electric power plants.

Negishi refinery

As this initiative entails electric power generation using heavy oil, which is projected to be

produced in quantities that exceed demand, it has the twin effects of rebalancing demand for

heavy oil and stably providing competitive electric power.

Nippon Oil initiated wholesale independent power producer (IPP) operations in 1998 at

the Osaka refinery. Now, we are operating IPP facilities at five refineries (Osaka, Yokohama,

Negishi, Marifu, and Muroran). These facilities have a total power supply capability of 700,000kW,

making Nippon Oil the third-largest IPP company in Japan.

Full-conversion Strategy

As another strategy to deal with surplus heavy residues, Nippon Oil is implementing utility

integration with petrochemical companies operating in the Mizushima complex. This plan is

slated for completion in the spring of 2009 and involves the construction of a solvent

deasphalting unit. This will allow the processing of heavier grades of crude oil, boost produc-

tion of middle distillates and reduce production of heavy fuel oil C. Additionally, it is planned

to provide the residue extracted from the unit as fuel to the neighboring petrochemical

companies. This plan is aimed at achieving yet higher levels of value-add at the Mizushima

refinery while also contributing to energy-saving efforts and enhanced competitiveness in the

Mizushima complex as a whole.

Global Niche Strategy for High-performance Chemical Products

Another principal element of Nippon Oil’s petrochemical operations besides the CRI operations

described previously is the Company’s business manufacturing and marketing high-performance

petrochemical products used in diverse applications. For example, the Company has earned the

top share of the global market for ethylidene norbornene (ENB), a crosslinking agent in synthetic

rubber used to increase the resistance to heat and light (See the Overseas Operations section on

page 36 for more information). The Company also markets such products as high-boiling-point

Super Aromatic Solvent (SAS), applied to a pressure-sensitive paper solvent and synthetic insula-

tion oil, and Xydar, a liquid crystal polymer, which is marketed as a high-performance super

engineering plastic. Created by leveraging the Company’s special technologies and other capa-

bilities, these high-performance functional petrochemicals are generally characterized by high

profit margins and high global market shares, and Nippon Oil targets further expanding the scale

and profitability of functional petrochemicals business in the future as its global niche strategy.

Thoroughly Shifting Emphasis to Efficiency, Productivity and High Added Value

The 1996 relaxation of petroleum product import restrictions halted the trend of growth in the

number of service stations in Japan. Subsequently, intensifying competition began reducing the

number, and the unprofitable facilities were progressively winnowed out by the legalization of

self-service service stations in 1998. Since then, the number has continued decreasing steadily.

Japan currently has approximately 46,000 service stations, of which the Nippon Oil Group oper-

ates about 10,400—the country’s largest service station network. As price-oriented competition

among service stations intensifies, Nippon Oil recognizes that it cannot simply take pride in the

large scale of its marketing network but must implement the following strategies for shifting its

marketing emphasis from quantity to efficiency, productivity and high added value.

The first strategy is to supply highly competitive products. One example is the Group's

environmentally friendly premium gasoline called ENEOS NEW VIGO, which reduces friction

inside engines to enhance both fuel economy and acceleration. Its improved engine-cleaning

capabilities remove grime from air valves and injectors to prevent deterioration in engine per-

formance. In addition, these capabilities generally clean up engine interiors in ways that reduce

the amount of carbon monoxide, hydrocarbons, and NOx in exhaust gases. Nippon Oil has

been a leader in marketing essentially sulfur-free (10ppm or less) gasoline products, which

lower the levels of harmful substances in exhaust emissions. As awareness of environmental

protection issues among consumers increases, products with these kinds of superior environ-

mentally friendly features are steadily growing in popularity to become more competitive in

the marketplace.

Marketing

Annual Report 2007 NIPPON OIL CORPORATION 31

ENEOS Service Station

The second strategy is to build a high value-added service station network. Most Japanese

car owners are meticulous about automobile maintenance. Noting this, the Nippon Oil Group

is seeking to increase the competitiveness of its service station network by emphasizing the

creation of high value-added Dr. Drive service stations. Dr. Drive facilities provide ordinary

vehicle-care services—including lubricant oil checks and changes, car washing and waxing, and

tire sales and changing—as well as statutory vehicle inspections (required three years after new

vehicles are purchased and every two years thereafter), car washing by hand and daily vehicle

checkup inspections, and a range of other high quality vehicle-related goods and services.

Aiming to be the starting place for safe and comfortable driving by offering services just as

dependable as those of trusted family doctors, Dr. Drive facilities always feature nationally

qualified mechanics. This allows all drivers, even those not familiar with vehicular mechanics,

to discuss their issues in comfort. Because these characteristics make Dr. Drive facilities con-

siderably more competitive than ordinary service stations, during the first year after ordinary

service stations are converted into Dr. Drive facilities, their average monthly gross profit grows

by approximately ¥200,000. The number of Dr. Drive facilities has risen rapidly since Nippon

Oil began their full-scale creation in fiscal 2000. As of March 31, 2007, the Group had a net-

work of 2,403 Dr. Drive facilities, equivalent to roughly one quarter of the overall service station

network. In January 2007, Nippon Oil used a range of media and its service stations to adver-

tise the benefits of Dr. Drive facilities as the starting place for safe and comfortable driving. We

will continue to improve quality to respond to our customers’ expectations.

The third strategy is to restructure the network of affiliated service station operators that

manage all Nippon Oil service stations. In addition to the strategies described above, Nippon

Oil is seeking to enhance the competitiveness of its service stations by providing those opera-

tors with advice and assistance related to low-cost management. Further, we consider that

some restructuring is necessary based on the business judgment of affiliated service stations,

with the aims of strengthening the management base, improving management and maintain-

ing and strengthening sales channels. We will continue to consider such steps as necessary in

the future.

Natural Gas and LNG

Nippon Oil is actively expanding its business with an integrated operating system covering the

whole of the natural gas business from exploration to marketing. Also, in downstream opera-

tions in Japan, the Group is proceeding with strategic infrastructure projects focused on spe-

cific regions and business partners. Those projects include constructing LNG terminals as starting

points for natural gas supply, and constructing power plants to create new demand. One example

is the use of existing infrastructure to construct a new LNG importing terminal (160,000kl

capacity) on idle land within the Mizushima refinery, which has been supplying gas to nearby

gas companies and industrial users since May 2006. Nippon Oil has also decided to construct

a new 160,000kl tank to cope with expected future increase in demand for LNG. We plan to

commence operation in fiscal 2011. In March 2007, Nippon Oil also completed construction

of a satellite LNG terminal of 4,500kl capacity for domestic marine shipments on a former

transshipment depot site in Hachinohe, Aomori Prefecture. This terminal provides local city

gas companies and industrial users with natural gas and LNG. Furthermore, we have been

supplying natural gas to JR East’s Kawasaki power plant since June 2006.

Electric Power

Deregulation of the Japanese electric power industry has encouraged a growing number of

companies to enter the electric power business from diverse industries. Wholesale power sup-

ply by independent power producers (IPPs) has been allowed since 1995, and the permitted

scope for the retail electric power supply business of power producers and suppliers (PPSs) has

been gradually broadened since 2000. The Company is well positioned to maintain strong

competitiveness in electric power operations by making good use of its huge refining infrastruc-

ture and by utilizing residue from its refining operations, which is projected to be in surplus, as

fuel for its power generation plants. We plan to earn a stable profit by expanding our electric

power operations to an extent that permits us to make the most of our competitive advantages.

Nippon Oil already has IPP plants at five Group refineries that have a total supply capacity

of 700,000kW, making the Company the third-largest IPP in Japan. In addition to wholesale

IPP operations, the Company has proactively developed its power producer and supplier (PPS)

retail electric power supply business under its third medium-term management plan. Besides

providing power to customers by using the surplus internal generating capacity of the Negishi

refinery and other facilities, since July 2005, the Company has procured power for PPS retail

marketing operations from Frontier Energy Niigata Co., Ltd.—a joint venture created in coop-

eration with Nippon Steel Corp. and Mitsubishi Corp. Furthermore, a joint venture between

Nippon Oil and Tokyo Gas Co., Ltd.—Kawasaki Natural Gas Generation Co., Ltd. has been con-

structing an 800,000kW natural gas-fueled power generation plant that is scheduled to begin

operations in fiscal 2008. A high-efficiency power generation plant fueled with associated gas

is under construction at the Sendai refinery, and the Company is planning retail marketing of

power from that plant from the second half of fiscal 2007. The PPS business in Japan is losing

competitiveness due to the high price of crude oil, leading some companies to withdraw from

the industry. However, the diverse portfolio of fuels used in Nippon Oil’s electric power busi-

ness, comprising natural gas, petroleum coke, associated gas from refineries and residue, enables

us to mitigate the effects of crude oil price rises. Under its policy of environmental protection,

Nippon Oil is also engaged in the wind-power generation business. The Company is operating

a 1,500kW wind turbine at its Akita Oil Depot and plans to increase its wind-power business

in scale.

Total Energy Systems (TES)

Nippon Oil has contributed to increased energy efficiency and reduced energy-related envi-

ronmental impact by developing and marketing petroleum fuel-based cogeneration systems

or supplying electric power from these systems. Making good use of the technologies accu-

mulated in the TES business with a total generating capacity of approximately 350,000kW,

Nippon Oil began providing energy service company (ESCO*1) services for the prefectural

government buildings and the police headquarters in Aomori Prefecture from March 2006

using a highly efficient cogeneration system and comprehensive methods for reducing build-

ings’ energy consumption.

In addition, Nippon Oil was commissioned to provide energy (totaling 55,000 kW) for

three manufacturing facilities operated by Fujifilm Co., Ltd., which has been shifting its fuel to

approximately 1,000,000kW as of March 31, 2008. Also the Company will boost this capacity to

approximately 1,800,000kW, comprised of 700,000kW in IPP operations, 960,000kW in PPS

operations, and 165,000kW in TES operations by March 2009. This will be achieved through

such steps as the procurement of power for PPS business from the Sendai refinery and the

Kawasaki-based joint venture with Tokyo Gas.

Fuel Cells

Since 1986, the Nippon Oil Group has undertaken fuel cell R&D programs that leverage its

advanced hydrogen refining and catalyst technologies. As fuel cells are environmentally friendly,

next-generation energy systems with great potential, the Nippon Oil Group is focusing on fuel

cells as a future key business area. In March 2005, we launched the ENEOS ECO LP-1, the

world’s first residential-use fuel cell system that uses liquefied petroleum gas (LPG) as fuel,

and we had installed a total of 369 units as of March 2007. The Group plans to actively install

this efficient, environmentally friendly product with low CO2 emissions and plans to install

over 250 units during fiscal 2007.

In addition, in March 2006, Nippon Oil launched ENEOS ECOBOY, the world’s first resi-

dential-use fuel cell system that uses kerosene. This product offers a high total energy effi-

ciency level of 84% (compared with around 40% energy efficiency for conventional power

generation). Moreover, the fuel cell system’s CO2 emissions per energy unit supplied are 30%-

40% lower than those of thermal power plants. Since the ENEOS ECOBOY system is capable

of operating in temperatures as low as -10°C, together with the above ENEOS ECO LP-1 sys-

tem, we are able to provide fuel cell systems that can be used anywhere in Japan. The Com-

pany installed 76 ENEOS ECOBOY systems during fiscal 2006 and plans to install around 150

in fiscal 2007.

The Japanese Government is implementing a large-scale demonstration project to promote

the development of fuel cell technology by installing fuel cell systems and acquiring data from

real-world operation. Participants are oil and gas companies and they installed 1,257 fuel cells

over a two-year period from 2005 to 2006. We proactively took part in this project and installed

a total of 435 ENEOS ECO LP-1 and ENEOS ECOBOY systems, the highest number of any of the

participating companies at 35% of overall installations.

Fuel Cells

The fuel cell business also formed part of the business alliance with Japan Energy Corpo-

ration that we formed in June 2006. Furthermore, we formed a fuel cell business alliance with

Cosmo Oil Co., Ltd. in April 2007. With these alliances, Nippon Oil is aiming to promote early

adoption of petroleum-powered fuel cells through the ability to produce devices compatible

with those of the two alliance partners in the future and achieving a further level of cost reduc-

tions. The strategic business and capital alliance with SK Corporation of Korea also includes

fuel cells as part of its R&D alliance.

The Nippon Oil Group intends to continue its efforts to maintain the leading position in

the fuel cell field.

NIPPON OIL CORPORATION Annual Report 200736

With demand for petroleum products in Japan expected to decline, growing demand in China

and other Asian countries presents opportunities for Nippon Oil in commissioned refining and

exports of petroleum products and petrochemical products. Accordingly, we will adopt a flex-

ible approach to exporting with an eye on supply and demand trends and prices in Japanese

and overseas markets. (See the Strategy in Asia section on page 18 for more information.)

We are also expanding sales of lubricants overseas, in line with the overseas expansion of

Japanese automakers. This is one of the pillars of our overseas strategy.

In 1995, Nippon Oil established Tianjin Nisseki Lubricants & Grease Co., Ltd., a China-based

lubricant manufacturing and marketing company in which we have a 40% shareholding. Opera-

tions have expanded steadily, and annual production capacity was boosted by 40%, from 35,000kl

to 55,000kl in May 2006. The Company has also established a Guangzhou-based lubricant-manu-

facturing subsidiary, Nippon Oil (Guangzhou) Lubricants Corporation, which began full-scale

operation of a production plant with a capacity of 27,000kl per year in September 2006. As a

result, with this new company and Tianjin Nisseki Lubricants & Grease, Nippon Oil has created a

two-base, lubricant manufacturing network with a combined capacity of 82,000kl per year that is

well positioned to supply both the southern and northern regions of China.

Nippon Oil has also set up a lubricant manufacturing subsidiary in the U.S. state of Ala-

bama called Nippon Oil Lubricants (America) LLC. In October 2006, this subsidiary commenced

full-scale operation of a lubricant and grease production plant with a capacity of 39,000kl per

year. This is the Group’s first manufacturing base for lubricants in the U.S., where previously,

Nippon Oil marketed products manufactured on a commissioned basis.

We are also continuing to expand our ENEOS Oil brand overseas. During 2006 we began

sales for the first time in a range of countries and regions including the west coast of North

America, the United Kingdom, Turkey and other countries.

Growth in demand for high-performance lubricants is expected to continue in China and

throughout Asia. Targeting increased demand driven by Japanese automakers expanding into

Europe and the U.S., we plan to increase overseas sales of lubricants by 16% year on year

from 187,000kl in 2006 to 217,000kl in 2007.

In terms of petrochemical products, we also supply ENB (ethylidene norbornene) to the

world market using our annual production capacity of 20,000 tons in both the U.S. and Japan.

This capacity is split evenly in a fifty-fifty joint venture with Sanyo Chemical Industries, Ltd. ENB

is mainly used for automotive rubber products and Nippon Oil has captured over 70% of the

world market due to its unique manufacturing process which allows durable products and a

high level of cost competitiveness. With demand also growing steadily, we commenced com-

mercial operation of a new 20,000 ton per year capacity plant in the U.S. in June 2007. As a

result, the level of the Nippon Oil Group’s total ENB production capacity will rise to 60,000

tons per year, thereby further consolidating the Group’s solid position as the world’s leading

ENB supplier.

The Nippon Oil Group engages in the construction business primarily through NIPPO COR-

PORATION (NIPPO). Construction projects include road-paving as well as building construc-

tion, construction and engineering for oil- and other energy-related facilities, and

environmental protection.

In fiscal 2006, although Japan’s construction sector benefited from a recovery in private-

sector investment, the operating environment remained harsh due to declining public-sector

investment coupled with a continued rise in the cost of raw materials caused by a surge in crude

oil prices. In these conditions, the Nippon Oil Group’s construction units strove to obtain orders

for road-paving, civil engineering, and other construction projects, as well as promote greater

sales of products such as asphalt mixture. As a result of these activities and efforts to improve

profitability through cost-cutting and efficiency-boosting measures, the Group achieved a year-

on-year rise in its operating income in the construction sector. Looking forward, although the

environment in the construction industry remains severe, the Nippon Oil Group will continue to

enhance its competitiveness by working to strengthen its technological capabilities and operating

activities while also steadily proceeding with cost reductions and efficiency improvements.

Research & Development

1. Petroleum Products

(1) Initiatives related to biomass fuel

Biomass fuel is important from the standpoint of securing an alternative source of liquid fuel

to existing oil, and in terms of preventing global warming by reducing CO2. In biomass fuel for

gasoline engines, we aim to acquire the capability to supply approximately 360,000kl of

bioethanol per year (roughly 210,000kl crude oil equivalent) by fiscal 2010, in the form of

ETBE (Ethyl Tertiary Butyl Ether). This will be achieved in collaboration with the other companies

in the Petroleum Association of Japan. Since April 2007, we have been preparing plans to begin

trial sales of biogasoline containing bioETBE to verify issues associated with its full-scale intro-

duction. Currently, agricultural produce such as maize is the main raw material for bioethanol.

There are problems, however, in that supplies are limited and there is a possibility that using

agricultural produce to make fuel could push food prices higher. Accordingly, aiming to secure

large-volume supplies of biofuel while allaying these fears, the Nippon Oil Group is develop-

ing manufacturing technology that uses cellulose biomass resources, for which there is no

competition with food applications. Achieving this goal will mean developing integrated manu-

facturing technologies covering all processes from the cultivation of plants to ethanol produc-

tion itself, so we are actively targeting technologies only available from universities and other

research organizations, including technology related to cultivation of plant resources, cellulose

saccharification, and fermentation.

In biomass fuel for diesel engines, we have teamed up with Toyota Motor Corporation to

develop bio hydrofined diesel (BHD) mainly made from vegetable oil and fat. Compared to

existing FAME (fatty acid methyl ester) biodiesel, which is subject to concerns over oxidative

stability and other quality issues, the BHD under development is expected to be of a quality at

least equivalent to that of ordinary diesel. As part of a joint project to commercialize this fuel

with the Tokyo Metropolitan Government, Toyota and Hino Motors Ltd., we are planning to

conduct test runs using this fuel in Tokyo city buses from fiscal 2007.

(2) Effective use of sulfur

In fiscal 2006, we began sales of a new product called Recosul that uses technology we devel-

oped to effectively utilize the sulfur byproduct of oil refining. Recosul is a material for construc-

tion and civil engineering produced by mixing modified sulfur with industrial byproducts such

as steel slag and coal ash or marine byproducts such as scallop shells. It has superior acid

resistance and strength characteristics and is resistant to salt damage.

(3) Initiatives related to GTL

GTL (gas to liquids) technology synthesizes liquid fuel from natural gas. This process results in

clean fuel and a promising high-performance base oil for lubricants. On October 25, 2006, we

set up the Nippon GTL Technology Research Association together with INPEX CORPORATION,

Japan Petroleum Exploration Co., Ltd., Cosmo Oil Co., Ltd., NIPPON STEEL ENGINEERING Co.,

Ltd., and CHIYODA CORPORATION. The association has launched a GTL technology demon-

stration test project. The groundbreaking technology under research is the first in the world to

use unprocessed natural gas containing CO2 as an input.

2. Petrochemical Products

(1) Effective use of C4 fraction

Aiming to effectively use the C4 and C5 fractions that are a byproduct of oil refining and the

manufacture of petrochemical products, we have perfected technology to dimerize the C4 frac-

tion into isooctane using a catalyst developed in house. Full-scale production using this technol-

ogy began in September 2006. In addition to using the resulting isooctane as an octane booster

for gasoline, we are also considering its application as a highly pure isononanoic acid.

(2) Technology to convert heavy oil fractions into petrochemical products

We are researching technology that converts heavy oil, for which surpluses in the refining

process are forecast, into petrochemical products. We call this “Bottom to Chemical” technol-

ogy. One example of this technology is our own HS-FCC (High Severity Fluid Catalytic Crack-

ing). We are planning the construction and operation of a demonstration facility using this

technology. The ultimate aim is to establish commercial technology to produce high yields of

propylene from heavy oil. We are also engaged in development aimed at commercializing our

unique Z-Forming process, which produces aromatics from light naphtha and LPG.

2. CSR Promotion SystemGuided by its basic CSR policy, Nippon Oil is strengthening its system

for the strategic and Groupwide promotion of CSR management. The

Group defined its six focus areas for CSR, namely “Compliance,” “Human

Rights,” “Information Security,” “Corporate Citizenship,” “Environment

& Safety,” and “Quality Assurance.” This was followed by establishment

of the Nippon Oil Group CSR Meeting, led by the president of Nippon

Oil Corporation and attended by the presidents of the Group’s principal

companies, to comprehensively supervise all CSR activities. Six special-

ized committees were also established below the CSR Meeting, result-

ing in a system for deliberation and decision-making regarding the

direction of Group CSR activities. In fiscal 2006, the Nippon Oil Group

CSR Meeting convened twice to discuss matters related to changes in

the standards of conduct and the CSR monitoring.

3. CSR Activities During Fiscal 2006CSR Monitoring

Summary and Objectives

We conduct surveys to gauge the awareness of CSR and business ethics

among executives and employees of the Nippon Oil Group. We have a

fair and neutral independent research organization collect and analyze

individual survey forms and anonymity is maintained, which allows us

to ascertain the true opinions and feelings of Group members.

The survey covers the extent to which our Group philosophy has per-

meated the organization and the extent to which it is put into practice, as

well as the state of communication at actual workplaces. The results are

analyzed and used to help promote CSR. The survey itself also constitutes

an e-learning training program on CSR and business ethics.

Analyzing the state of awareness by different attributes (affiliation,

position, and years of service) helps in the promotion of discussions at

individual organizations and worksites and in the formulation and

execution of specific improvement measures.

Results of the 2006 CSR Monitoring (Assessment & Issues)

We administered our second CSR Monitoring in November 2006. We

maintained the same high level as last year with regard to trust in the

company, employee motivation, and sense of participation (response

rate of 88%), which are all basic elements of CSR. However, we identi-

fied problems with respect to permeation and practice of our Group

philosophy, awareness of the internal reporting system, and risk identi-

fication at the worksite level.

We have made it possible for each worksite to analyze and respond

to issues by posting the details of the survey on the Group intranet.

Business Ethics Training

Case Method Training

We conduct training on business ethics designed to improve the ethical

decision-making of each and every executive and employee. As of April

2007, some 4,600 executives and employees of the Nippon Oil Group

have gone through the training.

We created an original training program with the help and coopera-

tion of Associate Professor Joji Nakaya of the community service depart-

ment at the Graduate School, Tohoku University of Community Service

and Science. Professor Nakaya is a leading proponent of management

ethics education using the case method.

The program seeks to facilitate ethically proper decisions by having

the people faced with making decisions envision beforehand how indi-

vidual day-to-day actions affect stakeholders.

The program centers on group discussions, so it also provides office

members an opportunity to have frank conversations about these issues.

Training Program Results and Future Initiatives

People that have gone through the program have commented that they

learned the importance of doing one’s job while being aware of stake-

holders and how they keenly realized that forthright discussion in the

workplace is essential to preserving the health of an organization. Oth-

ers indicated that it would be desirable to hold regular ethics training

sessions and conduct training in a cross-division, cross-office format. In

response, we are planning to continue to conduct effective training pro-

grams in this area in fiscal 2007 and beyond.

5. Ensuring SafetyBasic Approach

We strive to ensure safe operations. In every process—from exploration

and development to distribution and sales—we make every effort to pre-

vent accidents and disasters before they occur and respond appropri-

ately if such an event occurs.

Nippon Petroleum Refining Co., Ltd. (NPRC) is working to create a

culture in which workers give ultimate priority to safety. The company

reviewed its overall safety management operations with a goal of elimi-

nating labor accidents and injuries and in January 2006 established teams

dedicated to promoting safety at its head office and refineries. Specifi-

cally, we are working to enhance safety activities and safety training not

only at operations and construction units that manage actual worksites

but also for employees of partner companies.

In April 2006 NPRC established the Refinery Project Office to insti-

tute thorough measures designed to prevent accidents at its facilities.

The office is involved in preventing accidents at refineries.

Disaster Prevention Equipment

At refineries, plants, storage terminals, oil depots and gas terminals, we

are instituting measures to prepare for the event of an accident or disas-

ter. These include setting up various disaster prevention facilities.

Countermeasures Against Oil Spills

Storage tanks are surrounded by multiple walls to prevent oil from flow-

ing outside the site in the event oil leaks from a tank. Offshore, there are

oil fences in place and oil recovery vessels at the ready to respond rap-

idly should an oil spill occur.

Countermeasures Against Fire

In readiness for a major fire, we have in place large trucks equipped

with elevated chemical cannons, foam transport vehicles, and foam can-

nons with exceptional fire fighting performance, as well as an array of

large fire extinguishers and equipment for spraying extinguishing foam

and water. For accidents and disasters that happen offshore, disaster-

response vessels with fire fighting capability are kept at the ready.

Mutual Assistance at Refineries and Other Sites

In readiness for a scenario in which a disaster occurs at a refinery or

other site due to a major earthquake and controlling the situation proves

exceedingly difficult to handle by a single site, we have established a

system related to response operations and emergency measures so that

organized assistance can be provided by other members of the Group.

The system seeks to facilitate rapid response to disasters.

Main Initiatives in Fiscal 2006

Comprehensive Disaster Prevention Drills

To be ready for the event of an accident or disaster, we run comprehen-

sive disaster prevention drills on a regular basis. The drills are led by an

internal body established specifically for disaster prevention and are

conducted to help ensure disaster prevention activities are prompt and

precisely targeted. We also conduct a number of other training exer-

cises, including joint disaster prevention drills with local fire departments

and the disaster prevention units of nearby companies.

Incidence of Labor Accidents

Data on labor accidents at the Group’s refineries are shown in the tables

below. In fiscal 2006, there was an increase in injuries that caused lost

workdays, so frequency*1 and severity*2 both worsened.

Initiatives for the Future

In fiscal 2007, we will strive to entrench a culture that puts ultimate pri-

ority on safety and eliminate labor accidents. Specific initiatives will be

as follows.

1. Enhance safety activities aimed at preventative safety

2. Enhance safety management training

3. Enhance our system for providing safety-related instructions to part-

ner companies

We will establish priorities for each division—refineries and plants,

stockpiling bases, oil depots, gas terminals, and distribution (tanker trucks,

tanker ships, and regular trucks)—and work to faithfully carry them out.

Annual Report 2007 NIPPON OIL CORPORATION 45

Nippon Oil Corporation recognizes that maintaining a consistent record

of ensuring that all its business activities and other corporate activities

are fair, transparent, and accountable is an extremely important means

of maximizing corporate value for the Nippon Oil Group as a whole.

Based on this thinking, the Group is working to further expand and

strengthen its corporate governance systems.

Basic Approach to Corporate GovernanceAmid an increasingly severe competitive environment for energy

companies, the Group has a strong need to upgrade its management

strategy development capabilities and establish a system for “rapid and

dynamic decision-making and operational execution” that is responsive

to changes in the business environment. At the same time, the Group

believes it must further augment its efforts to ensure the “transparency

and soundness of management” to respond to the trust and confidence

of all its stakeholders.

To respond to the changes in its operating environment just

described, Nippon Oil has established corporate governance systems with

the following features.

(1) The term of directors is one year, and directors must be approved

by the regular general meeting of shareholders each year.

(2) The presidents of principal Group companies are made members of

Nippon Oil Corporation’s Board of Directors, and management

strategy is debated and decided on a Groupwide basis.

(3) To effectively monitor and supervise management and ensure that it

is sound and transparent, the Company has selected the Board of

Corporate Auditors system, and the majority of members of that

board are outside auditors with specialized expertise.

(4) Nippon Oil is strengthening its Groupwide CSR promotion systems

centered on the Group CSR Meeting.

In April 2006, Nippon Oil established its Internal Control Project

Office, which is advancing with the rechecking and confirmation of the

appropriateness of financial reporting and the effectiveness of all the

Group’s internal control systems.

1. Operational Execution Systems

In Nippon Oil Corporation, the president is responsible for operational

execution decisions regarding items other than those that are defined

by laws, regulations, Nippon Oil Corporation’s Articles of Incorporation,

and Nippon Oil Corporation’s Board of Directors’ regulations as being

items that are to be determined by the Board of Directors. Before mak-

ing operational execution decisions, the president presents related issues

for consideration and discussion by the Executive Committee, which is

comprised of the president, executive vice presidents, senior vice presi-

dents, and other selected directors, and has the role of assisting the presi-

dent with respect to operational execution decisions. Important

operational execution decisions are reported to the Board of Directors,

while reports on the Executive Committee’s consideration and consulta-

tion processes and results are made to the Board of Corporate Auditors.

2. Directors

When nominating candidates for director, the Group assesses each nomi-

nee from a variety of angles, examining their occupational experience,

personality, insight, and other attributes. A list of those candidates

expected to contribute to Group management, who are deemed capable

of handling the responsibilities of director and able to meet the expecta-

tions of Group shareholders, is submitted to the Board of Directors for

further consideration. The final nominees who emerge are then put forth

as candidates for election at the regular general meeting of shareholders.

Under the leadership of the chairman of the Board, the Board of

Directors debates and decides items that are defined by laws, regula-

tions, Nippon Oil Corporation’s Articles of Incorporation, and Nippon

Oil Corporation’s Board of Directors’ regulations as being items that are

to be determined by the Board of Directors. In addition, the Board of

Directors conducts interviews regarding reporting items and monitors

and supervises the president’s operational execution measures and the

performance of duties by each director. With respect to operational ex-

ecution at Nippon Oil Group companies, the presidents of principal Group

companies are added as members of the Board of Directors with the

goal of strengthening Group management. This arrangement enables

debate and decisions regarding important business plans and other

matters at principal Group companies to be conducted by or directly

reported to the Board of Directors. Similarly, regular meetings attended

by Nippon Oil Corporation representative directors and senior vice presi-

dents, as well as by the presidents of the Group’s principal companies,

are held with the aim of maximizing the Group’s corporate value.

3. Auditors

Nippon Oil has adopted the Board of Corporate Auditors system. The

corporate auditors, including outside auditors, attend Board of Directors’

meetings, and pose questions and offer opinions as necessary to clarify

points related to the deliberation, adoption and reporting of board deci-

sions and the formulation of reports. Corporate auditors are also respon-

sible for auditing the performance of directors to ensure that activities

are not in violation of regulations, laws, or the Articles of Incorporation.

In nominating candidates for corporate auditor, Nippon Oil considers

the nominee’s ability to fulfill the duties expected of auditors, the posses-

sion of specialized expertise, a wealth of experience and an outstanding

performance record. Beyond these basic credentials, however, candidates

must also embody the highest ethical standards and have a reputation for

impartiality, fairness, and honesty. Following consideration by the Board

of Directors and approval of the Board of Corporate Auditors, nominees

who are deemed to exemplify these qualities are put forth as candidates

for election at the regular general meeting of shareholders.

Pursuant to regulations established by the Board of Corporate

Auditors and corporate auditing standards, the corporate auditors and

the Board of Corporate Auditors have systems in place for conducting

comprehensive audits as prescribed by law. In addition to the exami-

nation of records relating to financial accounts and important meet-

ings, the auditors receive reports from directors and employees of the

Company and representative directors and officers of subsidiaries

regarding the performance of their duties. These and similar actions

comprise the audits of directors’ performance conducted by the cor-

porate auditors on an ongoing, day-to-day basis. The progress and

results of audits in the areas for which each corporate auditor is

responsible are reported by the auditors at regular meetings of the

Board of Corporate Auditors, which in principle are held twice monthly.

The sharing of results of overall audit activities also takes place at these

meetings. As needed, corporate auditors also receive reports from

directors, investigate decision-related documents, and examine records

related to financial accounts and important meetings. Furthermore, the

corporate auditors work to increase the effectiveness of audits by

receiving audit reports and other reports from the financial auditor and

the CSR Department, which is an internal audit department.

4. Reason for Selecting the Board of Corporate Auditors’ System

Nippon Oil Corporation’s Board of Directors is comprised of directors

thoroughly familiar with the Group’s operations, and they work to main-

tain and increase the efficiency and responsiveness of management. On

the other hand, Nippon Oil believes that augmenting its systems for the

performance of audits by corporate auditors, which have been given

greater authority by successive revisions of Japan’s Company Law, is a

desirable means of maintaining and strengthening management sound-

ness, and it has therefore established its Board of Corporate Auditors.

5. Outside Auditors

Three of the five members of the Company's Board of Corporate

Auditors, listed below, are full-fledged “outside auditors” unaffiliated

with the Company.

Outside auditors use their wealth of experience and knowledge to

pose questions and express opinions at Board of Directors' meetings

regarding agenda items. In fiscal 2006 these included basic policies for

establishing an internal control system, the acquisition of interests in E&P

projects, and the filing of lawsuits. Outside auditors also work together

with standing corporate auditors to further improve sound management

of the Company. To this end, the outside auditors and standing corpo-

rate auditors regularly exchange views with representative directors on

issues including protective measures against so-called hostile takeovers

and corporate governance.

6. Creation of Specialized Support Staff for Auditors

To augment the auditing capabilities of all the corporate auditors,

including the outside auditors, Nippon Oil has established its Secretariat

of Corporate Auditors, which has a three-person staff that is completely

and clearly independent of the Group’s business execution departments

as well as of the Group’s command systems, including the personnel

evaluation system. The Secretariat also serves in the same support

capacity for the independent financial auditor.

7. Compensation of Directors and Corporate Auditors

The compensation of each director and corporate auditor is determined,

based on consideration of the Company’s performance as well as of the

role and contribution of each director and corporate auditor, within the

scope of the total remuneration figure authorized by the General Meet-

ing of Shareholders, in accordance with internal regulations created by a

vote of the Board of Directors in the case of directors and in accordance

with internal regulations created by a vote of the Board of Corporate

Auditors in the case of auditors.

In accordance with resolutions by the Board of Directors and the

Board of Corporate Auditors in May 2005, Nippon Oil has abolished its

system of retirement allowances for directors and corporate auditors.

This decision was made to link compensation for directors and corpo-

rate auditors more closely to their term of service and to the Company’s

business performance.

Remuneration amountNumber of recipients (¥ million)

Directors 20 851

Corporate auditors 5 104

(Outside auditors) (3) (30)

1. The total remuneration includes total bonuses of ¥202 million paid to directorsand of ¥23 million paid to corporate auditors.

2. Employee salaries and bonuses of ¥54 million paid to five employee-directors areexcluded from the total remuneration.

8. Independent Auditor

Nippon Oil has selected Ernst & Young ShinNihon as the independent

auditor to perform audits of its financial accounts. In fiscal 2007, these

audits were carried out by three certified public accountants (CPAs)

employed by Ernst & Young ShinNihon—Atsuhiro Umezawa, Kazuhiko

Umemura, and Takao Kamitani. These personnel were assisted in their

audits by a 21-member staff that included 12 CPAs and 9 CPA assistants.

Total compensation paid to the independent auditor of the Company

is as follows.

Compensation based on work covered by article 2-1 of the certified

public accountant law ¥59 million

Compensation based on work other than that mentioned above

¥147 million

9. Establishment of Internal Control System

As part of its CSR-oriented management, Nippon Oil is putting in place

a system to assure proper operations, and has implemented an internal

control system. The Company strives to further strengthen the system

through reviews in response to changes in internal and external circum-

stances and the operating environment.

NIPPON OIL CORPORATION Annual Report 200756

PERFORMANCE DURING THE YEARConsolidated Financial ResultsOn a consolidated basis, the net sales of the Nippon Oil Group (“the Group”)

in the fiscal year under review increased 8.3% year on year, to ¥6,624.3 billion.

Cost of sales increased 11.9% to ¥6,176.6 because of higher crude oil prices,

and SG&A expenses were down 1.7% at ¥287.9 billion due to lower person-

nel expense and depreciation and amortization. Operating income decreased

by ¥144.2 billion, to ¥159.7 billion. This was due to a negative impact on

earnings of inventory valuation factors, which contributed to sharply higher

earnings in the previous fiscal year. Inventory valuation factors refer to the

effect on the cost of goods sold from the valuation of inventory using the

gross average method to reflect changes in the price of crude oil.

The total sales volume of petroleum products decreased due to a record-

breaking warm winter and fuel conversion. However, excluding inventory valu-

ation factors, operating income rose by ¥31.4 billion from the previous fiscal

year, to ¥168.9 billion, due to improved profits in the oil and natural gas

exploration and production business segment and to improved margins for

petrochemical products.

The Group also recorded non-operating income of ¥26.9 billion, an

increase of ¥21.7 billion, due principally to higher dividend income.

Consolidated ordinary income was down ¥122.5 billion, to ¥186.6 billion.

Excluding inventory valuation factors, consolidated ordinary income was ¥195.8

billion, an increase of ¥53.1 billion from the previous fiscal year.

Due primarily to losses on disposal and sales of fixed assets, other expenses

of ¥14.4 billion were recorded, ¥3.6 billion more than the previous fiscal year.

As a result of the above factors, the Group generated consolidated net

income of ¥70.2 billion, a year-on-year decline of ¥96.3 billion. Net income per

Management’s Discussion and Analysis of Operations

share was ¥48.12, a decrease of ¥65.96 year on year. ROE was 5.9%, or 6.4%

excluding inventory valuation factors.

Refining and MarketingIn the fiscal year under review, due to the tense political situation in certain

Middle Eastern and African oil producing nations and the surging global

demand for oil, the Dubai crude oil price continued its upward march from

the previous fiscal year, passing US$72 a barrel in July 2006 and setting a new

record. Thereafter, the price dropped temporarily heading into winter, but

generally traded in a high range of US$50 to US$60. The average Dubai crude

oil price throughout the fiscal year was US$60.9 a barrel, up approximately

US$7 dollars a barrel from the previous fiscal year.

Foreign exchange rates were affected by higher interest rates in the United

States and Europe, and the average yen-dollar exchange rate for the fiscal

year was ¥117, representing a depreciation of the yen versus the dollar of

around ¥4.

In terms of demand for petroleum products in Japan in the year under

review, the growing adoption of fuel-efficient vehicles led to a year-on-year

decline in domestic demand for gasoline, while a decline in the number of

diesel vehicles in use led to reduced demand for diesel oil. Moreover, demand

for heating oil declined substantially due to a record-breaking warm winter.

Demand for heavy fuel oil A and heavy fuel oil C fell substantially due to the

ongoing shift to gas and coal. As a result, domestic demand for petroleum

products was down across all types of fuel. On the other hand, demand for

petrochemical products was strong, principally for products bound for Asian

countries that recorded continued economic growth.

Annual Report 2007 NIPPON OIL CORPORATION 57

In this environment, the Group established the management objectives

of bolstering the profitability in its core businesses—petroleum and petro-

chemicals—and developing new energy-type businesses. The Group worked

to implement the strategies outlined below.

First, in response to the decline in domestic demand for petroleum prod-

ucts and the growth in demand for petrochemical products in other Asian

markets, principally China, we continued to focus on integrating oil refining

and petrochemical operations by advancing chemical refinery integration (CRI).

The CRI initiative draws on the Group’s ability to produce base petrochemical

products—such as xylene, paraxylene, and propylene—from crude oil using

the facilities of refineries. The objective is to operate an optimally efficient

production system that enables us to respond quickly and flexibly to trends in

demand for petroleum products and petrochemical products. As one facet of

this initiative, in respect of the manufacturing of paraxylene which is in strong

demand, the Group strove to increase its paraxylene production capacity with

the April 2006 commencement of joint production at Mizushima Paraxylene

Co., Ltd., a joint venture with Mitsubishi Gas Chemical Company, Inc. Regard-

ing propylene, the September 2006 commencement of full-scale operation

of production facilities that use olefin conversion technology (OCT) to pro-

duce propylene from distillate that had previously been used as in-house fuel

at the Kawasaki Operation Center of Nippon Petrochemicals Company, Limited

resulted in higher production volume. With solid demand expected to con-

tinue going forward for these petrochemical products, our strategy will be to

focus on producing and selling these products. By increasing production

capacity at Mizushima Paraxylene Co., Ltd., and enhancing facilities at the

Sendai refinery, ongoing projects which are scheduled for completion in 2007,

we plan to further increase the Group's production capacity for paraxylene

and propylene.

In addition, to meet demand for petroleum products in Asian markets

recording continued growth, we bolstered the export capacity of our oil refin-

eries to 200,000 BD. Since July 2004, we have conducted commissioned

refining operations on behalf of China National United Oil Corporation (China

Oil). In April 2006, we raised the contracted volume to 40,000 BD, and have

agreed to increase it further to 50,000 BD from April 2007. As a result of these

measures, despite declining demand for petroleum products in the domestic

market, the Group will endeavor to maintain and raise the capacity utilization

rate of its refineries as it aims to generate and increase earnings.

In addition, we continue to aggressively expand our overseas operations.

In Guangzhou, China, we completed a lubricant plant and commenced manu-

facturing in September 2006, and in the U.S. state of Alabama, we completed

and started commercial operation of a production plant for lubricants and

grease in October 2006.

We also made progress in gas, power and renewables business. In LNG,

which is the focus of growing attention as a clean energy source, in April 2006

we started commercial operations at the Mizushima LNG base, which was

built in the Mizushima refinery to act as an LNG supply center. In March 2007,

we opened another LNG base that was built at a former transshipment depot

site in the city of Hachinohe, and we began to serve city gas companies as

well as traditional industrial users.

In addition to the above initiatives, to respond to great changes in the

operating environment such as higher crude oil prices, changes in the struc-

ture of domestic energy demand and the rapid expansion of Asian econo-

mies, and to achieve sustained growth, we have expanded strategic alliances

with both domestic and Asian companies. In addition to the existing alliance

with Idemitsu Kosan Co., Ltd. and Cosmo Oil Co., Ltd., we reached a

comprehensive agreement with Japan Energy Corporation in June 2006 for a

business alliance extending to a wide range of fields. Under this agreement,

the two companies will consider and implement integrated operation of their

respective refineries in Mizushima, the provision of each other’s products and

joint efforts to rationalize distribution. Also, in January 2007, we reached an

agreement with SK Corporation, South Korea’s largest oil company, for a

business alliance in such fields as upstream operations, supply, and petro-

chemicals. Through these alliances and cooperative relationships, we are

determined to expand our business in Asia and strengthen our competitive-

ness further.

In the year under review, net sales of the Refining and Marketing busi-

ness segment rose 8.6% from the previous fiscal year to ¥5,954.4 billion.

Operating income was down ¥167.9 billion, to ¥29.3 billion. This was due to

a negative impact of ¥175.6 billion on earnings of inventory valuation factors,

which contributed to sharply higher earnings in the previous fiscal year. In-

ventory valuation factors refer to the effect on the cost of goods sold from the

valuation of inventory using the gross average method to reflect changes in

the price of crude oil. Although the total sales volume of petroleum products

decreased due to a record-breaking warm winter and fuel conversion, exclud-

ing inventory valuation factors, operating income increased ¥7.7 billion, to

¥38.5 billion, due primarily to improved margins for petrochemical products.

Details are shown in the diagram below.

Exploration and Production of Oil and Natural GasDue to the rise in crude oil prices, profitability improved in the E&P business.

Regarding measures taken by the production business in the fiscal year

under review, commercial production began at the onshore SE Mananda field

in Papua New Guinea and at the Merganser gas field in the UK North Sea. In

terms of new developments, we continued to make preparations for the com-

mencement of production in the Blane oil field in the UK North Sea. At the

same time, construction continues on an LNG plant at the Tangguh LNG

Project in Indonesia toward the commencement of supply from the end of

2008. In new exploration projects, we made preparations for trial drilling in

exploration blocks off the coast of Libya for which we acquired interests in the

previous fiscal year.

Regarding the purchase of producing assets, we looked closely at pros-

pects from a technical and an economic perspective. Although we tried to

purchase several assets we viewed as promising, ultimately we were unsuc-

cessful as a result of our uncompromising emphasis on profitability.

As a result of the above initiatives, the Group’s average production vol-

ume of crude oil and natural gas (share of production in each project, oil

equivalent basis) was 152,000 BD, 2.8% less than the previous fiscal year.

Net sales in the E&P business segment increased by 12.8%, to ¥203.5

billion, and operating income rose ¥21.7 billion, to ¥113.8 billion, mainly due

to higher crude oil prices. Details are shown in the diagram on page 59.

construction industries continued to face a challenging demand environment.

In this setting, the Group worked to secure construction orders and to bolster

its competitiveness through cost reductions and enhanced efficiency.

Net sales in the Construction business segment rose 8.9% year on year,

to ¥407.9 billion. The segment recorded operating income of ¥10.1 billion, up

¥2.9 billion, year on year due to cost reductions and enhanced efficiency.

Other SegmentsIn the field of petroleum product distribution, the operating environment

remained challenging in the year under review. In this setting, the Group

implemented aggressive marketing activities for a wide array of automobile-

related products, with a special focus on ENEOS brand goods. In our

real-estate operations, we enhanced our management and service systems

and improved existing facilities to increase tenant satisfaction levels.

Consolidated net sales in the Other business segment declined 27.3%,

to ¥58.5 billion, and operating income was down ¥1.8 billion, to ¥4.1 billion.

This result was primarily attributable to the removal of one consolidated sub-

sidiary from the scope of consolidation.

FINANCIAL POSITIONBalance SheetAt the end of the year under review, consolidated total assets were ¥4,385.5

billion, an increase of ¥169.9 billion from the end of the previous fiscal year.

This increase was principally attributable to the effect of the last day of the

fiscal year falling on a Japanese national holiday, which caused the payment

of excise tax payable for the fiscal year to be delayed.

Total liabilities as of March 31, 2007 were ¥3,053.5, an increase of ¥97.2

billion. Interest-bearing debt increased ¥84.5 billion to ¥1,297.1 billion due to

factors including higher operating capital caused by increasing crude oil prices.

Consolidated net assets totaled ¥1,332.0 billion, an increase of ¥72.7 billion

from a year earlier. (The change is measured from the total of minority interests

in consolidated subsidiaries and shareholders’ equity at the end of the

previous fiscal year.) This gain was the result of positive factors such as

consolidated net income exceeding negative factors such as year-end divi-

dends. As a result, the equity ratio was 27.7%. Net assets per share increased

¥54.02 to ¥829.64.

The ratio of net interest-bearing debt to equity was 84%.

Cash FlowsAs of the end of the year under review, cash and cash equivalents (hereinafter

referred to as “cash”) totaled ¥321.8 billion, an increase of ¥107.3 billion. The

cash flow movements and factors influencing them during the year under

review were as follows:

Net cash provided by operating activities amounted to ¥205.9 billion as

positive factors, such as income before income taxes and minority interests

(¥172.2 billion) and non-cash expenses, such as depreciation and amortiza-

tion (¥131.9 billion), exceeded negative factors, such as an increase in work-

ing capital. Also, the effect of the last day of the fiscal year falling on a Japanese

national holiday caused the payment of excise tax payable for the fiscal year

to be delayed.

Net cash used in investing activities amounted to ¥143.5 billion. This was

mainly due to investment in petrochemical product manufacturing equipment.

Net cash provided by financing activities amounted to ¥44.4 billion as positive

factors, such as the borrowing of working capital as a result of rising crude oil prices,

exceeded negative factors, such as dividend payments.

Commitment Line ContractsTo raise working capital efficiently, Nippon Oil has concluded a commitment line

contract with a syndicate of 5 banks with which it has transaction relationships.

This commitment line provides the Company with funding up to ¥150.0 billion

and US$200 million. There were no borrowings under this commitment line

during the fiscal year under review.

Capital Expenditures and Depreciation and AmortizationCapital expenditures for the fiscal year under review was ¥204.8 billion, which

mainly comprised strategic investment in the E&P and Petrochemical

businesses.

Depreciation and amortization expenses were down ¥3.2 billion

at ¥131.9 billion.

Research & Development ActivitiesR&D expenditures for fiscal 2006 were ¥12.6 billion. This primarily comprised

spending on the E&P and marketing businesses.

DIVIDENDSWe consider the return of profits to shareholders to be an important manage-

ment priority. To maintain stable dividend payments while increasing enter-

prise value, we will take into account the need to bolster internal reserves to

provide for investments targeting the realization of our growth strategies. With

consideration for such factors as business performance and balanced fund-

ing, we will work to increase dividends over the medium to long term. More-

over, in the implementation of our capital policy, we will take a flexible approach

to share buybacks.

In accordance with these policies, in April 2005 we purchased and retired

50 million shares of common stock at a total price of ¥38.5 billion. At the

same time, under the third consolidated medium-term management plan,

started in the previous fiscal year, we reevaluated the level of our dividends

and decided to target annual cash dividends of ¥12 per share. We plan

year-end dividends for the fiscal year under review of ¥6 per share. Therefore,

including the interim dividends, dividends applicable to the year will be ¥12

per share, the same as in the previous year.

BUSINESS RISKSThe Group faces a variety of risks that may play an important role in impacting

its financial condition, managerial performance and cash flow. The main risks

are outlined below:

1. Impact of fluctuating currency exchange rates (against the U.S. dollar)

and crude oil prices.

a. Impact on Inventory Assets

The Group mainly utilizes the cost method based on the gross average method

for valuating its inventory assets. With this valuation method, when crude oil

prices (in yen) rise above the unit price of inventory, inventory assets begin

pushing down the cost of goods sold (in this instance, cost of goods sold

increases slower than crude oil prices due to the low price of inventory), thus

making it a positive profitability factor.

Annual Report 2007 NIPPON OIL CORPORATION 61

On the other hand, when crude oil prices (in yen) fall below the unit

price of inventory, the valuation of inventory assets pushes up the cost of

goods sold, thus making it a negative profitability factor.

b. Impact on Exploration and Production of Oil and Natural Gas (E&P)

In the area of E&P, a rise in crude oil prices (in yen) is a positive factor for

profitability because it leads to an increase in revenues. On the other hand, a

drop in crude oil prices (in yen) is a negative factor for profitability because it

leads to a decrease in revenues.

2. Impact of fluctuations in demand and market conditions for petroleum

fuel and petrochemical products

The demand for petroleum products fluctuates depending on climate condi-

tions (such as an unseasonably cool summers or warm winters) and the

economic conditions of the time. Demand for petrochemical products will

fluctuate depending on economic growth and trends in Asian markets as export

dependence on Asia, in particular China, increases. Sales for the Nippon Oil

Group’s products will also be impacted by these fluctuations and as such,

demand trends are determined to be a profitability factor.

In addition, the domestic market for petroleum fuel products will fluctu-

ate as a result of the supply and demand environment for domestic petro-

leum fuel products, local reselling conditions and movements in the overseas

market for petroleum fuel products. Similarly, the market for petrochemical

products will fluctuate depending on raw naphtha prices and market condi-

tions in East Asia. Although the Nippon Oil Group revises sale prices to reflect

these fluctuations, such changes may be considered a profitability factor de-

pending on the market environment.

3. Impact of fluctuating interest rates

An increase in interest rates is considered a negative profitability factor because

it would increase interest expense on loans and other interest-bearing liabili-

ties and consequently worsen the balance of financial expenses. On the other

hand, a fall in interest rates is considered a positive profitability factor because

it would decrease interest expense on loans and other interest-bearing liabili-

ties and consequently improve the balance of financial expenses.

4. Risks arising from overseas businesses

The Group’s procurement, production, exporting and sales activities are car-

ried out not only in Japan, but on a global scale in areas such as North America,

Europe and Asia/Oceania. The Group believes that certain risks as outlined

below exist in its overseas activities.

a. Country risks – Political and economic turmoil in foreign countries and a freez-

ing of currency exchanges, a default on loans and others triggered by them

b. Social turmoil arising from strikes, terrorist activities, war, epidemics, etc.

c. Disasters arising out of an act of god

d. Restrictions arising from new regulations, such as import restrictions and

export trade management rules

The generation of such risks will hinder the Nippon Oil Group’s overseas

business activities and consequently, may lead to worsened financial performance.

5. Impact of trends in public investments and private capital expenditures

The Group’s construction segment relies heavily on contracted paving, civil

engineering, and construction projects. The profitability of this segment there-

fore fluctuates greatly on trends in the public investment and private capital

expenditures (including private residential investments) fields.

6. Impact of stricter environmental regulations

From the standpoint of global environmental protection, new regulations on

quality or the need to blend in biomass fuels may result in cost increases to

the Group’s operations. Costs may be in the form of capital expenditures into

refineries or an increase in variable costs.

7. Risks arising from information systems

Earthquakes, floods and other natural disasters may damage information sys-

tems and cease normal business operations. In a situation such as this, pro-

duction and sales activities of the Group will not only be compromised but it

may have a major negative impact on the business of vendors.

8. Operational risks associated with production facilities

The Group operates production facilities not only in Japan but also on a glo-

bal scale. Natural disasters or unforeseen events at any of these facilities that

leads to a ceasing of production may have a negative impact on the overall

financial performance of the Group.

Please note that although these risks contain items that may be forward-

looking in nature, they are based on information available to the Group at the

end of the fiscal year under review. In addition, the risks above should be not

considered a full list of risks that the Group may face in its operations.

Notes to Consolidated Financial StatementsNippon Oil Corporation and Consolidated SubsidiariesMarch 31, 2007

1 Significant Accounting Policies

(a) Basis of preparation

The Company and its domestic consolidated subsidiaries maintain their accounting records and prepare their financial statements in accordance with accounting

principles generally accepted in Japan, and its overseas consolidated subsidiaries maintain their books of account in conformity with those of their countries of

domicile. The accompanying consolidated financial statements have been compiled from the accounts prepared by the Company in accordance with the provi-

sions set forth in the Securities and Exchange Law of Japan and in conformity with accounting principles generally accepted in Japan, which are different in certain

respects as to the application and disclosure requirements of International Financial Reporting Standards.

In addition, the notes to the consolidated financial statements include information which is not required under accounting principles generally accepted in

Japan but is presented herein as additional information.

As permitted under the Securities and Exchange Law of Japan, amounts of less than one million yen have been omitted. As a result, the totals shown in the

accompanying consolidated financial statements (both in yen and in U.S. dollars) do not necessarily agree with the sums of the individual amounts.

Certain amounts in the prior year’s financial statements have been reclassified to conform to the current year’s presentation.

(b) Principles of consolidation and accounting for investments in unconsolidated subsidiaries and affiliates

The accompanying consolidated financial statements include the accounts of the Company and all its significant subsidiaries. Investments in certain unconsoli-

dated subsidiaries and significant affiliates are accounted for by the equity method. All significant intercompany balances and transactions have been eliminated

in consolidation.

The excess of cost over the underlying equity in net assets at the dates of acquisition of the major consolidated subsidiaries is amortized by the straight-line

method over 5 years.

Investments in unconsolidated subsidiaries and affiliates not accounted for by the equity method are stated at cost or less. Where there has been a permanent

decline in the value of the investments, the Company has written them down to reflect the impairment.

(c) Foreign currency translation

Monetary assets and liabilities denominated in foreign currencies included in the current and noncurrent foreign currency accounts of the Company, of its

domestic consolidated subsidiaries and of its affiliates accounted for by the equity method have been translated into yen at the rates of exchange in effect at the

year end. Translation differences are charged or credited to income.

The accounts of the overseas consolidated subsidiaries are translated into yen as follows: all assets, liabilities and retained earnings at the end of the year and

items in the consolidated statements of income including net income, at the rate of exchange in effect at the year end; capital stock, at historical rates; and cash

dividends paid, at the rate of exchange in effect when paid. Translation differences arising from the balance sheet items are included in shareholders’ equity, and

those arising from minority interests in consolidated subsidiaries are reflected as translation adjustments.

(d) Cash equivalents

The Company and its consolidated subsidiaries substantially consider all highly liquid investments with a maturity of three months or less when purchased to be

cash equivalents.

(e) Securities

The accounting standard applicable to securities requires that all securities be classified into three categories: trading, held-to-maturity securities or other. Held-to-

maturity securities have been stated at their amortized cost. Marketable securities classified as other securities have been stated at fair value with any changes in

unrealized holding gain or loss, net of the applicable income taxes, included directly in shareholders’ equity. Non-marketable securities classified as other securities

have been stated at cost. Cost of securities sold has been determined by the moving average method.

(f) Property, plant and equipment and depreciation

Property, plant and equipment is stated at cost.

Depreciation of property, plant and equipment is computed principally by the straight-line method for buildings, and by the declining-balance method for

other property, plant and equipment, over the estimated useful lives of the respective assets.

Significant renewals and improvements are capitalized at cost. Maintenance and repairs are charged to income.

FINAN

CIAL SECTION

NIPPON OIL CORPORATION Annual Report 200768

(g) Inventories

Inventories are stated mainly at cost determined principally by the average method.

(h) Accounting procedure for exploration and development investments

Expenditures relating to exploration and development under certain agreements are capitalized as assets and recovered in accordance with the terms of the

respective agreements.

(i) Leases

Noncancelable leases are accounted for primarily as operating leases (whether such leases are classified as operating or finance leases) except that leases which

stipulate the transfer of ownership of the leased assets to the lessee are accounted for as finance leases.

(j) Retirement benefits

Accrued retirement benefits are stated principally at the amount calculated based on the present value of the retirement benefit obligation and the fair value of the

pension plan assets, as adjusted for unrecognized actuarial gain or loss, and unrecognized prior service cost. Prior service cost is amortized as incurred by the

straight-line method, principally over 5 years. Actuarial gain or loss is amortized commencing in the subsequent period by the straight-line method, principally over

5 years.

(k) Income taxes

Deferred income taxes are determined based on the differences between the amounts determined for financial reporting purposes and the tax bases of the assets

and liabilities and are measured using the enacted tax rates and laws which will be in effect when the differences are expected to reverse.

(l) Reserve for inspection of oil tanks, machinery and equipment, and vessels

The Company and its domestic consolidated subsidiaries are required periodically to inspect their oil tanks, the machinery and equipment of their oil refineries,

and their vessels. A reserve for the inspection of oil tanks, machinery and equipment, and vessels is provided for the current portion of the estimated total cost for

such work.

(m) Accrued estimated cost for abandonment of wells

The accrued estimated cost of abandonment of wells is provided to cover the costs to be incurred upon the abandonment of wells at an estimated amount

allocated over a scheduled period based on consolidated subsidiaries’ plans for the abandonment of such wells.

(n) Accounting standard for presentation of net assets in the balance sheet

Effective the year ended March 31, 2007, the Company and its domestic consolidated subsidiaries adopted new accounting standards, “Accounting Standard for

Presentation of Net Assets in the Balance Sheet” (“Statement No. 5” issued by the Accounting Standards Board of Japan on December 9, 2005), and “the

Implementation Guidance for the Accounting Standard for Presentation of Net Assets in the Balance Sheet” (“the Financial Accounting Standard Implementation

Guidance No. 8” issued by the Accounting Standards Board of Japan on December 9, 2005), (collectively, the “New Accounting Standards”).

In addition, effective the year ended March 31, 2007, the Company and its domestic consolidated subsidiaries are required to prepare consolidated state-

ments of changes in net assets instead of consolidated statements of shareholders’ equity. In this connection, the previously reported consolidated balance sheet

as of March 31, 2006 has been restated to conform to the presentation and disclosure of the consolidated financial statements for the year ended March 31, 2007.

Total shareholders’ equity under the previous method of presentation at March 31, 2007, which comprised common stock, capital surplus, retained earnings,

unrealized gain on securities, net of deferred income taxes, and translation adjustments, amounted to ¥1,192,838 million ($10,108,797 thousand).

(o) Research and development costs

Research and development costs are charged to income when incurred.

(p) Derivatives

Derivatives are stated at fair value with any changes in unrealized gain or loss charged or credited to income, except for those which meet the criteria for deferral

hedge accounting under which unrealized gain or loss is deferred as an asset or a liability. Receivables and payables hedged by qualified forward foreign exchange

contracts and currency swaps are translated at the corresponding contract rates.

Annual Report 2007 NIPPON OIL CORPORATION 69

(q) Amounts per share

Basic net income per share for the years ended March 31, 2007 and 2006 has been computed based on the net income attributable to shareholders of common

stock and the weighted-average number of shares of common stock outstanding during the year.

2 U.S. Dollar Amounts

The translation of yen amounts into U.S. dollar amounts is included solely for convenience and has been made, as a matter of arithmetic computation only, at

¥118=U.S.$1.00, the approximate rate of exchange in effect on March 31, 2007. The translation should not be construed as a representation that yen have been,

could have been, or could in the future be, converted into U.S. dollars at that or any other rate.

5 Loss on Impairment of Fixed Assets

Recognition of impairment losses on fixed assets for the years ended March 31, 2007 and 2006 resulted primarily from a significant decrease in the market value

Report of Independent Auditors

The Board of Directors

Nippon Oil Corporation

We have audited the accompanying consolidated balance sheets of Nippon Oil Corporation and consolidated subsidiaries as of March 31, 2007 and 2006, and the

related consolidated statements of income, shareholders’ equity, and cash flows for the years then ended, all expressed in yen. These financial statements are the

responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in Japan. Those standards require that we plan and perform the audit to obtain

reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting

the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by

management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Nippon Oil Corporation and

consolidated subsidiaries at March 31, 2007 and 2006, and the consolidated results of their operations and their cash flows for the years then ended in conformity

with accounting principles generally accepted in Japan.

The U.S. dollar amounts in the accompanying consolidated financial statements with respect to the year ended March 31, 2007 are presented solely for

convenience. Our audit also included the translation of yen amounts into U.S. dollar amounts and, in our opinion, such translation has been made on the

basis described in Note 2.
