Summary
The day roosts and foraging areas of the common Japanese pipistrelle bat, P. abramus, were investigated
in the Imperial Palace, Tokyo, Japan. Since the six roosts are observed at Kikyo-mon Gate and
Sakashita-mon Gate, we demonstrate that the pipistrelles often use the roost also within the Imperial
Palace. The openings of the Japanese traditional roof tile may be suitable for the roost of bat in the Palace.
The results of the line census point out that the pipistrelles do not use the whole area of the Imperial Palace,
however, prefer the areas along the moats such as the regions near Kikyo and Ote Gates. From the track
data of an individual with chemiluminescent tag, we conclude that the pipistrelle use the roots along the
paved road and Hamaguri-bori Moat in the foraging areas. The findings indicate the nocturnal foraging
activity in the Imperial Palace, and provide us with the fundamental data on the behavior of the common
Japanese pipistrelle within the large city.
