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.
