This investigation was carried out in forests situated at altitudes ranging from 560 to 680 meters on the eastern side of Mt. Shirataka (alt. 994m). Two types of plantation, a young Japanese cedar (Cryptomeria japonica D. DON.) and a young Japanese red pine (Pinus densiflora SIEB. et ZUCC.), were selected for the investigation. The floor plants of both plantations consist of Japanese pampas grass (Miscanthus sinensis ANDERSS.), weeds, young broad-leaved deciduous trees, bamboo grass (Sasa paniculata MAKINO et SHIBATA), or arrowroot (Pueraria Thunbergiana BENTH.). The collection of voles and mice at 8 different plots were made by means of snap trapping with sweet potato as the bait. Microtus montebelli montebelli was abundant in the weeds of the floor plants of both plantations. Clethrionomys rufocanus andersoni was frequently found in the floor weeds of the young Japanese cedar plantation. Apodemus speciosus speciosus was also very common in this type of plantation, especially that having young broad-leaved deciduous trees on its floor. Apodemus geisha geisha was also found frequently in the same plot.
