Small mammals were surveyed in the north central region of the Ina Mountains and around the summit of Mt. Oikeyama in the Akaishi Mountain Range, central Honshu, Japan. In total, 17 adult individuals of either Eothenomys smithii, Apodemus speciosus, or A. argenteus, were collected from the Hinoki plantations (1,090–1,120 m altitude) in the former, and 15 adult individuals of either Dymecodon pilirostris, Urtorichus talpoides, E. smithii, Microtus montebelli, A. speciosus, or A. argenteus were collected from the subalpine coniferous forests and larch plantations (1,750–1,820 m altitude) in the latter. The distributions of these species considering previous studies, closely related species in nearby mountainous areas, and present records of each species seem to occur according to not only vegetation and altitudes but also artificial factors such as plantations, or colonization histories depending on geographical features in these areas.
