Soils developed on each terraces in the environs of Minokamo Basin, were surveyed and classified into three genetic soil types as follows; 1) Yellow Brown Forest Soils: Developed on the lower and upper terraces, as well as on the hills composed of Plio-Pleistocene (?) Told Sand and Gravel Bed. 2) Relict Red Soils: Found on the hills composed of Miocene Nakamura Group and on flat surfaces of upper terraces. 3) Kuroboku Soils: Mainly developed on the middle terraces and nearly whole area is used as paddy fields.
