關東平原
Located in the northwestern portion of the Kantō Plain, the village stretched from the summit of Mount Akagi to the bottom. At the summit of Mount Akagi, there are two lakes, Ōnuma and Konuma, caldera lakes. Alpine plants such as Asian skunk cabbages grow in the marshland. The northern portion of the village was mainly covered by forests without many human dwellings, while the southern portion was flat with farmland.
