Ōnuma

Ōnuma lies in the Aizu country of western Mutsu, where mountain valleys open towards the Aizu basin. Its old settlements include Takada, home to Isasumi Shrine, one of the principal shrines of the province. The district took shape from the older Aizu district in early times. Woodland and mountain slopes surround the cultivated land, giving way to the broader basin toward the east.
