Hachinohe Domain

Hachinohe Domain (八戸藩, Hachinohe-han^?) was a tozama feudal domain of Edo period Japan It is located in Mutsu Province, Honshū. Its territory included 41 villages in Sannohe District, 38 villages in Kunohe District, and 4 villages in Shiwa District, with a total revenue of 22,000 koku. The domain was centered at Hachinohe Castle, located in the center of what is now the city of Hachinohe in Aomori Prefecture.

Hachinohe Domain had a somewhat ambiguous status in that it was regarded as a sub-domain of Morioka Domain and ruled by a branch of the Nambu clan, although it had been established by order of the Tokugawa Shogunate, was subject to the sankin kotai regulations, and was allowed to maintain a castle (which was permitted only to independent domains). Its status was clarified in 1812, when the domain's residence in Edo burned down, and the 10th daimyō of Morioka Domain, Nambu Toshitaka, refused to assist with its rebuilding, citing the "independence" of Hachinohe.
