Hachinohe Domain
was a tozama feudal domain of Edo period Japan It is located in Mutsu Province, in northern Honshū. The domain was centered at Hachinohe Castle, located in the center of what is now the city of Hachinohe in Aomori Prefecture. History On the death of the 2nd daimyō of Morioka Domain, Nanbu Shigenao while under house arrest in Edo, the Tokugawa shogunate intervened in the succession and by order of Shōgun Tokugawa Ietsuna divided the 100,000 koku domain into Morioka Domain (80,000 koku) and Hachinohe Domain (20,000 koku). Hachinohe Domain thus had a somewhat ambiguous status in that it is sometimes regarded as a sub-domain of Morioka Domain although it had not been created by the Nanbu clan. It was also subject to the normal sankin kotai regulations, and was allowed to maintain a castle (which was normally permitted only to independent domains). During official investigations into the untimely deaths of its first two daimyō. Morioka Domain insisted that Hachinohe was not part of their territory and therefore not their responsibility. Furthermore, in 1812, when the domain's residence in Edo burned down, and the 10th daimyō of Morioka Domain, Nanbu Toshitaka, refused to assist with its rebuilding, citing the "independence"
