Shichinohe Domain

Shichinohe Domain (七戸藩, Shichinohe-han^?) was a tozama feudal domain of Edo period　Japan, located in Mutsu Province, Honshū. Its territory was roughly equivalent to the areas covered by modern-day town of Shichinohe in Aomori Prefecture. It was also called the Morioka Nitta Domain (盛岡新田藩^?).

Shichinohe Domain was a sub-domain of Morioka Domain, founded in 1819 for Nambu Nobuchika, the 5th generation descendent of the Nambu Masanobu, younger brother of the 5th daimyō of Morioka domain. Nambu Yukinobu. Masanobu had received lands with a value of 5,000 koku in what later became Ninohe District. His 5th generation descendant was awarded an additional 6000 koku by the 11th daimyō of Morioka domain, which put his revenues over the 10,000 koku mark to become a daimyo. The 11,000 koku domain existed largely on paper, as its daimyō lived in Edo permanently, and ruled the domain via a karō.

As a subsidiary domain, the domain did not have a proper castle, but was governed out of a Jin'ya, although its rulers had the honor of being styled as castellan.
