Tokugawa Ietsuna
After his death in Edo in 1664, the Tokugawa shogunate intervened, and by order of Shogun Tokugawa Ietsuna appointed his younger brother Shichinohe Shigenobu as the next "daimyō", with the son of Hotta Masamori reduced to "hatamoto" status. The "kokudaka" of Morioka Domain was also reduced by 20,000 "koku" to 80,000 "koku", with the creation of Hachinohe Domain for Shigenao’s third brother, Nakasato Naoyoshi, who was renamed Nanbu Naofusa.
