Morioka Domain
was the 1st "daimyō" of Shichinohe Domain. He was the eldest son of Nanbu Nobuyoshi, a 5000 "koku" "hatamoto" of Morioka Domain. In December 1819, he received additional territories from his uncle, Nanbu Toshitaka, bringing his total past 10,000 "koku" and received elevation to the rank of "daimyō". His courtesy title was "Harima-no-kami", and his Court rank was Junior Fifth Rank, Lower Grade. Due to the death of the first Nanbu Toshimochi in 1820, he was called upon to assist in the governing of Morioka Domain. He was received in formal audience by "shōgun" Tokugawa Ienari on November 15, 1821 and confirmed in his title, but died only a few days later.
