Tsugaru Tsugumichi

was the fourth and final daimyō of Kuroishi Domain in northern Mutsu Province, Honshū, Japan (modern-day Aomori Prefecture). His courtesy title was Shikibu-no-shō, and his Court rank under the Tokugawa shogunate was Junior Fifth Rank, Lower Grade.

Biography Tsugaru Tsugumichi was the son of Tsugaru Yukitomo, from a branch line of the Tsugaru clan, and was adopted by the 3rd daimyō of Kuroishi, Tsugaru Tsuguyasu, as official heir due to the lack of a male descendant on Tsuguyasu's death in 1851. He changed his name at the time from Tsugaru Tomozumi to Tsugaru Tsugumichi.

Tsugumichi became daimyō during the turbulent Bakumatsu period, during which time the Tsugaru clan first sided with the pro-imperial forces of Satchō Alliance, and attacked nearby Shōnai Domain. However, the Tsugaru soon switched course, and briefly joined the Ōuetsu Reppan Dōmei. However, for reasons yet unclear, the Tsugaru backed out of the alliance and re-joined the imperial cause after a few months, participating in several battles in the Imperial cause during the Boshin War, notably that of the Battle of Noheji, and Battle of Hakodate.
