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.
After the Meiji Restoration, with the abolition of the han system, Tsugumichi was appointed Imperial Governor of Kuroishi from 1869 to 1871, at which time the territory was absorbed into the new Aomori Prefecture. He relocated to Tokyo, and with the establishment of the "kazoku" peerage system in 1882, he was awarded with the title of "shishaku" (viscount). He became a member of the House of Peers in 1890. In his later years, he was noted for his "waka" poems. On his death, he was posthumously granted Third court rank. His grave is at the Yanaka Cemetery in Taitō-ku, Tokyo.
