Kira Mitsuie

Kira Mitsuie was the second Ōshū kanrei and eldest son of Kira Sadaie. When his father took up the northern post in 1345, his family moved to Mutsu and based themselves at Taga Castle. In the Kannō Disturbance Mitsuie backed Ashikaga Tadayoshi and helped destroy his co-kanrei Hatakeyama Kuniuji, becoming sole Ōshū kanrei.

He retook Taga Castle from a Southern Court army in 1352 and captured Utsumine in 1353. Driven out in 1354, he fled to the Date clan and recovered the castle that July. His last surviving documents date to 1356.
