Nanbu clan

The Nanbu kamon.

The Nanbu of northern Mutsu province were descended from the Takeda of Kai. During the Sengoku Period they became powerful in northern Mutsu, competing with the Akita, Tozawa, and others for territory. Nanbu Yasunobu destroyed the Namioka clan in 1523 and under the leadership of his son Harumasa the family expanded their power greatly. They later submitted to Toyotomi Hideyoshi, supported the Tokugawa during the Sekigahara Campaign, and resided at Morioka castle until the end of the Edo Period.
