Daihōji

The Daihōji were a warrior family descended from the Mutō, who entered the Shōnai region of Dewa Province as estate stewards. They took their name from Daihōji Castle and later ruled as local deputies; in 1463 Daihōji Atsuuji visited Kyoto and paid homage to Shogun Ashikaga Yoshimasa.

Daihōji Yoshiuji restored the family's power in Shōnai, but in 1583 a retainer rebelled and surrounded his castle, leading to his death. His successor Yoshikatsu recovered Shōnai with his father Honjō Shigenaga in 1588, but lost his domain in 1591 and entered Uesugi service.
