Tozawa

The Tozawa were a warrior family whose power was rooted in the Senboku region of Dewa, and whose later base was at Kakunodate.

In 1590 Tozawa Moriyasu joined Toyotomi Hideyoshi’s Odawara campaign but died there of illness. His son Masamori supported Tokugawa Ieyasu in 1600 and was transferred to Hitachi. After the Mogami were dispossessed in 1622, Masamori received Shinjō in Dewa, where his descendants ruled throughout the Edo period.
