Taira no Hidemori (Tozawa Hidemori)

Genealogies name Taira no Hidemori, later called Tozawa Hidemori, as founder of the Tozawa clan and a son of Taira no Michimasa of the Kammu Heike. He first served Kiso Yoshinaka, then withdrew to the Shizukuishi manor in Iwate district, Mutsu.

In 1185 he submitted to Minamoto no Yoritomo, fought at Yashima and in the Ōshū campaign, and was enfeoffed with lands in Shizukuishi, taking the name Tozawa from his settlement there. Modern scholars suspect he was really a local retainer of the Northern Fujiwara.
