Mizusawa Domain
The Mizusawa Domain was a feudal domain in Mutsu Province of Japan during the Edo period. It was a subdomain of the Sendai Domain. Sometimes it was suggested that the domain be called "Naka-Tsuyama han". The domain as a separate entity was ultimately short-lived, eventually being reabsorbed into Sendai territory.
Early during the rule of the Date clan, the area was under the care of Shiroishi Munezane.
Among those originally from this domain are Rangaku scholar Takano Chōei, politician Gotō Shimpei and admiral Saitō Makoto.
