久保田藩
The area of present-day Happō was part of ancient Dewa Province, dominated by the Satake clan during the Edo period, who ruled Kubota Domain under the Tokugawa shogunate. The modern town of Happō was created on March 27, 2006, by merging the village of Minehama, and the town of Hachimori, both from Yamamoto District.
