Ōshū Kaidō
The area of present-day Hanamaki was part of ancient Mutsu Province, and has been settled since at least the Jōmon period. During the Sengoku period, the area was dominated by various samurai clans before coming under the control of the Nambu clan during the Edo period, who ruled Morioka Domain under the Tokugawa shogunate. The town developed as a post station on the Ōshū Kaidō highway during the Edo period.
