History

The area of Senboku District was formerly part of Dewa Province, and was originally created out of Hiraka District in the year 870. Dewa Province was divided into the provinces of Ugo Province and Uzen Province following the Meiji Restoration on January 19, 1869, with the area of Semboku becoming part of Ugo Province. At the time, the area consisted of one town (Kakunodate) and 181 villages formerly under the control of Kubota Domain. Akita Prefecture was founded on December 13, 1871.
