伊豆国
During the Edo period, most of Izu Province was "tenryō" territory under direct control of the Tokugawa shogunate, although portions near modern Shuzenji were under the control of the Ōkubo clan of Ogino-Yamanaka Domain. During the establishment of the modern municipalities system in the early Meiji period in 1889, the area was reorganized into several villages under Kimisawa District, Shizuoka Prefecture. Kimisawa District merged with Tagata District in 1896.
