History
During the Edo period, all of Izu Province was tenryō territory under direct control of the Tokugawa shogunate, and the area now comprising Minamiizu Town consisted of 25 villages. With the establishment of the modern municipalities system of the early Meiji period in 1889, the area was reorganized into six villages (Minamizaka, Minaminaka, Minamikami, Mizaka, Mihama and Chikuma) within Kamo District. The town of Minamiizu was formed in July 1955 through the merger of these six villages.
