History

During the late Heian and Kamakura periods, the town of Nirayama within the current borders of Izunokuni was the home of the Later Hōjō clan, who dominated Japanese politics in the 12th century. A castle was established at Nirayama by Ise Moritoki in 1493. During the Edo period, most of Izu Province was tenryō territory under direct control of the Tokugawa shogunate, who ruled Izu and parts of eastern Suruga Province from a daikansho established at Nirayama. After the Meiji Restoration, the area became the short-lived Nirayama Prefecture, which was merged into the equally short-lived Ashigara Prefecture in 1871. From 1876, the area has been part of Shizuoka Prefecture. During the cadastral reform of 1886, the area was reorganized into several villages under Kimisawa District, which was with Tagata District in 1896. In 1934, the village of Izunagaoka was elevated to town status, followed by Ōhito in 1940, and Nirayama in 1962.

The city of Izunokuni was created on April 1, 2005 from the merger of the towns of Izunagaoka, Nirayama and Ōhito (all from Tagata District).
