[3] During the Edo period, all of Izu Province was tenryō territory under direct control of the Tokugawa shogunate, and the area now comprising Higashiizu Town consisted of 5 villages (Inatori, Naramoto, Shirata, Katase, and Ōkawa).

With the establishment of the modern municipalities system in the early Meiji period in 1889, the area was reorganized into two villages (Inatori and Jōtō) with Kamo District.

The economy of Higashiizu is dominated by tourism centered on the hot spring resort industry, and by commercial fishing.
