The area of Kihō was part of the holdings of the Kii Tokugawa clan, administered as part of the Kii-Shingū Domain in the Edo period. After the Meiji restoration, the area was organized into the villages of Ida, Mifune, and Onodani within Minamimuro District of Mie Prefecture. The town of Kihō was established on October 31, 1951 by the merger of these three villages. On January 10, 2006, the village of Udono – which was part of the Minamimuro District until then – was merged into Kihō.
