The area of present-day Iwaizumi was part of ancient Mutsu Province, dominated by the Nambu clan during the Edo period, who ruled Morioka Domain under the Tokugawa shogunate. With the Meiji period establishment of the modern municipalities system, the village of Iwaizumi was created within Kitahei District on April 1, 1889. Kitahei, Nakahei and Higashihei Districts were all merged into Minamihei District on March 29, 1896.

Iwaizumi was elevated to town status on August 1, 1922. On September 30, 1956, Imaizumi annexed the neighboring villages of Akka, Ugei, Okawa and Omoto and on April 1, 1957, annexed the village of Kogawa to reach is present borders.

In August 2016, typhoon Lionrock hit the town with strong Winds and heavy Rain that caused Landslides and Flooding. 19 people died, including 9 people drowned in a nursing home after a river burst its banks.
