Kōriyama originated as a regional governmental center in the Nara period, when the area was on the frontier of Yamato settlement of the Tohoku region. The surrounding area developed into shōen controlled by various samurai clans in the Heian and Kamakura periods. Nearby centers, such as Nihonmatsu developed into castle towns, Kōriyama remained as a commercial center and thrived as a post town because of its importance as a traffic focal point into the Edo period. As a major military equipment production center, Koriyama was subject to three large-scale air raids during WW2.
Kōriyama city is called the "commercial capital in Fukushima".
