Kōriyama originated as a regional governmental center in the Nara period, when the area was on the frontier of Yamato settlement of the Tōhoku 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 and was part of the territory of Nihonmatsu Domain.
With the establishment of the modern municipalities system on April 1, 1889, the town of Kōriyama was established within Asaka District. In the early Meiji period, many dispossessed samurai were assigned undeveloped lands in the area to reclaim and as a result, the population grew and region developed into an agricultural center. The relative abundance of hydroelectric power also helped with the development of local industry.
Kōriyama was raised from town to city status on September 1, 1924 with the annexation of neighboring Odawara Village. Kuwano Village was likewise annexed on June 1, 1925. During the 1930s, Kōriyama was noted a center for military equipment production. It was thus a target for American bombers during World War II, and the city was subject to three large-scale air raids during the war.
From 1954 to 1955, Kōriyama expanded by annexing the town of Otsuki and portions of the villages of Tomita and Iwae, and in 1965 annexed the villages of Nishida and Nakata. In 1997, the city received core city designation, giving it increased autonomy from national and prefectural governments.
On March 11, 2011, the Great East Japan Earthquake caused damage, but Kōriyama is located outside of the mandatory evacuation zone set by the Japanese government after the Fukushima Daiichi nuclear disaster. Many people from the evacuation zone relocated to Kōriyama. On 30 July 2020, a shabu-shabu restaurant exploded, damaging an area spanning several hundred meters.[7]
Kōriyama has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 38 members. The city contributes nine members to the Fukushima Prefectural Assembly. In terms of national politics, Kōriyama is part of the Fukushima 2nd Electoral District, which includes neighbouring Nihonmatsu, Motomiya and Adachi District.
