01 · SafetySafety and practical guidance for Kōriyama
Kōriyama is a core city located in Fukushima Prefecture, Japan, functioning as a commercial center and the third largest conurbation in the Tōhoku region. The municipality operates within the Asia/Tokyo timezone and covers a population of 327,692 residents.
Historical turning points have profoundly reshaped Kōriyama, transitioning from an ancient regional governmental center and a post town along traffic routes into a modern agricultural and industrial hub. The Meiji period brought dispossessed samurai to reclaim undeveloped lands, while hydroelectric power spurred local industry. During World War II, its role as a military equipment production center led to heavy American air raids. Decades later, the Great East Japan Earthquake on March 11, 2011, caused structural damage, though Kōriyama remained outside the mandatory evacuation zone established after the Fukushima Daiichi nuclear disaster, subsequently absorbing many displaced residents who relocated from the affected zones.

04 · OverviewKōriyama, in brief
Kōriyama is a city situated in Fukushima Prefecture, Japan. Functioning as a commercial center for the prefecture, it is the third largest conurbation in the Tōhoku region and holds a population of 327,692.
Historically, the settlement originated as a regional governmental center during the Nara period along the frontier of Yamato settlement in the Tōhoku region. By the Edo period, Kōriyama functioned as a traffic focal point and thrived as a post town within the territory of Nihonmatsu Domain. A historical turning point for the region arrived in the early Meiji period, when dispossessed samurai were assigned undeveloped lands in the area to reclaim. This resettlement spurred population growth and transformed the region into an agricultural center, while the relative abundance of hydroelectric power further stimulated the development of local industry.
The municipal status of Kōriyama shifted significantly on September 1, 1924, when it was raised from town to city status following the annexation of neighboring Odawara Village. Kuwano Village was subsequently annexed on June 1, 1925. During the 1930s, the city emerged as a noted center for military equipment production, making it a target for American bombers during World War II and subjecting it to three large-scale air raids. Further territorial expansions occurred between 1954 and 1955 through the annexation of Otsuki and portions of Tomita and Iwae, followed by the annexation of Nishida and Nakata in 1965. In 1997, Kōriyama received core city designation, granting it increased autonomy from national and prefectural governments.
Geographically, Kōriyama lies in the center of the Nakadōri region, bordered by the Adatara Mountains to the north, Lake Inawashiro to the west, and the Abukuma Highlands to the east, with the Abukuma River flowing directly through downtown. On March 11, 2011, the Great East Japan Earthquake caused damage to the city, though it remained outside the mandatory evacuation zone established after the Fukushima Daiichi nuclear disaster, leading many evacuees to relocate there. Later, on July 30, 2020, a restaurant explosion damaged an area spanning several hundred meters.
