Tomioka (富岡町, Tomioka-machi) is a town located in Fukushima Prefecture. As of 1 August 2020, the city had an estimated population of 1,489 in 5578 households and a population density of 21,8 persons per km²; the current actual resident population is considerably smaller than in 2010. Tomioka is located on the Pacific Ocean coastline of central Fukushima. It is the location of the Fukushima Daiichi Nuclear Power Plant, owned by the Tokyo Electric Power Company. The town of Tomioka is divided into two central districts, each with its train station. To the south is Tomioka, which is the main area. To the north, on top of the hill, is Yonomori, a smaller and much newer neighbourhood. The two regions operate under one government, but physical distance makes them feel like two separate towns. Tomioka was severely affected by the Fukushima Daiichi nuclear disaster and the 2011 Tōhoku earthquake and tsunami on 11 March 2011. Besides sustaining considerable damage from the quake, and the tsunami (which devastated the coastal area), the town was evacuated en masse on the morning of 12 March as it is located well within the 20-kilometre exclusion radius around the damaged Fukushima Daiichi nuclear power plant.
