The Fukushima II Nuclear Power Plant is a nuclear power plant located in the town of Naraha and Tomioka in the Futaba District of Fukushima Prefecture. Like Fukushima I, it is run by The Tokyo Electric Power Company.

Unit Type First Criticality Electric Power Installation costs (yen/kW)
Fukushima II - 1 BWR 4/20/1982 1100 MW 25
Fukushima II - 2 BWR 2/3/1984 1100 MW 23
Fukushima II - 3 BWR 6/21/1985 1100 MW 29
Fukushima II - 4 BWR 8/25/1987 1100 MW 25

In January 1989, an impeller blade on one of the reactor coolant pumps in Unit 3 broke at a weld, causing a large amount of metal mass to flow throughout the primary loop. As a result, the reactor was shut down for a considerably long time, making this one of the most serious accidents at the site.

In March 2011, nuclear reactors were automatically shut down at the Fukushima No. 1 and Fukushima No. 2 plants after the biggest-magnitude quake in the country's modern history. Tokyo Electric on March 12 reported that the cooling system for three reactors (nrs 1, 2 and 4) at the plant had topped 100 °C between 5:30 and 6:10 JST, less than one hour after the start of additional cooling with condensate water, and that the "pressure suppression function was lost".
