The following is a list of Japanese nuclear power plants. After the Fukushima Daiichi nuclear disaster, all 17 major plants were shut down. As of 2022, only 6 out of 17 major nuclear power plants operate in the country, operated by the Kyushu Electric Power (Kyuden), Shikoku Electric Power Company (Yonden) and Kansai Electric Power Company (Kanden).
