List of power stations in Japan

Overview
Japan runs a large number of power stations across the country to generate electricity. The list includes nuclear plants, fossil-fuel plants (coal, oil, and natural gas), hydroelectric facilities (including pumped-storage), and renewable sources like solar and wind. Plants vary in size, fuel type, ownership, location, and current status (operating, suspended, under construction, decommissioned, etc.).

Notable power stations (highlights by fuel)

Nuclear
- Kashiwazaki-Kariwa Nuclear Power Plant (Niigata): one of the largest, with a total capacity over 8,000 MW, currently suspended.
- Fukushima Daiichi and Fukushima Daini Nuclear Power Plants (Fukushima): very large facilities; Fukushima I is in cold shutdown and planned for decommissioning; Fukushima II is also in cold shutdown.
- Ikata Nuclear Power Plant (Ehime): operational and providing power.
- Takahama Nuclear Power Plant (Fukui): operational.
- Hamaoka Nuclear Power Plant (Shizuoka): suspended.
- Ōi Nuclear Power Plant (Fukui): suspended.
- Genkai Nuclear Power Plant (Saga): operational (as listed in some sources) or suspended depending on time.
- Tomari Nuclear Power Plant (Hokkaidō): shut down for maintenance.

Coal, oil, and gas (fossil fuels)
- Hekinan Thermal Power Station (Aichi): coal-fired, among the largest in Japan.
- Matsuura and Maizuru (various prefectures): coal-fired plants with several hundred to a few thousand MW.
- Oi, Kashima, Chiba, Futtsu, Sodegaura, Yokohama, and Chita/Yokkaichi series: large gas or oil/gas-fired plants scattered across the Tokyo, Chubu, and Kansai regions.
- Atsumi (Aichi) and Tomakomai (Hokkaidō) plants: oil-fired facilities of significant size.
- Tomakomai and other coastal plants illustrate Japan’s use of fossil fuels to complement nuclear and renewables.

Hydroelectric and pumped storage
- Kurobe Dam and other major hydro plants: important contributors to peak and base load.
- Pumped-storage sites such as Kannagawa (under construction in some sources), Kazunogawa, Matanoagawa, Maki, and several others across Nagano, Yamanashi, Niigata, and nearby prefectures.
- Sagami Dam, Tashiro Dam, and many smaller hydro plants provide seasonal and daily balancing.

Renewables
- Solar: Setouchi Kirei Mega Solar Plant (Okayama), Eurus Rokkasho Solar Park (Aomori), and many large and small solar farms nationwide (numerous plants in 10–200+ MW range, plus many smaller sites).
- Wind: multiple onshore wind farms (for example, Aoyama Plateau Wind Farm with tens of MW, plus many others in coastal or elevated areas).
- Offshore wind and other renewables are present but less numerous than solar and onshore wind in Japan’s current mix.

Former power stations
- Senju Thermal Power Station (no longer in operation)

Quick notes
- The list includes details such as station name, location (prefecture), capacity (MW), fuel type (Nuclear, Coal, Gas, Oil, Hydroelectric, Solar, Wind, etc.), year, and current status (e.g., Operational, Suspended, Under construction, Withdrawn, Cold shutdown, Decommissioned).
- Many plants have complex histories, with some reactors restarted or retired, and statuses that change over time.
