Tohoku Electric Power Co., Inc. (東北電力株式会社, Tōhoku Denryoku Kabushiki Kaisha ) is an electric utility, servicing 7.6 million individual and corporate customers in six prefectures in Tōhoku region plus Niigata Prefecture. It provides electricity at 100 V, 50 Hz, though some area use 60 Hz.


Tohoku Electric Power is the fourth-largest electric utility in Japan in terms of revenue, behind TEPCO, KEPCO and Chubu Electric Power.



On 11 March 2011, several nuclear reactors in Japan were badly damaged by the 2011 Tōhoku earthquake and tsunami. In the Onagawa Nuclear Power Plant a fire broke out in the turbine section of the plant. [1]

In order to make up for the loss of electricity from the damaged reactor plant, Tohoku announced it would restart a mothballed natural gas power plant. The liquefied natural gas and oil-fired No. 1 unit at the Higashi Niigata plant in Niigata prefecture has a 350-megawatt capacity and could be in operation by early June 2011. [2]

<span class="mw-page-title-main">Nuclear power in Japan</span> Overview of nuclear power in Japan

Prior to the 2011 Tōhoku earthquake and tsunami, Japan had generated 30% of its electrical power from nuclear reactors and planned to increase that share to 40%. Nuclear power energy was a national strategic priority in Japan. As of March 2020, of the 54 nuclear reactors in Japan, there were 42 operable reactors but only 9 reactors in 5 power plants were actually operating. A total of 24 reactors are scheduled for decommissioning or are in the process of being decommissioned. Others are in the process of being reactivated, or are undergoing modifications aimed to improve resiliency against natural disasters; Japan's 2030 energy goals posit that at least 33 will be reactivated by a later date.

The Fukushima Daiichi Nuclear Power Plant is a disabled nuclear power plant located on a 3.5-square-kilometre (860-acre) site in the towns of Ōkuma and Futaba in Fukushima Prefecture, Japan. The plant suffered major damage from the magnitude 9.0 earthquake and tsunami that hit Japan on March 11, 2011. The chain of events caused radiation leaks and permanently damaged several of its American-designed reactors, making them impossible to restart. By political decision, the remaining reactors were not restarted.

The Tōkai Nuclear Power Plant was Japan's first commercial nuclear power plant. The first unit was built in the early 1960s to the British Magnox design, and generated power from 1966 until it was decommissioned in 1998. A second unit, built at the site in the 1970s, was the first in Japan to produce over 1000 MW of electricity. The site is located in Tokai in the Naka District in Ibaraki Prefecture, Japan and is operated by the Japan Atomic Power Company. The total site area amounts to 0.76 km2 with 0.33 km2, or 43% of it, being green area that the company is working to preserve.

The electric power industry in Japan covers the generation, transmission, distribution, and sale of electric energy in Japan. Japan consumed 995.26 TWh of electricity in 2014. Before the 2011 Fukushima Daiichi nuclear disaster, about one third of electricity in the country was generated by nuclear power. In the following years, most nuclear power plants have been on hold, being replaced mostly by coal and natural gas. Solar power is a growing source of electricity, and Japan has the third largest solar installed capacity with about 50 GW as of 2017.

The 2011 Tōhoku earthquake and tsunami occurred at 14:46 JST on 11 March. The magnitude 9.0–9.1 (Mw) undersea megathrust earthquake had an epicenter in the Pacific Ocean, 72 km (45 mi) east of the Oshika Peninsula of the Tōhoku region, and lasted approximately six minutes, causing a tsunami. It is sometimes known in Japan as the "Great East Japan Earthquake", among other names. The disaster is often referred to in both Japanese and English as simply 3.11.

<span class="mw-page-title-main">Fukushima nuclear disaster</span> 2011 nuclear disaster in Japan

The Fukushima nuclear disaster was a 2011 nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan. The proximate cause of the nuclear disaster was the 2011 Tōhoku earthquake and tsunami natural disaster that occurred on 11 March 2011 and was the most powerful earthquake ever recorded in Japan. The earthquake triggered a powerful tsunami, with 13–14 meter high waves causing damage to the nuclear power plant. The result is the most severe nuclear accident since the Chernobyl disaster in 1986, classified as level seven on the International Nuclear Event Scale (INES), after initially being classified as level five, joining Chernobyl as the only other accident to receive such classification. While the 1957 explosion at the Mayak facility was the second worst by radioactivity released, the INES ranks incidents by impact on population, so Chernobyl and Fukushima rank higher than the 10,000 evacuated from the classified restricted Mayak site in rural southern Urals.

<span class="mw-page-title-main">Aftermath of the 2011 Tōhoku earthquake and tsunami</span> Subsequent events that took place after the 2011 Tohoku earthquake and tsunami

The aftermath of the 2011 Tōhoku earthquake and tsunami included both a humanitarian crisis and massive economic impacts. The tsunami created over 300,000 refugees in the Tōhoku region of Japan, and resulted in shortages of food, water, shelter, medicine and fuel for survivors. 15,900 deaths have been confirmed. In response to the crisis, the Japanese government mobilized the Self-Defence Forces, while many countries sent search and rescue teams to help search for survivors. Aid organizations both in Japan and worldwide also responded, with the Japanese Red Cross reporting $1 billion in donations. The economic impact included both immediate problems, with industrial production suspended in many factories, and the longer term issue of the cost of rebuilding which has been estimated at ¥10 trillion.

<span class="mw-page-title-main">April 2011 Miyagi earthquake</span>

The April 2011 Miyagi earthquake occurred off the coast of Miyagi Prefecture, approximately 66 kilometres (41 mi) east of Sendai, Japan. The Mw7.1 thrust earthquake was classified as an aftershock of the March 11 Tōhoku earthquake, and occurred at 23:32 JST (14:32 UTC) on Thursday, 7 April 2011.

A potent magnitude 6.6 Mw intraplate aftershock occurred at 17:16 JST (08:16 UTC) on 11 April, in the Hamadōri region of Fukushima, Japan. With a shallow focus of 13 km (8.1 mi), the earthquake was centred inland about 36 km (22 mi) west of Iwaki, causing widespread strong to locally severe shaking. It was one of many aftershocks to follow the 11 March Tōhoku earthquake, and the strongest to have its epicentre located inland.

Yanosuke Hirai Japanese civil engineer

Yanosuke Hirai was a Japanese civil engineer and corporate executive in the electric power industry. He developed electric power generation in the Tohoku region during the Shōwa era with unusual foresight and a deep sense of responsibility. 25 years after his death, Hirai’s foresight protected lives and environment from the March 11, 2011 Tohoku earthquake and tsunami. The Onagawa Nuclear Power Plant, designed and built under his watch, was the sole plant in the region that fully resisted the disaster of March 11, 2011: all of its three reactors successfully withstood the seismic event and subsequent tsunami, shutting down safely as designed and virtually without any incident. The site of the plant even ended up providing a refuge for three months to more than 300 neighboring people who had lost their homes.
