Summary
The Fukushima Daiichi nuclear power plant accident began on March 11, 2011, in Ōkuma, Fukushima, Japan, following the Tōhoku earthquake and tsunami. This natural disaster caused a widespread electrical grid failure and damaged backup power systems, preventing adequate cooling of the reactors. The subsequent loss of containment led to the release of radioactive contaminants into the environment, marking it as the most severe nuclear incident since Chernobyl. While the United Nations Scientific Committee on the Effects of Atomic Radiation reports no documented adverse health effects directly attributable to radiation exposure among Fukushima residents, there have been reports of cancer and leukemia in a few individuals, and two workers were hospitalized for radiation burns. Experts attribute increased detection rates of certain conditions in large-scale screening programs to enhanced medical surveillance rather than radiation exposure. The accident caused the displacement of at least 164,000 residents, leading to stress, fear, and at least 51 deaths, with over 41,000 people still living as evacuees a decade later. Investigations revealed failures in safety, risk assessment, and evacuation planning, and the disposal of treated wastewater remains a controversial issue. The estimated cost for cleanup and compensation reached 20 trillion yen (180 billion US dollars) by November 2016. The Fukushima nuclear meltdown was investigated by Kiyoshi Kurokawa, who, like other independent investigators of historical catastrophes, sought the truth despite institutional and technical failures.

On 11 March 2011, a major nuclear accident started at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan. The direct cause was the Tōhoku earthquake and tsunami, which resulted in electrical grid failure and damaged nearly all of the power plant's backup energy sources. The subsequent inability to sufficiently cool reactors after shutdown compromised containment and resulted in the release of radioactive contaminants into the surrounding environment. It is regarded by the United Nations Scientific Committee on the Effects of Atomic Radiation as the worst nuclear incident since the Chernobyl disaster. According to the United Nations Scientific Committee on the Effects of Atomic Radiation, "no adverse health effects among Fukushima residents have been documented that are directly attributable to radiation exposure from the Fukushima Daiichi nuclear plant accident". Insurance compensation was paid for one death from lung cancer, but this does not prove a causal relationship between radiation and the cancer. Six other people have been reported as having developed cancer or leukemia. Two workers were hospitalized because of radiation burns, and several other people sustained physical injuries as a consequence of the accident. Large‑scale screening programs, including thyroid examinations for children and ongoing epidemiological surveys, have reported elevated detection rates of certain conditions; however, experts attribute much of this increase to enhanced medical surveillance rather than radiation exposure itself. Following the accident, at least 164,000 residents of the surrounding area were permanently or temporarily displaced (either voluntarily or by evacuation order). The displacements resulted in at least 51 deaths as well as stress and fear of radiological hazards. The evacuation was accused of causing more harm than it prevented. Ten years later, over 41,000 people from Fukushima were still living as evacuees. Investigations faulted lapses in safety and oversight, namely failures in risk assessment and evacuation planning. Controversy surrounds the disposal of treated wastewater once used to cool the reactor, resulting in numerous protests in neighboring countries. The expense of cleaning up the radioactive contamination and compensation for the victims of the Fukushima nuclear accident was estimated by Japan's trade ministry in November 2016 to be 20 trillion yen (equivalent to 180 billion US dollars).

Fukushima (福島市, Fukushima-shi; ( "Help:IPA/Japanese")) is the capital city of Fukushima Prefecture, Japan. It is located in the northern part of the Nakadōri or central region of the prefecture.

[...] Fukushima has the third-highest population in the prefecture, behind the cities of Iwaki, with 377,288, and Kōriyama, with 336,328. This makes Fukushima the only prefectural capital in Japan that is the third-largest city in the prefecture. The Fukushima metropolitan area had a May 2011 estimated population of 452,912 and consisted of the towns and cities of Nihonmatsu, Date, Kunimi, Koori, Kawamata, and Fukushima. It is the second most populous metropolitan area in Fukushima Prefecture, with the Kōriyama metropolitan area being the largest with a population of 553,996. The Fukushima metropolitan area is also the sixth-largest metropolitan area in the Tōhoku region. [...] On April 1, 1907, the town of Fukushima officially became the city of Fukushima (福島市, Fukushima-shi). It was the second municipality in the prefecture and 59th in the nation to become a city. At the time, Fukushima had a population of 30,000. On April 14, 1908, the Shintatsu Tramway Company (信達軌道会社) opened a light rail system that connected Fukushima Rail Stop (福島停車場) to Yuno (湯野) via Nagaoka (長岡). Also in 1908, the Fukushima City Library (福島市立図書館) opened. On June 28, 1918, the Fukushima Race Course held its first horse race. On August 30 of the same year, rice riots occurred in the city.

Fukushima Prefecture (福島県, Fukushima-ken; pronounced ( "Help:IPA/Japanese")) is a prefecture of Japan located in the Tōhoku region of Honshu. Fukushima Prefecture has a population of 1,771,100 (as of 1 July 2023( and has a geographic area of 13,783.90 square kilometres (5,321.99 sq mi). Fukushima Prefecture borders Miyagi Prefecture and Yamagata Prefecture to the north, Niigata Prefecture to the west, Gunma Prefecture to the southwest, and Tochigi Prefecture and Ibaraki Prefecture to the south. [...] Fukushima city is located in the Fukushima Basin's southwest area and nearby mountains. Located on the central eastern seaboard a part of the Pacifim rim.

# Fukushima Britannica AI Icon Fukushima, ken (prefecture), northeastern Honshu, Japan, facing the Pacific Ocean. It is mostly mountainous, and settlement is concentrated in small interior basins and along the coast. Inawashiro Lake, 40 square miles (100 square km) in area, occupies the centre of the prefecture. The southeastern portion of Bandai-Asahi National Park is in the northwestern corner of the prefecture, the park encompassing the region of the volcanic Bandai and Azuma mountains. The lower volcano slopes are dotted with lakes and swamps, many of which were formed by the eruption of Mount Bandai in 1888. Numerous spas serve the area. [...] Fukushima prefecture is essentially agricultural, producing rice surpluses and such cash crops as tobacco, mulberry (silk), fruits, grains, and vegetables that are resistant to low temperatures. Forestry and fishing and the gathering of seaweed in coastal cities such as Iwaki in the southeast are also important. Coal mining was important at the Jōban coalfield (now part of Iwaki) southeast of Kōriyama until production was discontinued in the late 20th century. Industry is concentrated in a few cities such as Fukushima (the prefectural capital), Iwaki, and Kōriyama; cameras, silk and rayon yarn, silk textiles, fruits, bonsai trees, and kokeshi dolls are produced. [...] On March 11, 2011, the prefecture was struck by a severe earthquake (magnitude 9.0) centred offshore to the northeast in the Pacific. Although the temblor and a series of aftershocks caused some damage, considerably more destruction was done by a powerful series of tsunami waves, generated by the main shock, that inundated coastal areas. Particularly hard-hit were Iwaki and the Fukushima Daiichi (“Number One”) nuclear power station located along the prefecture’s northeast coast. The degree of property damage in the affected areas was considerable, including more than 85,000 buildings either wholly or partially destroyed, and about 1,800 people were killed by the tsunami or were missing and presumed dead. However, in the weeks and months following the disaster, another major crisis
