Fukushima 50 is a 2020 Japanese disaster drama film directed by Setsurō Wakamatsu and written by Yōichi Maekawa. Starring Koichi Sato and Ken Watanabe, it is about the titular group of employees tasked with handling the meltdown of the Fukushima Daiichi Nuclear Power Plant after the 2011 Tōhoku earthquake and tsunami. The film is based on the book by Ryusho Kadota, titled On the Brink: The Inside Story of Fukushima Daiichi, and it is the first Japanese film to depict the disaster.

Synopsis
At 2:46 p.m. on 11 March 2011, the largest earthquake in Japan's recorded history with a magnitude of 9.1 and a maximum seismic intensity of 7 occurred. A huge tsunami struck the Fukushima Daiichi Nuclear Power Plant. It was clear that a nuclear reactor lost all power due to flooding by the tsunami. A station blackout (SBO) caused the reactor to fall into an uncoolable situation and suffer unimaginable damage due to nuclear meltdown.

On-site workers, including Izaki Haruka, who is on duty at Units 1 and 2, remain in the nuclear power plant and work hard to control the reactor. Director Masao Yoshida, who oversees the overall command, inspires his subordinates, but also expresses anger at the head office and the Kantei (Prime Minister's Office), which are not fully aware of the situation. However, the efforts at the site were in vain and the situation continued to worsen, forcing the surrounding people to evacuate.

In the worst scenario of this accident estimated by the Kantei, the damage range would have a 250 km radius with the evacuation target population of circa 50 million people, which meant the destruction of eastern Honshu (largest main island). The only option left on the scene is "venting", which has never been done before in the world and requires manual labor by a worker to rush into the reactor with their body. The operation finally began while it was cut off from the outside world and no information entered.

Reception
Mark Schilling of The Japan Times gave the film a positive review, stating it "strives, boldly for a mainstream film, to tell certain home truths, from the profits-first mindset of the plant's operators."
The storyline suggesting that the Prime Minister of Japan directly boarded the nuclear power plant and delayed the venting process, leading to an expansion of the damage, is contradicted by the report of the accident investigation committee, which has completely refuted this claim. The delay in venting was primarily due to manual preparations taking time, unrelated to the Prime Minister's inspection.Science journalist Takafumi Soeda criticizes the movie for portraying the Fukushima accident as an unforeseen event caused by a tsunami beyond human expectations, while in reality, TEPCO executives, led by Director Yoshida, decided to delay tsunami countermeasures until 2016, despite technical experts at TEPCO already concluding in 2008 that tsunami countermeasures were inevitable. The accident could have been avoided if TEPCO had taken tsunami countermeasures to the same extent as other power companies. Soeda argues that the movie overlooks TEPCO's responsibility and obscures the true nature of the accident by presenting it as a heroic tale from the site. Furthermore, the author of the movie's source material, Ryusho Kadota, is a central figure in promoting far-right conspiracy theories in Japan, including QAnon conspiracy theories.
