What is 2011 Tōhoku
Earthquake and Tsunami?
The 2011 Tōhoku earthquake and tsunami was a catastrophic event that struck Japan on March 11th. A powerful 9.0 magnitude earthquake off the coast of northeastern Japan triggered a massive tsunami that devastated coastal communities, causing widespread destruction, loss of life (over 18,000), and displacement. The disaster also resulted in a nuclear accident at the Fukushima Daiichi Nuclear Power Plant, leading to the release of radioactive materials and long-term environmental and health concerns. The event had a profound impact on Japan, prompting a reevaluation of disaster preparedness and the role of nuclear power.
The Fukushima Daiichi
Nuclear Plant Accident
The 2011 tsunami caused a severe nuclear accident at the Fukushima Daiichi Nuclear Power Plant. Flooding disabled the cooling systems, leading to meltdowns in three reactors and the release of radioactive materials. The incident was classified as a Level 7 event, the highest on the International Nuclear Event Scale. Over 150,000 residents were evacuated due to radiation risks. The accident sparked global debates on nuclear safety and prompted many countries to reevaluate their energy policies. Decommissioning the plant and cleaning up the area remain ongoing challenges, expected to take decades. The Fukushima disaster highlighted the risks of nuclear power in disaster-prone regions.
Story
Were the images we saw reported by the media that day the whole truth?
Why were we so helpless in the face of nuclear disaster?
Now, the hidden stories are coming to light.
Japan teetered on the edge of disaster on March 11, 2011, as the Great East Japan Earthquake triggered a catastrophic meltdown at Fukushima Daiichi. Overheated reactors, deprived of cooling, threatened a Chernobyl-scale catastrophe. Amidst the chaos, scientists struggled to find solutions, the government grappled with misinformation, and citizens were forced to flee their homes. The relentless ticking of the clock marked the progression of a crisis that seemed insurmountable. A series of hydrogen explosions, beginning with Unit 1 on March 12, pushed Japan closer to the abyss.
One event, different realities...
“Abandoning Fukushima power plant is unacceptable. That would threaten the very existence of this country.”
– Prime Minister Kan
“No, no. Venting has never been tried anywhere else before.”
– Chief of The Nuclear Safety
Commission of Japan
“Doesn’t ordering them to stay mean forcing them to work at the risk of their lives?”
– Journalist Nabeshima
“We were the only ones who weren’t told about this… Will we be able to return home…?”
– Fukushima Residents

Reviews
Sets it apart from other films
This movie is different from other movies. It depicts the situation at the Prime Minister’s Office at the time, the confusion, and the information concealment by TEPCO. This movie is worth watching.
We all should watch this film before heading to the polls.
To ensure we never forget the major disaster that happened five years ago and to prevent it from happening again, I think it’s a good idea to watch this film before heading to the polls.
Powerful and enlightening film
This is a powerful and enlightening film that vividly captures the reality of how both the government and TEPCO misled the public by hiding the truth during a major nuclear crisis that shook the nation. A must-watch!!
Where can we go to live a normal life?
This country still carries the risk of potential destruction… ‘Where can we go to live a normal life?’ I want to quietly ask this question to the reactivated nuclear plants.
