Each one tells a story of innovation, risk, and the human endeavor to harness one of the most potent forces known to science.

The Impact of the 2011 Earthquake and Tsunami

Guys, it's impossible to talk about Japan's nuclear reactor locations without addressing the massive impact of the 2011 Great East Japan Earthquake and Tsunami. This catastrophic event, centered off the coast of Tohoku, had devastating consequences, most notably at the Fukushima Daiichi Nuclear Power Plant. The earthquake itself caused significant shaking, but it was the subsequent tsunami, towering over 15 meters in some areas, that overwhelmed the plant's defenses. It crippled the cooling systems, leading to meltdowns in three of the reactors and the release of significant amounts of radioactive material into the environment. This disaster fundamentally altered Japan's relationship with nuclear power and its approach to managing these facilities.

Before 2011, nuclear power was a cornerstone of Japan's energy strategy, seen as essential for energy independence and reducing carbon emissions.
