The 東日本大震災 (Great East Japan Earthquake) occurred on March 11, 2011. It was a powerful magnitude 9.0 earthquake off the coast of 宮城県 (Miyagi Prefecture) that triggered a massive tsunami. The disaster caused widespread destruction, particularly in the 東北地方 (Tohoku region), leading to significant loss of life and damage to infrastructure. The tsunami also caused a nuclear accident at the 福島第一原子力発電所 (Fukushima Daiichi Nuclear Power Plant), resulting in the release of radioactive materials. Recovery efforts have been ongoing, focusing on rebuilding communities and addressing the long-term effects of the disaster on the environment and public health.
