As a consequence of the Great East Japan Earthquake and ensuing tsunami on March 11, 2011, the cores of the first to third nuclear reactors at the Fukushima Daiichi Nuclear Plant underwent meltdowns as external power for the cooling pumps was lost. As a result, a huge amount of radioactive particles was released into the air. These particles were carried by southeasterly winds to Iitate Village, Fukushima City, and Nakadori, a central region of Fukushima Prefecture, leaving high levels of radioactive contamination in their wake. The particles were further carried along multiple routes creating radioactively contaminated areas in regions from Ibaraki to Tokyo and Kanagawa Prefecture, as well as in Northern Kanto and the Tohoku Region (Northeastern Japan).
