The Fukushima Daiichi nuclear disaster (福島第一原子力発電所事故 Fukushima Daiichi was a nuclear disaster at the Fukushima I Nuclear Power Plant on 11 March 2011, resulting in a meltdown of three of the plant's six nuclear reactors. The failure occurred when the plant was hit by a tsunami triggered by the magnitude 9.0 Tōhoku earthquake. The plant began releasing substantial amounts of radioactive material on 12 March, becoming the largest nuclear incident since the Chernobyl disaster in April 1986 and the second (after Chernobyl) to measure Level 7 on the International Nuclear Event Scale, initially releasing an estimated 10-30% of the earlier incident's radiation. In August 2013, it was stated that the massive amount of radioactive water is among the most pressing problems affecting the cleanup process, which is expected to take decades. There have been continued spills of contaminated water at the plant, and some into the sea. Plant workers are trying to lower the leaks using measures such as building chemical underground walls, but they have not yet improved the situation significantly.

Although no short term radiation exposure fatalities were reported, some 300,000 people evacuated the area, 15,884 (as of 10 February 2014) people died due to the earthquake and tsunami, and as of August 2013 approximately 1,600 deaths were related to the evacuation conditions, such as living in temporary housing and hospital closures. The exact cause of the majority of these evacuation-related deaths were unspecified because that would hinder the deceased relatives' application for financial compensation. The World Health Organization indicated that evacuees were exposed to so little radiation that radiation-induced health impacts are likely to be below detectable levels, and that any additional cancer risk from radiation was small—extremely small, for the most part—and chiefly limited to those living closest to the nuclear power plant. A 2013 WHO report predicts that for populations that would have stayed and lived in the most affected areas, and according to the (disputed) LNT hypothesis, there would have been a 70% higher risk of developing thyroid cancer for girls exposed as infants (but experts said the overall risk was small:
