Six years after a tsunami crashed into the Fukushima-Daiichi nuclear power plant, causing three of the plant’s seven reactors to melt down in the worst nuclear accident since Chernobyl, a Japanese district court in Fukushima prefecture ruled this week that Tokyo Electric Power and the Japanese government were liable for damages totaling about 500 million yen ($4.44 million) in the largest class action lawsuit brought over the 2011 nuclear disaster, Reuters reported citing local media sources.
