Japan's top court on Friday dismissed claims that the government should pay damages in cases involving around 3,700 people whose lives were seriously affected by the 2011 Fukushima nuclear disaster, absolving the state of responsibility for mass evacuations in the crisis.

The decision by the Supreme Court's Second Petty Bench was the first for the top court and covered four lawsuits filed in Fukushima, Gunma, Chiba and Ehime prefectures. Around 30 such lawsuits have been filed across Japan by people who had to evacuate from their home or whose lives were greatly impacted by the earthquake— and tsunami-triggered disaster.

The ruling leaves Tokyo Electric Power Company Holdings, the operator of the crippled Fukushima No. 1 nuclear power plant, solely responsible for slightly over ¥1.4 billion ($10.5 million) in damages in the four lawsuits. The top court finalized the utility's liability in March for the first time.
