For example, the impact of the ruling will be closely monitored, the media said.
The plaintiffs sought damages from both Tepco and the country in several class-action lawsuits, and in March the Supreme Court upheld Tepco’s order to pay 1.4 billion yen in damages to nearly 3,700 people.
Japanese Chief Cabinet Secretary Hirokazu Matsuno declined direct comment when asked about the ruling at a news conference, although he said he was aware of it.
“Despite the decision, we will remain close to those affected by the disaster and will continue to do our best to rebuild and revive Fukushima,” he said.
About 470,000 people were forced to evacuate in the first days after the disaster, and thousands still have not been able to return.
Lower courts were divided over the extent of the government’s responsibility in predicting the disaster and ordering Tepco to take steps to prevent it.
