FUKUI, JAPAN — A Japanese court on Thursday cleared the way for Kansai Electric Power Co. to restart four nuclear reactors, rejecting legal claims against Japan's second-biggest utility to keep the reactors idled over safety concerns. The Fukui District Court overturned an injunction that has prevented the restart of two reactors at Kansai's Takahama power station, and rejected a request for an injunction to block the restart of two reactors at its Ohi plant, plaintiffs' lawyers said. The decision paves the way to restart the units in western Japan nearly five years after the Fukushima crisis.
