Japan eyes restart of the world’s largest nuclear plant 15 years after Fukushima

As Japan marks 15 years since the Fukushima disaster, Tepco plans to restart reactor No. 6 at Kashiwazaki-Kariwa, the world’s largest nuclear plant in Niigata. The move, aimed at boosting energy security and emissions targets, faces fierce local opposition and safety concerns about evacuation capabilities for hundreds of thousands nearby. A delay due to a test alarm was followed by expectation it will go online soon, potentially adding about 2% to Tokyo-area electricity, but critics say safety and trust remain doubtful.
