Japan revives giant nuclear plant

After fifteen years of silence, the Kashiwazaki-Kariwa plant, the world’s biggest nuclear facility, has powered up one of its reactors. The move marks Japan’s bold step to restore nuclear capacity after the 2011 disaster.

Officials say the restart follows stringent safety checks and new regulations. Yet the shadow of Fukushima still haunts public debate, with many watching closely to see if confidence can be rebuilt in the coming years.

For households and businesses, the revived reactor could stabilise electricity prices and reduce reliance on imported fuels, while also influencing Japan’s climate targets and energy security outlook in the coming years.

The restart signals Japan’s willingness to lean on nuclear power to meet decarbonisation goals, but it also revives safety concerns, potentially shaping regional energy policies and public trust in nuclear technology.
