Japan prepares to restart world's biggest nuclear plant, 15 years after Fukushima

The Japanese region of Niigata is expected to endorse a decision to restart the world's largest nuclear power plant on Monday, a watershed moment in the country's pivot back to nuclear since the 2011 Fukushima disaster.

Kashiwazaki-Kariwa, located about 220 km (136 miles) northwest of Tokyo, was among 54 reactors shut after a massive earthquake and tsunami crippled the Fukushima Daiichi plant in the worst nuclear disaster since Chernobyl.
