Japan restarted the first reactor of its largest nuclear plant in Niigata after nearly 14 years idle, with the unit expected to displace 1.3 million metric tons of imported natural gas annually and produce 9,500 GWh per year. The restart faced regulatory and local consent challenges, with other nuclear units in Japan similarly delayed by safety upgrades and approval processes.

This Wire brief sits within Fusion42's coverage of Climate Tech.

◆ The Wire takeaway

You can target Japan’s energy market now that nuclear power has resumed displacing gas imports after long delays. This restart proves regulatory and local approval barriers can be overcome, opening demand for support services and upgrades.
