Japan restarted the first nuclear reactor in more than three years, a long-awaited step forward for the nation’s utilities that are struggling to gain local support and fulfill onerous regulatory requirements.

Kansai Electric Power Co. on Wednesday morning resumed operations of its Mihama No. 3 reactor, which has been offline for more than a decade, according to a faxed statement. Still, the unit will likely have to temporarily shut down again later this year as it won’t be able to finish required upgrades ahead of an October deadline.
