On Wednesday night Japan restarted the No.4 reactor at the Oi nuclear power plant in Fukui Prefecture. It is the second reactor to restart after being closed down for safety checks.

The reactor is expected to begin generating electricity on Saturday and reach full operation next Wednesday. When it reaches its full capacity, the government will remove power-saving restrictions for Chubu, Hokuriku, and Chugoku. Restarting the two reactors is an attempt to head off a serious power shortage this summer. 48 reactors remain shut down since the No.1 Fukushima nuclear power plant crisis.
