[1] Both units were put in a temporary shutdown in the wake of the 2011 Fukushima Daiichi nuclear disaster and received safety upgrades to comply with stricter regulatory requirements.

The utility put in a request to the Ishikawa prefectural government and the town of Shika for the restart of unit 1.

Following the 2011 Fukushima nuclear accident, the plant was temporarily shut down in March 2011 to make changes in order to comply with new regulatory requirements.

[13] After finishing the safety upgrades, permission for the restart of unit 2 from the Nuclear Regulation Authority (NRA) was first sought in August 2014.

[12][15] Earlier, the NRA had reached a unanimous decision not to seek further opinion from experts who raised concerns of the faults being active.

[16] In January 2024 the plant was closest to a magnitude 7.6 earthquake in Ishikawa Prefecture, and survived the event with no major damage.

[22] On 17 April, NHK reported that a section of the No.1 reactor control system had been dislodged by the quake, and that the Nuclear Regulation Authority chairperson instructed the operator for constructural improvements.

[23] Evacuation plans have since been questioned, with the majority of the Ishikawa prefecture designated routes for resident to flee the 30-km radius were cut off, leaving communities isolated.

[24] On 13 May 2024, Kanazawa District Court held a hearing on a case, in which the plaintiffs are seeking the plant's decommission.
