This week's outage was a reminder that the plant remains vulnerable despite the government's claim that the reactors are in a "cold shutdown" state and no longer releasing high levels of radiation. The plant was brought under control in December 2011 and Monday's crisis was the first time since then that so many facilities had been affected by electrical failure at the same time.
The system cooling water which contained spent nuclear fuel rods failed and it took engineers more than a day to repair the damage.
Correspondents say the incident has highlighted the fragility of the rescue operation at Fukushima two years after the meltdowns caused a major release of radiation.
The Japanese government insists that the reactors are in a "cold shutdown" state and no longer releasing high levels of radiation.
But decommissioning the reactors is expected to take decades.
