On May 5, the Tomari nuclear plant in Hokkaido shut down for routine maintenance, leaving Japan with no operating nuclear-power plants. There is a confused debate over what to do next.

Prime Minister Yoshihiko Noda has called for restarting the reactors at Ohi plant in Fukui, insisting that bringing them online is imperative for the economy. Although the government may prevail, many Japanese remain skeptical about nuclear safety.

The public, and the local politicians who control the decisions to restart, are demanding that the government guarantee the safety of each plant. The government says new safety standards and a revamped regulatory regime will address these concerns.

In addition, a new commission that centralizes all the regulations for nuclear-power plants will be created.
