On August 24, 2022, Japanese Prime Minister Fumio Kishida said the country will restart more idled nuclear power plants and consider developing safer, smaller nuclear reactors, signaling a renewed emphasis on nuclear energy a decade after the Fukushima disaster.[1] PM Kishida also said the government would look at extending the lifespan of existing reactors. The prime minister made the announcement at a "green transformation" conference focused on the country’s efforts to meet its environmental goals. The statement represents a policy shift; previously, the Japanese government has said it was not considering building new plants or replacing aging reactors.

Following the Fukushima nuclear plant disaster in 2011, most of Japan's nuclear power plants were taken offline for safety checks under tightened standards. Since then, utilities have set more than 20 reactors for decommissioning. Of the 33 reactors, 25 have been screened for safety checks by the Nuclear Safety Authority (NRA). Seventeen have been approved, but only ten have restarted. Japan’s government has previously announced plans to speed up restarts. It aims to have up to nine reactors restarted by winter 2022 to cope with energy constraints and to restart seven other reactors after summer 2023. The government also aims to extend the life of aging reactors to beyond 60 years from the initial 40 years.
