TOKYO (AP) — Nobel laureate Kenzaburo Oe urged Japan’s new prime minister on Tuesday to halt plans to restart nuclear power plants and instead abandon nuclear energy.

Oe cautioned Prime Minister Yoshihiko Noda against prioritizing the economy over safety. Noda has said he will allow idled nuclear plants to resume operation when their safety is confirmed.

“The new prime minister seems to think that nuclear power plants are necessary for Japan’s economy, and how to resume their operation is one of his key political agendas,” Oe said. “We must make a big decision to abolish all nuclear plants.”

Oe, who won the Nobel Prize in literature in 1994, said the accident at the Fukushima Dai-ichi power plant six months ago caused the Japanese public to want to reduce their dependence on nuclear power, but that feeling seems to be fading.

He spoke at news conference yesterday about an anti-nuclear petition drive, accompanied by other members of the campaign.

The group, which is demanding that the government decommission aging reactors and promote renewable energy, aims to collect 10 million signatures and submit them to the government next March.

Oe has actively supported pacifist and anti-nuclear campaigns and written books about the U.S. atomic bombings of Hiroshima and Nagasaki at the end of World War II.
