Fukushima residents have told Japanese government officials at a public hearing on energy policy to get out of nuclear power and do it fast.
The Fukushima hearing, the ninth out of 11 planned nationwide, sought to gather views on nuclear power's role in the nation's energy mix as the government struggles to cover a power shortfall that could threaten economic growth.
Meltdowns at Tokyo Electric Power Co.'s Fukushima nuclear plant after an earthquake and tsunami on 11 March last year caused radiation to spew over large areas of Fukushima, forcing more than 160,000 people to flee. In the following months, all of Japan's nuclear plants were shut for safety checks. Two reactors resumed operations last month.
"I want all the reactors in Japan shut immediately and scrapped," a grey-haired woman, who introduced herself as a farmer living 65km (40 miles) from the Fukushima plant, said at the public hearing in the prefecture capital.
"Many people are now aware that the government's talking of 'no immediate risk to health' is tantamount to 'long-term health risk'," she said to the applause of about 200 residents packed in a small concert hall.
Goshi Hosono, minister in charge of the response to the nuclear crisis, was heckled as he apologised for the suffering of people in Fukushima.
"I will never forget what I heard today, and I'm determined to do everything I can," he said.
On Wednesday, Fukushima prosecutors launched an investigation after more than 1,000 residents filed criminal complaints against 15 former and present Tokyo Electric Power officials, including former company president Masataka Shimizu, and 18 government officials, including Nuclear Safety Commission head Haruki Madarame, a lawyer for the group, Hiroyuki Kawai, said.
Kawai said Tokyo prosecutors had launched a separate investigation.
A panel of experts appointed by parliament last month concluded that the disaster could have been prevented and that failure to take precautions was the result of "collusion" among the utility, regulators and the government.
"After reading the report by the parliament-appointed panel, prosecutors could not stand idly by," Kawai said.
Japan met about a third of its energy needs with nuclear power before the disaster and had plans to boost that share to more than half, partly to combat global warming.
Three options that the government has put on the table are to phase out nuclear power as soon as possible, aim for a 15 per cent share of the power supply by 2030, or a 20-25 per cent share by the same date.
Residents of Fukushima, 240km (150 miles) north of Tokyo, overwhelmingly backed the zero option, with all but one of the 30 who were picked in a draw to speak backing a swift exit.
The Asahi newspaper reported this week that elsewhere 70 per cent of those taking part in the hearings opted for the nuclear-free scenario. It is not clear how the hearings will affect the final energy plan that could come as soon as this month.
But commentators said it would be hard for the government to ignore the findings as, 17 months after the world's worst nuclear accident since Chernobyl, many still live in fear and the thousands hired to dismantle the Fukushima plant face decades of gruelling and dangerous work.
Prime Minister Yoshihiko Noda's decision to restart two reactors in Japan's western manufacturing hub to avoid blackouts galvanized the anti-nuclear movement.
More than 100,000 people attended an anti-nuclear rally last month and protests staged weekly outside of Noda's residence have grown, with ordinary workers and mothers with children joining the crowds.
"I'm scared. I'm really scared," said a middle-aged woman, addressing the hearing.
"I'd like the government to think about why people have gathered in front of the Prime Minister's residence every Friday since April. That's not fashion. That's not a temporary fever. That's a heartfelt scream from the public."
