TOKYO — Tens of thousands of people rallied at a Tokyo park Monday demanding that Japan abandon nuclear power as the country prepares to restart another reactor shut down after last year’s tsunami caused meltdowns at the Fukushima power plant.

Led by Nobel-winning novelist Kenzaburo Oe, pop star Ryuichi Sakamoto and visual artist Yoshitomo Nara, the protesters expressed outrage over a report that blamed the Fukushima disaster on Japan’s culture of “reflexive obedience” and held no individuals responsible.

Japan ordered all its nuclear power plants shut down for safety inspections after last year’s March tsunami and earthquake set off multiple meltdowns at Fukushima Dai-ichi plant. Some 150,000 people evacuated from a 12-mile zone around the plant because of radiation fears, and the area is deemed unsafe to live in more than a year later.

The world’s second-worst nuclear accident after Chernobyl has deeply divided Japan, which had been previously bullish on nuclear technology.
