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 meltdown at the Fukushima power plant.
The peaceful demonstration highlighted the growing opposition to atomic energy in the country.
"The plants leave too much behind. And so things that can't be properly and completely controlled by humans shouldn't be used," said rally participant.
Led by pop star, Ryuichi Sakamoto, protesters also expressed outrage over a report that blamed the Fukushima disaster on Japan's culture of "reflexive obedience" and held no individuals responsible.
Moreover, the movement's leaders say they have collected 7.4 million signatures for a petition demanding a phase-out of nuclear power.
Japaneese Prime Minister, Yoshohiko Noda said, some nuclear energy was needed to ensure an ample power supply and protect people's livelihoods.
Nevertheless, critics are not convinced, saying Japan has done fine without atomic energy for more than a year.
