Organisers estimate that 170,000 people took part in a demonstration in Tokyo today (Mon) against the government's decision to turn on nuclear reactors at the Ōi Nuclear Power Station in the Fukui prefecture.
Last week unit three at the power station became Japan's first reactor to resume full operation since the nuclear disaster last year.
Despite the government's tests and safety claims, antinuclear sentiment remains. Many claim that the meltdown at the Fukushima Plant was the worst nuclear disaster since Chernobyl.
Following the initial announcement that the reactors would be turned on thousands of people took to the streets including a group of protesters blocking entrances to the plant. The government went ahead with the plans, and are now looking to reactivate unit 4.
Yasunari Fujimoto, an organizer of the rally has said:
"We want to continue to stage demonstrations as antinuclear sentiment is growing among the people."
