Protests of any size are rare in Japan. But tens of thousands of demonstrators gathered in front of the prime minister’s residence on Friday, in the largest display yet of public anger at the government’s decision to restart a nuclear power plant, The New York Times reported. It was described as the largest protest in central Tokyo since the 1960s.   Local media estimated the crowd at between 20,000 and 45,000. But organizers estimated the number of participants to be more than 100,000.

The massive demonstration was called to protest a government decision to restart Sunday two reactors at the Oi plant in western Japan, Wall Street Journal said. It was the 14th demonstration organized by a coalition of anti-nuclear groups outside the premier’s residence since March 29.
