Demonstrators congregated at Hibiya Park, close to central government buildings, before marching around the national parliament.
They gathered to voice their anger at the nuclear industry and the government of Prime Minister Shinzo Abe, who has called for resumption of nuclear reactors to power the world’s third largest economy.
“I felt it’s important that we continue to raise our voice whenever possible,” said Yasuro Kawai, a 66-year-old businessman from Chiba prefecture, east of Tokyo.
“Today, there is no electricity flowing in Japan that is made at nuclear plants. If we continue this zero nuclear status and if we make efforts to promote renewable energy and invest in energy saving technology, I think it’s possible to live without nuclear,” Mr Kawai said.
This week, Japan will mark the anniversary of the deadly 9.0-magnitude earthquake that hit the northern region on March 11, 2011, that prompted a killer tsunami that swept the northern Pacific coastline.
The natural disasters killed 15,884 people and left 2636 people still unaccounted for. Huge waves swamped cooling systems of the Fukushima plant, which went through reactor meltdowns and explosions that spewed radioactive materials to the vast farm region.
