Over 5,000 people rallied in Tokyo’s Hibiya Park on Saturday to demand the government scrap a plan to restart commercial nuclear reactors in Japan.

The protest comes shortly after the three-year anniversary of Japan’s March 2011 earthquake and tsunami that led to the meltdown of fuel-rods at several reactors at the Fukushima nuclear plant, prompting the worst nuclear disaster the world has seen since Chernobyl. The plant continues to leak radiation, and neither owner TEPCO or the Japanese government have offered a clear plan for stabilization.

“We have to seriously think about whether nuclear power is a good idea for Japan,” said protester Masatoshi Harada, quoted by AFP. “This is an opportunity for Japan to drop nuclear power.”

In addition to Saturday’s march, Fukushima cleanup workers demonstrated at the headquarters of TEPCO on Friday to protest dangerous working conditions and poor wages, Al Jazeera and AFP report. A similar worker protest took place Friday outside Maeda Corp, one of the contractors hired to cleanup the ravaged plant.
