Japan's burgeoning anti-nuclear movement will be marking the three month anniversary of the March 11 quake and tsunami with a nationwide day of protests, amidst reports that Japan's nuclear reactors may all be shut down by next April. Organisers are touting the day as a '100-man-nin akushon' (1 million-strong action), and there are nearly a dozen marches happening in Tokyo alone - although whether that's evidence of widespread support, or of a movement that's still hopelessly fragmented, is debatable. The largest demos will centre on Shinjuku, Shibuya and the well-trodden route from Shiba Park to Tokyo Station.
Hashtag to follow related activity on Twitter: #611nonukes. Looks like the primary organizing site is nonukes.jp (partial English translation here). They are calling for supporters around the world to organize demonstrations in solidarity:
The day marks three months after the Fukushima nuclear disaster triggered by the earthquake and tsunami. The plants are still spewing radioactive materials. No one wants such dirty electricity harmful to human and nature. Join us on June 11th with million-people action throughout the world and let our voice heard. (...) Our solidarity, if you are in Japan, in Asia, in Europe, in Americas, or anywhere in this world, will soon end this dark age of nuclear power generation.
