Nothing has really changed after the nuclear accident on March 11, 2011.
2 to 3 months after the March 11, 2011 disaster, just when the extent of radiation contamination became known - sewer sludge, ashes from garbage incineration exceeding 8,000 becquerels/kg - some people and organizations started the events of "beyond-nuclear" demonstrations, with celebrities and activists on stage telling the audience how they oppose nuclear energy.
It was not really about Fukushima or the residents of Fukushima, not really about radiation contamination and what to do with it; it was this beautiful concept of life without nuclear power. Then-LDP Secretary General and current Minister of the Environment and son of Shintaro Ishihara called "beyond-nuclear" movement a "mass hysteria" in June 2011.
I didn't think much of the moniker, "beyond-nuclear" or datsu genpatsu 脱原発, from the beginning.
About a year later, starting in March 2012, a group started the protest in front of the prime minister's office to oppose the restart of nuclear power plants. It's a "single issue" movement, the organizers said. The Friday protests were extensively covered by independent journalist Yasumi Iwakami. The movement fizzled after the organizers met with then-Prime Minister Yoshihiko Noda, and disdainful remarks from the organizers for the protest participants drew criticisms.
Meanwhile, food contaminated with radioactive cesium continued to be sold throughout Japan, so-called "hot spots" in Kanto and Tohoku regions remained mostly untouched, people continue to live in the contaminated middle-third of Fukushima Prefecture for one reason or another (job, children don't want to leave, etc.), and people are returning to the more contaminated ocean-third of Fukushima as the government promises them extra compensation money if they return. There has been a curious lack of coverage even by the independent journalists of contaminated food and wide-area disposal of disaster debris.
Two years later on March 10, 2013, people are still doing the same "beyond-nuclear" protest.
Here's from Hibiya Park in Tokyo, as tweeted by @noiehoie:
It's certainly a lot of people. It is as if I were back in September 2011.
I did like those local protests against particular politicians, though. The one against Yukio Edano in Saitama stood out.
