Time Out says
Japanese anti-nuclear demos aren't unusual, but they've never been very well attended. Until now, that is. A protest march in Ginza on March 27, campaigning against nuclear power, saw around 1,200 people turn out to express their displeasure - hardly the vast swathes you'd expect in other world capitals, but around 40 times more than the monthly gathering usually attracts (a hardcore gang of 30). Similarly, a March 20 protest in Shibuya attracted 1,000 disgruntled protesters.
The biggest yet, or so the organisers hope, will be the Hangenbatsu Choukyodai Demo (literally, the 'Anti-Nuclear Power Plants Super Huge Demo'), taking place in Koenji Chuo Park on April 10, organized by Shirouto no Ran. The event looks like being part protest, part rock concert, part charity event. The line-up features DJs Axeman and Yahman, MCs Rankin Taxi and Rumi, and live bands including Jintara-Mvta, a raucous big band that includes members of Cicala-Mvta, Soul Flower Union and others.
The gathering starts at 2pm, and the concert/demo will run between 3pm and 5pm, at which point the audience is encouraged to move to the Koenji Kitaguchi Hiroba area to donate money. The cash will go partly towards supporting the people of Koenji's sister city Minami Souma, a town located within the 30km Fukushima evacuation zone, and partly to the Sendai Birdland, a charity collective made up of musicians who are actively involved in getting supplies to Tohoku.

As you can see from the map below, the protest march (starting at 3pm) will start just south of Koenji Station (Chuo line), before winding its way around the streets of Koenji. A larger version of the map can be found here.
