It was enough to give me chills. Today I was walking around in the subway when I heard this incredible shouting coming in every exit. I ran up to the top to see what was going on, and there in the biggest round-a-bout in Nagoya sat about eight massive trucks, painted black or brown, with massive loudspeakers on top. They were blaring with such volume that everyone around was covering their ears, and the echo rang through the streets, even ten minutes after they had driven off. Apparently, these are the campaign tactics of Japan's extreme right wing, the Uyoku. It was a little unnerving how busy Nagoya station just kinda ground to a halt and watched. Made me wonder what Hitler's rallies and military displays must have been like.
Anyway, if you're curious, I found some info here. There are blurbs about other fringe groups in Japan as well.
