"long live the emporer!"

Did some errands in Shibuya and found myself in the middle of a massive rightist's demo. The trucks were blaring traditional music, the flags were flying high, and for some reason the all assembled in front of the Citizen's Center, faced down a row of cops, and shouted "Kick out the North Koreans!"
In the window of the Citizen's Center was a banner announcing IT Retraining classes and after-school student playgroups for working parents' children.
The best part was all the folks like me; hanging out watching the show. Families with children stood stoicly between a line of police and a line of buzz-cut rightists, waiting for the light to change. When it turned green, an officer waved the people forward, waved the rightist truck over, and everyone crossed the street. When the light turned red and the sidewalk was clear, a skinhead (some kind of leader, giving orders all over the place) rushed the cops and was promptly pushed back and held down until he mellowed out.
Two girls on a shopping trip stopped to take a photo: one turned her back to the scuffle, faced her friend, and made a 'V' sign with her fingers while her friend took a photo of her, cops pinning down a couple of over-acting rightists in the background.
Another couple was taking photos when a young rightist jumped out of the truck and started yelling at him "What are you doing?! Taking photos?!" His girlfriend stepped between them, pushed him back with both hands, he brushed her off and continued shouting as they both walked away.
Totally surreal, as only can be experienced in Japan.
