1 person was an exaggeration. A small group of people actually partake in that stuff, and decent normal people happen to stand by while doing it. That's my theory at least. The way I see it, it's possible it could be that, it could be that Japan is the only country with a sense of humor (lol), or maybe all those weird happenings are only in a single city in Japan.
Yo Daenth, did you see any weird stuff in Japan?
