Japan(Yakuza)

Anyone who says that they are cool or that they tend not to bother foreigners doesn't really know them. They suck as humans. They prey on the weak. Schoolgirls and divorcees are often forced into porn by these guys - ever watch Japanese porn? - if so, you've likely seen a yakuza victim.

They do occasionally rub elbows with foreigners, but the average foreigner (and many Japanese) are too oblivious or not culturally aware enough to realize it. They are still very involved with the entertainment industry - more than the average foreigner realizes. The idea of all yakuza having bodyguards around them is laughable, the lower level guys are the bodyguards, and they are often out without their bosses. You've seen them, if you live here, but just didn't realize it
