While the Bloods & Crips are dangerous/ violent. They don''t have shyt on the Yakuza. The Yakuza is the MOST dangerous organize crime group in Japan. I know they run the porn, anime, combat sports, and used to be in the wrestling industry. I know Pro Wrestling NOAH & PRIDE FC (Defunct MMA Company) had a Yakuza scandal. That's what made PRIDE go under. Anyway, they know how to be organized and intimidating. They are very organized and have offices set up. These are guys you DON'T wanna fukk with. So, if you go to Japan don't get in their way. I know one directer he was Japanese made Yakuza movies. The Yakuza wasn't happy about it, so they had him killed While I don't glorify gang violence The Yakuza has always intrigued me. Pluys, I know they had operations in Hawaii too. Here's the two vids down below.
