maybe i am touching a touchy topic but i have never had issues with yakuza. the funny thing is, a lot of yakuza in my experience tend to be very gaijin friendly while some aren't. most of my connections is through the fight world. i have been to underground fights disguised as mma events and a lot of the competitors and those in attendance were yakuza members. the funny thing is, they were very friendly to me and tried to speak to me in english. a few years ago, one guy dropped his sunglasses at the lobby of the arena and i picked it up for him in a crowded area and thought i was like the nicest guy in the world just for doing that. he went out of his way to buy me a drink. he introduced me to his gang and we just hit it off. Then he introduced me to his people. apparently this was a guy with influence and they opened me with open arms. they just asked me about my country, what i thought of japan, etc. his boss who was totally japanese og loved the fact i was into the 70s and 80s scene of japan and how much i knew about it. he told me i could have been like a king in roppongi in the 80s lol. i still talk to that guy and i know if i have any major problems, i can go to him. the police i know are good people here but they were more likely to give me shit more than yakuza over being a resident alien.
