Did the Yakuza ever get involved in the heroin trade? I never heard much about heroin being a thing in Japan, they got some strict drug laws. I know Japan isn't that close to the Golden Triangle, but where there is money to be made... I like to read and watch stuff about the Golden Triangle, but a lot of the resources are too political for my taste. I'm interested in the actual trade, the players involved, the violence that comes with it, etc. I don't want to hear some talking suit from the U.N..
