I lived in Osaka Japan for a year. The Japanese mafia is pretty big there - something out of the movies really.

I remember staring at people with stumps instead of fingers and thinking "ohh you Pooor thing - frostbite" then I was told later that the thing was to cut your own finger off if you needed to say sorry to the mafia!

They all drive black cars too apparently. The owner of the boxing gym I lived in over there drove a black car but I don't think he was mafia ..... at least as far as I know!

I felt pretty safe there though - just because I'm small by Australian standards - but not Japanese - and many Japanese are apparently a little afraid of western women because we're so much noisier than Japanese women.
