Turnbull must definately know this

Main ones:

Japan - Yakuza, crazy ass guys with crazy tattoos all over the body. My father once when he visited Japan, he went for dinner with some friends to this very reasonable nice restaurant somewhere in Kobi, and as he walked outside he saw like a group of japanese guys all dressed in black suits walking out of a Hummer. See pic here.
Russia - Very ruthless
Italy - very family-central, romantic, passsionate and trustworthy.

I go for tha italy, Sicily.
