For the yakuza it doesn't matter were you came from, which country or from which class of society you belonged to, you can become a member anyway. Yakuza takes care of the misfits in the society. Yakuza members can be youth that been abandoned by their parents, youths seeking refuge from the high pressures of school, refugees from Korea, China etc. The boss becomes their father and their comrades as brothers. The Yakuza offers not only companionship but also money, status, and authority. A part of a group were you feel useful and needed. There are no thresholds or requirements in order to become a member. But when you are inside strict obedience to the superiors is demanded. The yakuza sees himself, as Machi-yakko, the people's rescuer and helper. Far before any working courts existed in Japan the yakuza existed. If your clans chief couldn't or wouldn't help resolve a dispute you could turn to the local yakuza for help. They solved the problem in return for money.
