The Yakuza Society in Japan [JPN39827.E]

According to an article in the Organized Crime Registry, the Yakuza, or "Japanese Mafia", is an all men's society of individuals who are involved in unlawful businesses such as gambling, drugs, prostitution and loan-sharking (n.d.).

An article in The Crime Library describes the organization of the Yakuza Society as follows:

Current Yakuza members fall under three general categories: tekiya (street peddlers), bakuto (gamblers), and gurentai (hoodlums).
The yakuza are proud to be outcasts, and the word yakuza reflects the group's self-image as society's rejects. In regional dialect, ya means 8, ku means 9, and sa means 3, numbers that add up to 20, which is a losing hand in the card game hana-fuda (flower cards). The yakuza are the "bad hands of society"...
Like the Mafia, the yakuza power structure is a pyramid with a patriarch on top and loyal underlings of various rank below him.
The guiding principle of the yakuza structure is the oyabun-kobun relationship. Oyabun literally means "father role"; kobun means "child role." When a man is accepted into the yakuza, he must accept this relationship.
The levels of management within the yakuza structure are much more complex than the Mafia's. Immediately under the kumicho (supreme boss) are the saiko komon (senior adviser) and the so-honbucho (headquarters chief). The wakagashira (number-two man) is a regional boss responsible for governing many gangs; he is assisted by the fuku-honbucho, who is responsible for several gangs of his own. A lesser regional boss is a shateigashira, and he commonly has a shateigashira-hosa to assist him. A typical yakuza crime family will also have dozens of shatei (younger brothers) and many wakashu (junior leaders).
If a yakuza member displeases or severely disappoints his boss, the punishment is often yubizume, the amputation of the last joint of the little finger. A second offense will require the severing of the second joint of that finger, and additional offenses might require moving on to the next finger.
In the past, choice recruits came from the traditional bakuto (gambler) and tekiya (peddler) classes, but today a rebel spirit and a willingness to commit crime for an oyabun is all that is necessary to join the yakuza ranks. Most new members currently come from the bosozuku (speed tribes), street punks known for their love of motorcycles.
This lowering of standards has led to the Japanese National Police Agency adopting the term boryokudan (the violent ones) for the yakuza, lumping them in with other criminal groups. The yakuza, who treasure their ancestral ties to the old samurai, reject the term and consider it an insult (10 Jan. 2002).

According to an article on the MSNBC Web site, the Yakuza are involved in high-level financial fraud, extortion and bribery of politicians (31 Aug. 2002). The biggest yakuza group in Japan is the Yamada gumi (Organized Crime Registry n.d.).
