Yakuza

Yakuza (ヤクザ or やくざ ), also known as gokudō (極道), are members of traditional organized crime syndicates in Japan. The Japanese police and media, by request of the police, call them bōryokudan (暴力団), literally "violence group", while the yakuza call themselves "ninkyō dantai" (任侠団体 or 仁侠団体), "chivalrous organizations".

Burakumin

The Burakumin are a group that is socially discriminated against in Japanese society. The burakumin are descendants of outcast communities of the feudal era, mainly those with occupations considered tainted with death or ritual impurity, such as butchers, executioners, undertakers or leather workers. They traditionally lived in their own secluded hamlets and ghettos. Discrimination against the Burakumin continues into the present day, a legacy of the Japanese feudal/caste system.
According to David E. Kaplan and Alec Dubro, burakumin account for about 70 percent of the members of Yamaguchi-gumi, the largest Yakuza syndicate in Japan.
Mitsuhiro Suganuma, ex-officer of the Public Security Intelligence Agency, testified that burakumin account for about 60 percent of the members of the entire Yakuza.

Structure

During the formation of the yakuza, they adopted the traditional Japanese hierarchical structure of oyabun-kobun where kobun (子分; lit. foster child) owe their allegiance to the oyabun (親分; lit. foster parent). In a much later period, the code of jingi (仁義, justice and duty) was developed where loyalty and respect are a way of life.

The oyabun-kobun relationship is formalized by ceremonial sharing of sake from a single cup. This ritual is not exclusive to the yakuza—it is also commonly performed in traditional Japanese Shinto weddings, and may have been a part of sworn brotherhood relationships.
During the World War II period in Japan, the more traditional tekiya/bakuto form of organization declined as the entire population was mobilised to participate in the war effort and society came under strict military government. However, after the war, the yakuza adapted again.
Prospective yakuza come from all walks of life. The most romantic tales tell how yakuza accept sons who have been abandoned or exiled by their parents. Many yakuza start out in junior high school or high school as common street thugs or members of bōsōzoku gangs. Perhaps because of its lower socio-economic status, numerous yakuza members come from Burakumin and ethnic Korean backgrounds.
Yakuza groups are headed by an Oyabun or Kumichō (組長, family head) who gives orders to his subordinates, the kobun. In this respect, the organization is a variation of the traditional Japanese senpai-kōhai (senior-junior) model. Members of yakuza gangs cut their family ties and transfer their loyalty to the gang boss. They refer to each other as family members - fathers and elder and younger brothers. The Yakuza is populated almost entirely by men, and there are very few women involved who are called "nee-san" (姐さん older sister). When the Yamaguchi-gumi (Family) boss (Kazuo Taoka) died in the early 1980s, his wife (Fumiko) took over as boss of Yamaguchi-gumi, albeit for a short time.

Rituals

Yubitsume, or the cutting of one's finger, is a form of penance or apology. Upon a first offence, the transgressor must cut off the tip of his left little finger and hand the severed portion to his boss. Sometimes an underboss may do this in penance to the oyabun if he wants to spare a member of his own gang from further retaliation.
Its origin stems from the traditional way of holding a Japanese sword. The bottom three fingers of each hand are used to grip the sword tightly, with the thumb and index fingers slightly loose. The removal of digits starting with the little finger moving up the hand to the index finger progressively weakens a person's sword grip.
The idea is that a person with a weak sword grip then has to rely more on the group for protection—reducing individual action. In recent years, prosthetic fingertips have been developed to disguise this distinctive appearance.
Many Yakuza have full-body tattoos. These tattoos, known as irezumi in Japan, are still often "hand-poked", that is, the ink is inserted beneath the skin using non-electrical, hand-made and hand held tools with needles of sharpened bamboo or steel. The procedure is expensive and painful and can take years to complete.
When yakuza members play Oicho-Kabu cards with each other, they often remove their shirts or open them up and drape them around their waists. This allows them to display their full-body tattoos to each other. This is one of the few times that yakuza members display their tattoos to others, as they normally keep them concealed in public with long-sleeved and high-necked shirts. When new members join, they are often required to remove their pants as well and reveal any lower body tattoos.
