Zoku(族) is a Sino-Japanese term meaning tribe, clan, or family. As a suffix it has been used extensively within Japan to define subcultural phenomena, though a large number of zoku don't acquire the suffix (e.g. cosplay).
A zoku might be labelled with a Japanese stem (e.g. kaminari zoku) or a foreign language (gairaigo) stem (e.g. saike zoku, where saike comes from "psychedelic").
Historic groups labelled as Zoku
Subcultures that emerged in the early post-war decades include the "motorcycle-riding Thunder Tribe (kaminarizoku), the amplified-music-loving Electric Tribe (erekizoku), and the Psychedelic Tribe (saikezoku)."
Shintaro Ishihara's 1950s novel Season of the Sun gave rise to a reckless and carefree expression of youth which became stylised in subsequent films as taiyo zoku (sun tribe). This subculture had a few parallels with the rocker and greaser subcultures being promoted by Hollywood films such as Rebel without a Cause. Traditional Japanese considered the post-war taiyo zoku violent and promiscuous. Some Japanese youths admired American music, and Japanese Bill Haley clones were known as rokabiri zoku (the rockabilly tribe).
At the height of the hippy movement and the psychedelic age in the 1960s, the futen zoku or vagabond tribe emerged in the Shinjuku area of Japan. Japanese media depicted them as dangerous because of their substance abuse and their public presence. More recreational drug users who patronised clubs and coffee shops were known as danmo zoku.
A 1970s Japanese punk movement was known as karasu zoku (crow tribe) because they wore black clothing and accessories. Young women readers of the 1970s magazines "an an" and "non no" were known as the an-non zoku.
In the 1980s, fashion became mixed with music and dance in the form of the takenoko-zoku or (bamboo-shoot tribe). This subculture was named after a boutique in Harajuku. Other parts of Tokyo such as Roppongi and Ginza have been centres of Japanese popular culture, and a large number of zoku have been named after sites in these localities.
Another quite significant group of the 1980s was the kurisutaru zoku (crystal tribe), which were branded a social group after the success of the novel Nantonaku Kurisutaru (Somewhat Crystal). This label applied to youth who were swept up in the freedoms of the economic boom of the 1980s and became materialistic and conscious of their image, much like yuppies. They have been contrasted with the rougher groups that had existed after the 1950s.
The Hanako zoku of the late 1980s was associated with a popular magazine for young women called Hanako.
