Takenoko-zoku
Takenoko-zoku (竹の子族, lit. "bamboo shoot tribe") describes a type of dance group active from the mid-1970s to the mid-1980s in Tokyo, especially in Harajuku. The teenagers, mainly girls but often with one boy leading, were colorfully dressed and danced in a distinctive style on the sidewalk to music from stereos. To an extent, they were precursors to the gyaru groups that would eventually arise in the 90s. A performance of a takenoko-zoku group can be seen in Chris Marker's film "Sans Soleil".
