Japan is famous for the young people tribes. Let’s take a look:
Gyaru:Japanese transliteration of the English word gal brand of . The name originated from a 1970sjeans called “gals”, with the advertising slogan: “I can’t live without men”, and was applied to fashion- and peer-conscious girls in their teens and early twenties. Its usage peaked in the 1980s and has gradually declined. The term gradually drifted to apply to a younger group, whose seeming lack of interest in work or marriage gained the word a “childish” image. It is now used almost interchangeably with kogyaru and younger generations may consider it clichéd or even archaic. (from wikipedia)
Yamanba (ヤマンバ), is a newer term often used to describe extreme practitioners of ganguro fashion. Yamanba feature darker tans and add white lipstick, pastel eye makeup, tiny metallic or glittery adhesives below the eyes, brightly-colored contact lenses, plastic dayglo-colored clothing, and incongruous accessories to the ganguro look. Some yamanba wear stuffed animals as decorations. The male equivalent is called a “center guy” (センター街 Sentaagai?, Center Street), a pun on the name of a pedestrian shopping street near Shibuya Station in Tokyo where yamanba and center guys are often seen.
Ganguro (ガングロ) is an alternative fashion trend among young Japanese women which peaked in popularity around the year 2000, but remains evident today. The Shibuya and Ikebukuro districts of Tokyo are the center of ganguro fashion.
