Chapatsu

Chapatsu (茶髪/ちゃぱつ^?), literally "brown hair" in the Japanese language,^[1] is the once-rebellious, once-trendy style of bleaching (and occasionally dyeing) hair, found among Japanese teens.

The word Chapatsu is formed from two kanji: 茶, meaning "tea" and 髪, meaning "hair".^[1] Chapatsu originally referred to a variety of colors of hair dye, including blonde, red, orange, and blue, it now refers to a brown-tea hue.^[4] 

The style was once banned at Japanese schools and became a widespread topic of the civic right to self-expression, but discussion of the topic died down due to the ubiquity of the style.^[2][3]

Chapatsu came to be allowed as not only young people but also members of society according to the type of business, and it was established before long as one of the Japanese fashions.

While the style itself began to show up in Tokyo streets during the early to mid-1990s, chapatsu was first described in Imidas, an annual publication of new words and concepts in the Japanese language, in 1997. Chapatsu did not appear in Kōjien, an authoritative dictionary of the Japanese language, until 1998.
