Is the term used to describe Japanese youth culture who cos-play or 'constume play' on Sundays in the district of Harajuku. Seen as rebels to conformity, Harajuku is a popular place for them to show off their own creations and usually pose for others. Syles include Gothic, Lolita, anime/manga based or futuristic.
