Yosakoi Dance Festival is held annually at Tokyo's Harajuku district, a center of young people's fashion and culture in Japan.

Yosakoi is a traditional summer dance that originated in Japan. It is a highly energetic dance which combines traditional Japanese dance movements with modern music. The choreographed dances are often performed by large teams. Yosakoi participants include men and women of almost all ages – sometimes within a single team of less than 150 members.

One of the defining aspects of yosakoi dance is the use of naruko: small wooden clappers that are held in the hands of each dancer.
