The first Yosakoi festival was held in 1954 in Kōchi, Kōchi, on the island of Shikoku. Yosakoi-style dancing has spread throughout much of Japan. The style of dance is highly energetic, combining traditional Japanese dance movements with modern music. The choreographed dances are often performed by large teams.
