Yosakoi Matsuri

The Yosakoi Matsuri, held every August in Kochi City, Kochi Prefecture, is one of postwar Japan's most iconic modern festivals. It began in 1954, organized chiefly by the Kochi Chamber of Commerce and Industry, with the aim of dispelling the gloom of the postwar economic slump and lifting the spirits of the city's residents. It is said to have been conceived partly in friendly rivalry with the famous Awa Odori of neighboring Tokushima. The first festival drew 21 teams and around 750 dancers.

The name "Yosakoi" derives from "Yosakoi Bushi," a traditional folk song of Kochi. The festival's defining feature is the naruko, a wooden clapper held in each dancer's hands. Originally an agricultural tool used to scare birds away from rice fields, the naruko was reimagined as a rhythm instrument by composer Eisaku Takemasa, becoming the festival's enduring symbol.

What fueled Yosakoi's explosive growth is its remarkable openness: as long as dancers hold naruko and move forward, and as long as a phrase of "Yosakoi Bushi" is woven into the music, every team is free to choose its own music, choreography, and costumes. This flexibility allowed teams to incorporate rock, samba, folk, and countless other styles.

Each team performs led by a jikatasha—an elaborately decorated sound truck—dancing through competition stages and performance venues scattered across the city. The powerful group choreography, performed by dancers in vividly colored costumes clapping their naruko in unison, electrifies spectators.

Today the festival features around 200 teams and some 20,000 dancers, ranking among the three great festivals of Shikoku. As the original source of the "Yosakoi-style" festivals that have since spread across Japan and around the world—most notably the YOSAKOI Soran Festival in Sapporo—its influence remains profound and undiminished.
