Dekansho Festival is the official festival organization celebrating the summer traditions of Tamba-Sasayama, Japan. Held over two days each August, it is described as one of western Japan’s largest folk music festivals and a defining feature of the region’s summer season. The event invites visitors to enjoy Dekansho dancing, joining the rhythm with handclaps as performers and participants sing “Dekansho-bushi,” a folk song passed down since the Edo period. The festival aims to create memorable summer experiences while sharing local culture with residents and visitors.

The official website provides practical information about the festival, including an overview, access details, announcements, and contact information. It also offers educational resources through its Dekansho learning section, with song lyrics, instructions for dancing, and material on the song’s history, origins, and name. Visitors can explore historical accounts and learn more about the traditions behind the celebration. The festival is supported by the Dekansho Festival Executive Committee, which handles inquiries and shares updates about event arrangements and activities.
