The Gujo Odori, one of Japan's largest Bon dances, is a spectacle with scores of revelers, as well as the live festival music and clacking geta wooden clogs. For more than 400 years, it has been held for 30 nights from July to September in Gujo-Hachiman, a village located deep in the mountains of Gifu Prefecture. The main event is the all-night dance for four days starting on August 13. French actor Robin Barde explores the deep culture of the festival and dances the night away.
