Deep in the mountains of Shikoku lies Iya, which is home to a few small settlements. The steep, narrow and misty valley is the stuff of lore. In the 12th century it was a haven for fugitive Heike clan warriors who easily slipped away in the rugged terrain. Over the years, the community has seen its population shrink and age. But a decade ago, Iya became a popular destination for overseas visitors. We visit Iya to find out why and search for hints for regional revitalization.

The Gujo Odori, one of Japan's largest Bon dances, is a spectacle with the 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.
