Oboke and the downstream community of Koboke are connected by a deep gorge which the plunging River Yoshino has carved out of the rock on its way through the Shikoku mountains. It is a place that every traveler over these mountains must traverse and has been known as a perilous stretch since olden times.
Sliding Door Theater
A traditional performing art has been revived at the Shisho Shrine in the Ushiroyama neighborhood of Nishi Iya after a gap of 50 years. A set of painted sliding doors 10 deep is manipulated to present a splendid series of changing scenes. The Tokuzen neighborhood of Nishi Iya also has its own sliding door theater conservation society.
