Tsubo-yu

Tiny rock-carved bath located in the heart of Yunomine Onsen, a village on the Kumano Kodo pilgrimage route. It is significant as the only hot spring in the world registered as a UNESCO World Heritage site. The bath is a small wooden cabin over a natural hot spring hole in the creek bed, accommodating only two people at a time. Because of its small size and immense historical importance, the bath is used in 30-minute private rotations. Travelers must purchase a ticket at the local ticket office and wait for their number to be called. Tattoos are irrelevant here as the bath is entirely private for the duration of your session.
