Yunomine Onsen
Yunomine · Kansai
One of Japan's oldest thermal springs, discovered over 1,800 years ago in a narrow valley of the Kii Mountains along the Nakahechi Trail of the Kumano Kodo pilgrimage route. The waters here are said to change color seven times a day due to shifts in temperature and mineral concentration. Tsuboyu, a tiny stone-lined pool fitted inside a small wooden cabin, is the only UNESCO World Heritage registered bathing site in the world.
