Hot springs in Yunomine
Yunomine, Kansai · Japan
Yunomine Onsen is one of Japan's oldest thermal spring systems, nestled in a deep valley within the Kumano mountain range. Known for its UNESCO World Heritage site, Tsuboyu Bath, this onsen town offers a unique experience with its small, stone-lined soaking pool that fits only one or two people at a time. Legends speak of the 'miraculous healing' properties of its waters, which are said to change color seven times daily and were discovered flowing from a statue of Yakushi Nyorai, the Buddha of healing. The town's spiritual allure is enhanced by its connection to the Kumano Kodo Pilgrimage Route, attracting visitors seeking both relaxation and cultural enrichment. Spring (March-May) or autumn (September-November) are ideal for visiting Yunomine Onsen due to mild weather and beautiful natural scenery. These seasons offer comfortable temperatures for exploring the onsen town and its surroundings.
