Yumoto Kumegawa Onsen is located in Ena, Gifu Prefecture, Japan. Its iron-rich thermal water reaches 42°C, pH 6.3. An indoor bath, an outdoor rotenburo and a sauna round out the facility.
Insider tip — Nestled in the mountainous Gifu prefecture, Yumoto Kumegawa Onsen draws iron-rich waters from deep geothermal sources. The rustic setting amid forested hills makes for a tranquil retreat from the cities of the Chukyo region. The mineral content gives the water a slightly amber tint and a velvety feel on the skin. Local ryokan guests often have exclusive early-morning access before day visitors arrive.
