100% Kakenagashi onsen

• 🌡️Two tubs, one hot and one lukewarm, so you can soak the way you prefer.
• 💧The water travels about 8km from the Adatara range through Japan's longest hikiyu pipeline.

An acidic spring, rare in Japan

• 🧪A strongly antibacterial acidic spring, long said to help with chronic dermatitis and atopy.
