Lake Haruna’s only natural hot spring, Harunako Onsen, is located in a place where you can get a whole view of Lake Haruna which reflects mysterious expressions and beautiful nature. The onsen that flowingly springs out from deep within the ground, has a fine and smooth quality, and is an abundant natural hot spring that is gentle on the skin. You can enjoy a happy moment by getting rid of your fatigue while bathing, relaxing your heart, and being enveloped by happiness with the backdrop of Haruna’s changing expressions with each season. The somewhat cloudy hot spring is abundant, gentle on the skin, and has many benefits. You can enjoy it as a day trip onsen, and the lodging facility is satisfying so you can use it to fit your purposes. How about healing your body with the natural hot spring, along side the beautiful nature you can enjoy with each season at Mt. Haruna, one of the Jomosan mountains?
