The private source, Asaya Spring (Kodakara no Yu), can be enjoyed in the large baths of Shuho-kan and Hachiban-kan. Its gentle feel on the skin comes from an alkaline simple hot spring that wraps the body softly. Long known as a famous spring associated with the saying, "Brought by burns, lost by injury, healed in Kawaji," it is expected to be especially effective for fatigue recovery, beautiful skin, and improving poor circulation. In the spacious tubs, you can luxuriate in the historical hot spring of Kinugawa and fully savor a truly indulgent time.

Located on the 13th floor of Shuho-kan, this is the highest open-air bath in Kinugawa Onsen. While soaking in the private spring, you can gaze out at the mountains of Kinugawa spreading before you, the clear sky, and at night, a sky full of stars. In an overwhelming sense of openness, you can feel the breeze and be soothed by a famous hot spring, making for a supreme bathing experience that can only be enjoyed here.

At Asaya Hotel, the in-room observation baths and open-air baths are also fed by the property’s own hot spring source. The guest room baths are luxurious free-flowing source baths, allowing you to have the fresh, famous water all to yourself whenever you like in a private space. This is an exquisite private spa where you can enjoy the hot spring to your heart’s content without interruption, while taking in the beauty of the Kinugawa valley and the pleasant breeze.
