Kōmyōseki Hot Spring
An artificial hot spring in the indoor bath that uses Kōmyōseki, a natural mineral stone approved by the Ministry of Health, Labour and Welfare. By passing the water through Kōmyōseki, which is said to have exceptionally strong ionizing properties, the bathwater becomes very soft and mild. Rich in minerals, the water is gentle on the skin, absorbs smoothly, and helps warm the body thoroughly from the core. It is a bath where benefits for neuralgia, stiff shoulders, and sensitivity to cold can be expected, and after bathing, its comforting warmth and moisturizing feel linger pleasantly.
