Ishite-no-Yu
A natural hot spring drawn through pipes from Okudogo Onsen. Known for its soft alkaline waters that leave the skin smooth, it is a beauty-enhancing bath. There are indoor and open-air baths, with the open-air bath offering a sense of openness with views of Matsuyama Castle. The view from the top floor, the 13th floor, along with the carefully designed stone arrangements and lighting, further enhances the quality of the hot spring. After bathing, your body feels relaxed, and it is expected to be effective for joint pain, cold sensitivity, and shoulder stiffness. During the day, the light reflecting off the water surface is beautiful, and at night, Matsuyama Castle is illuminated until 11 PM.
