Located on the top fifth floor of Kinsenkaku, this large public bath observatory bath, Seijaku-no-Yu and Komorebi-no-Yu, overlooks the rich natural scenery at the foot of sacred Mount Sanage. It uses an extremely rare 100% natural radon source spring, a simple weak radioactive cold mineral spring, which was the first in Aichi Prefecture to receive permission to be served as drinking water. It is beloved as the miracle bath that activates cells and enhances the body’s natural healing power. The bath tubs are made lavishly of cypress, and you can enjoy an exquisite forest bath together with the pure breeze passing through the wood. A drinking spring station is also available in the first-floor lobby.

These three private open-air baths, Hoshimi-no-Yu, Gemini, Sirius, and Altair, let you savor the miracle bath in a supreme private setting. In addition to the ceramic pot bath with bubbling water, where millions of tiny bubbles gently massage your whole body, there are special baths of different styles, such as a large round bath that the whole family can relax in and a bath with a reclined seat, allowing you to luxuriate in 100% natural radon spring water.
