An indoor bath that luxuriantly overflows with 100% natural flowing Dake Onsen spring water from the spring outlet, using the mixed water from the five original springs of the hot spring area at pH2.5, with absolutely no dilution, heating, or recirculation. The pure white bath sediment gathered at the bottom turns into a beautiful milky bath with an emerald-green tint when stirred, bringing exceptional moisture and skin-beautifying benefits.

A spectacularly open milky open-air bath where you soak while looking up at the unobstructed, spacious blue sky of Adatara. The water is drawn from about 8km away from the slopes of Mount Adatara to Dake Onsen, and being hand-stirred gives it a gentle, soft texture that is kind to the skin. With an exquisite water temperature that feels wonderful even for a long soak, it is a relaxing place where you can feel the breath of nature.

A spacious private bath where you can feel the rich deciduous forest nature of Adatara right beside you (fee required, reservation only, 45 minutes per session, ※not a hot spring, heated water only, closed in winter). A special space where you can enjoy a leisurely private bath with your companions or family while basking in dappled sunlight, without worrying about anyone else.
