Hokkaido Nakashibetsu Town
A free-flowing natural hot spring inn where, after the sauna, you immerse yourself in the clear stream
"Yuyado Daiichi" is a hot spring ryokan in Nakashibetsu, Hokkaido. Nestled in deep forest beside the clear waters of the Shibetsu River, it offers a rock-built mixed-gender open-air bath with almost no barrier between the bath and the river, creating the feeling of becoming part of nature itself. In the men's bath, there is a log-style bath carved from Canada spruce that is several hundred years old, while the women's bath features an open-air rock bath built from stacked stones. Both are fed by free-flowing natural hot spring water straight from the source. With 6 saunas in total for men and women, it won the 2025 Grand Prix in Sauna Shuran, Japan's largest sauna award. Among them, the sauna where spring water cascades inside like a waterfall is a room filled with humid heat under constant löyly, with the Shibetsu River visible through a large window. Once you've built up the heat, you can immerse yourself directly in the river flowing right next to the open-air bath.

A large bathing area combining indoor and open-air baths. In the men's bath, there is a custom-made log bath carved from Canadian spruce that is several hundred years old, with the warmth of the wood and the fragrance of the water rising together. The women's bath features an open-air rock bath built from natural stone, where you can soak while listening to the murmuring of the mountain stream and the songs of wild birds. The water is a natural hot spring of sodium-calcium chloride sulfate spring. The free-flowing water smooths the skin and leaves warmth lingering long after you get out.

The signature sauna of this inn, available in both the men's and women's baths. Inside, spring water continues to pour down like a waterfall, and its heat rises as steam, so without anyone pouring water, the room stays in a constant state of löyly. The soft air, rich with moisture, wraps around your whole body, and with each breath the warmth reaches deep into your core. Through the large window, the Shibetsu River flows by, letting you enjoy the view of the clear stream all to yourself while you surrender to the heat.

A steam sauna filled with white vapor. The air, warmed by hot water, gently envelops your skin, and each deep breath softly moistens the back of your throat. There is no sense of being driven out by the heat, and as you sit, the stiffness in your shoulders and neck gradually loosens. Fragrant with hot spring water and quiet like the forest, it offers a calm flow of time.

A dry sauna in the men's indoor bath named after the Blakiston's fish owl, the inn's symbol. A convection stove piled with sauna stones steadily heats the room, and the steam rising from löyly drives the heat deep into your body with every breath. True to its name, it is a quiet setting with no unnecessary light or sound. As you close your eyes and give yourself over to the heat, your awareness slowly sinks inward.

A wood-fired sauna made from a converted trailer, set in the men's outdoor area. The heat rising with the crackle of burning logs feels wild in a way that electric heat never can, enveloping your body with a thickness and fluctuation of warmth. Self-löyly is possible, and each time water is poured onto the stones, white steam swells all at once, mingling the scent of wood with the smell of fire. In this small box outdoors, a dense stretch of time passes as you face only the presence of the forest and the heat of the flames.

A cold plunge bath placed directly in front of the indoor sauna exit. It is deep enough to let you sink in up to your shoulders while standing, so your heated body is enveloped in coolness without missing a spot. Because it is filled with hot spring water that has been cooled, its touch on the skin is gentle, allowing you to stay immersed for a long time without holding your breath. You can savor the sensation of heat slowly leaving your body in the quiet indoor bath.

A cold plunge bath located just outside the outdoor sauna area. Spacious enough for several people to enter side by side, it lets the cold and the wind draw heat away at the same time as you lower your body into the water. Since it is filled with hot spring water that has been cooled, the touch on the skin is soft, and even while immersed, your breathing stays steady. With the sky open overhead, air carrying the scent of the forest passes over your cooling body.

You can lower yourself directly into the river flowing right beside the open-air bath. The heat stored up in the sauna collapses the moment it meets the endlessly flowing clear water, and an overwhelming rush of refreshment runs through your entire body. Rather than a tank with temperature controlled by people, nature itself, changing with the seasons, becomes the cooling system. Even in midsummer, your body tightens to the core, and in winter, a breath-stopping cold awaits. This is a unique cold bath that exists only here, and nowhere else.
