Hokkaido Noboribetsu City
Noboribetsu’s stately house of welcome, where the Oni Sauna and three celebrated springs melt body and mind
Noboribetsu Grand Hotel is a long-established hotel in Noboribetsu, Hokkaido. Even in Noboribetsu, one of Japan’s most celebrated onsen towns, it stands out for letting you enjoy three kinds of natural onsen at once: a sulfur spring, a sodium chloride spring and an iron spring. It is also well known as a serious sauna destination, with a high-temperature sauna with automatic löyly where you can feel overwhelming heat in a garden overlooking a waterfall, as well as a hushed meditation sauna. The cold plunge, filled with natural water, delivers an otherworldly cool-down and a deep sense of totonou, the state of deep relaxation that follows the heat and the cold.

This bath combines an airy, dome-shaped Roman-style main bathhouse, where soft sunlight pours in through a skylight at the top, with a garden open-air bath that looks out over a powerful waterfall close at hand. As you make your way around Noboribetsu’s three celebrated waters, a sulfur spring, a sodium chloride spring and an iron spring, you can enjoy the contrast between a historic modern-style space and the untamed beauty of nature.

Here a dome-shaped main bathhouse, whose ceiling lines radiate outward and still carry the modern feel of the hotel’s early days, is paired with a garden open-air bath built around bold, rugged stones. After giving yourself over to the three celebrated waters in the indoor baths and warming up to the core, head out to the open-air area with its fragrant hinoki bath and rock bath. Feel the clear breezes of each season on your skin as you enjoy a deeply relaxing time.

A private open-air bath set on the terrace of your room. The tub is filled with a mellow artificial onsen made with radium mineral spring water, and you can enjoy a luxurious soak all to yourselves, whenever and for as long as you like, as the pleasant breezes of each season brush your skin.

Found in Hozuki-no-Yu, this extremely hot sauna is themed on the oni, the ogre that is the symbol of Noboribetsu, and boasts overwhelming heat. Automatic löyly fills the room with powerful, superb steam, and sweat pours from your whole body almost instantly. Surrounded by rugged rock walls that call to mind an oni’s lair, it offers a weighty, thrilling sauna experience you will not find anywhere else. *Open to women on odd-numbered days and to men on even-numbered days.

A medium-temperature sauna in Hozuki-no-Yu, made for meditation and relaxation. You can pour löyly yourself and whisk yourself, and the pleasant scent of vihta from Hokkaido gently fills the room. With the sound of a quietly flowing waterfall in the distance and the warmth of wood all around, you can spend a superb stretch of meditation time as body and mind slowly unwind. *Open to women on odd-numbered days and to men on even-numbered days.

A newly built, gentle medium-temperature sauna in Rindo-no-Yu where you pour löyly yourself. You can take your time and warm up from deep inside, and because it never feels stifling, it is ideal for sauna beginners and anyone who wants to take things slowly. Pouring löyly yourself keeps the humidity just right, and the room is designed so that fine steam wraps gently around your body. *Open to women on even-numbered days and to men on odd-numbered days.

Set in the open-air area of Hozuki-no-Yu, this cold plunge takes the form of a blue hagama rice cauldron, inspired by the cauldrons of hell. Filled with clear mountain stream water from Noboribetsu, it is a compact tub for one, so you get the water all to yourself. It fits snugly around your body and refreshingly cools you down after the fierce heat of the Oni Sauna. You can also alternate between hot and cold with the red hagama next to it (hot water at 43–44°C (109–111°F)).

In the open-air area of Hozuki-no-Yu, this cold plunge draws you in with its crisp, thoroughly chilled water. It is filled with fresh mountain stream water and sits right by the sauna room, so the route between them could hardly be better. You can go straight from the hot sauna into the cold plunge in one smooth motion, and in moments the cold pulls the body taut with a sharp, clean chill.
