A sky high open-air bath overlooking Lake Toya and a top-floor sauna with spectacular views

Hokkaido Toyako Town

"Toya Kohantei" is a hot spring inn in Toyako Onsen, Hokkaido, boasting magnificent lake views. From the "sky high large bath" on the 9th, the top floor, and the "sky high open-air bath" seemingly floating dozens of meters above the lake surface, you can enjoy a luxurious soak while taking in sweeping, unobstructed panoramas of Lake Toya, Nakajima, and the stunning silhouette of Mt. Yotei. The compact dry sauna, shared by both men and women, also has a small window with a view of the timeless Lake Toya, and together with the very cold cold plunge bath supplied with free-flowing tap water, it creates a luxurious hot-and-cold alternating bathing experience.

Hot Spring & Bath Information

Toyako Onsen

TypeNatural Hot Spring

A top-floor hot spring where you can enjoy a famous, abundant spring together with the overwhelming natural beauty of the surrounding lake and mountains. The spring quality includes sodium, calcium-chloride, and sulfate, and bathing leaves salt on the skin, helping prevent sweat from evaporating. Known as the "warming bath" and "heat bath" because it is difficult to cool down afterward, it is highly regarded for its excellent benefits for fatigue recovery and neuralgia. Soaking while gazing up at a sky full of stars from the sky high open-air bath will be an unforgettable experience.

A compact, calm two-level Metos dry sauna attached to the large bath on the 9th, the top floor. There is no TV, and the dim room is gently filled with quiet, soothing Japanese-style BGM. A small window lets you look out over the seasonal autumn leaves of Biei, Lake Toya, and the beautifully rising ridgeline of Mt. Yotei. While imagining the panoramic view, you can fully enjoy a satisfying sweat in the pleasant dry heat.

A compact cold plunge bath installed right next to the large bath sauna, with enough space for two people to enter at the same time. Cool water is continuously supplied from the faucet in a free-flowing stream, and the water temperature is extremely cold at around 10 degrees Celsius (varying from around 8 to 14 degrees depending on the season and weather). It instantly tightens and refreshes the body after sauna use, delivering the ultimate cooldown. Outdoor air bathing from the plastic chairs in the open-air area is exceptionally pleasant.
