마슈산 (카무이누프리) 주변 × 눈 구경 목욕으로 인기 있는 숙소온천・목욕 평가가 높은호텔·료칸

After enjoying canoeing in Kushiro, we arrived and were immediately impressed by the spacious, beautiful entrance. The lobby, centered around an irori hearth, felt wonderfully open and soothing with its charming design. Every member of the staff was truly welcoming, making our stay relaxing and comfortable. The milk soft-serve and milk were rich and flavorful, and the morning daifuku and ozenzai were also delicious. This is our number one Accommodation we’d love to visit again.

Free drink bar (including alcohol), plus post-bath ice bars and probiotic drinks, and manga. Amazing! The bath water quality is great, and the rooms are clean. An Onsen stream runs alongside the Hotel and is beautifully illuminated. Dinner was a buffet, and they even had meaty snow crab. I couldn’t help but overeat. A highly recommended Accommodation.

I’m from Chiba Prefecture. I love Kawayu Onsen and have visited many times. There are high-, medium- (open-air), and low-temperature baths, and every one feels wonderful. During Silver Week, I really wanted my elderly mother to experience this onsen, so we traveled together from Chiba for 3 nights and 4 days. She had said she couldn’t travel anymore, and although I persuaded her to come, she ended up loving the onsen and was truly happy we made the trip. She also ate well and seemed to regain her energy. Thank you for accommodating our requests when I left a note at the time of booking regarding the room location. It was an unforgettable, wonderful stay. Thank you very much.

I stayed for 3 nights and 4 days with my grown son. I’ve stayed at many Accommodations, but SANSUI stands out for its exceptional balance of “closeness to nature,” “freedom during the stay,” and “quality of the setting.” It felt like a rare Accommodation where you don’t get tired even on a longer stay. Bringing our own ingredients, cooking with the provided tableware and tools, and enjoying freshly brewed coffee while looking out over Lake Kussharo and the forest was truly an experience of “staying as if you live there.” The sauna and outdoor Onsen were perfectly arranged in both temperature and flow, and being surrounded by natural sounds allowed both body and mind to fully unwind. At night, the starry sky and the flicker of the campfire were breathtaking. My husband and son thoroughly enjoyed canoeing, and each of us was able to spend time with nature at our own pace. The owner maintains an ideal sense of distance—quietly supportive only when needed—respecting privacy while providing reassurance. The philosophy of the Accommodation is consistent down to every detail, and I felt a deep professionalism in their approach that never interferes with guests’ experiences. The provided shampoo and conditioner from a Hokkaido brand were also excellent—I liked them so much that I bought them as soon as I got home. This is a place where nature’s stillness, the presence of the building, and thoughtful management are beautifully in harmony, making me genuinely want to return in another season.

First stay. Everything was average, neither good nor bad. I used the onsen late at night and early in the morning, and it was empty, so I had it all to myself. The water temperature was perfect, and I was very satisfied. It was disappointing that there was no shop and the selection of souvenirs was limited.

This is a retro Showa-era Hotel (Ryokan). The covered, spacious garage used as a motorcycle parking area was great in rainy weather and for security.

The Accommodation offered convenient access in all directions, delicious meals, and excellent value for money. Recommended if you don’t mind that the Room does not have a private toilet or washbasin. The only drawback was that the Wi-Fi was not provided by the Facility, but via an external free Wi-Fi service (with a time limit). If that doesn’t bother you either, we recommend it.
