Around Lake Mashu × Stays Popular For Snow-View BathsHighly-rated Hotel·Ryokan

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.

This was my third stay here, as part of a summer training program. The hot spring water is simply wonderful, but it seems the Facilities can be damaged because of it. There was a handwritten note explaining the reasons—such as how it relates to the spring’s mineral content—and it felt thoughtfully handled. This year I chose a plan without meals, so I can’t comment on the food. During this stay, I accidentally left something behind in my Room, and I truly appreciate how warmly and kindly you responded to my request. Thank you very much. I’d love to visit again someday during the colder season.

Recommended by a gourmet friend, I stayed at this accommodation. Having lived in Eastern Hokkaido before, I had visited the surrounding area often but was not very familiar with Lake Kussharo. Curious about the place, I decided to visit and was immediately impressed by the stunning mountain views from the lodge. The rare snowfall for this region added to its charm this year. The experience of checking in via canoe or snowshoe from Lake Kussharo was truly memorable. The accommodation building featured facilities such as a sauna, cold bath, and barrel bath. It was delightful to cool off while enjoying the snowy scenery after using the sauna. For the first time, I also experienced tending a fireplace with firewood, which allowed me to spend mindful and relaxing moments. The meals were Chinese-inspired cuisine and absolutely delicious! The chef skillfully prepared luxurious ingredients like abalone and shark fin for an unforgettable dining experience. Thank you for kindly preparing additional mapo tofu as well—it was fantastic! Breakfast was equally exceptional. While having dinner, it started snowing outside; we appreciated how staff thoughtfully cleared snow just before we returned to our room in the accommodation building. Although it would be nice if improvements could be made regarding some minor points—such as whether or not the baths are onsen or addressing slight odors in rooms with toilets and showers—the overall experience far outweighed these small concerns. It left such an impression that I ended up making a summer reservation before leaving! This place is truly remarkable—I look forward to visiting again during another season for more unique experiences. Thank you so much for providing such precious memories!

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.

Right in front of Lake Kussharo—an unbeatable location. Rera is built diagonally in front of Fre, so you may be a bit aware of each other’s presence, and I did wonder what it would feel like if someone walked by while I was in the bath. The view from the second floor is simply stunning. The ingredients for the meals are luxurious and delicious, but unfortunately the wine selection didn’t match our taste (it would have been nice if at least the grape varieties were listed). Despite the overall great sense of style, there were some everyday-looking items like hand soap placed in the washroom, which slightly took away from the atmosphere. There was a faint damp smell on the towels, and the indoor slippers felt too ordinary—disposable ones might actually be better.

A lovely pension by Lake Kussharo. The highlight is the hard French bread, which rivals those from famous city bakeries. The meals were impressively delicious, especially considering they are self-taught, and I appreciated that proper tea was served alongside coffee. The onsen with an open-air bath was excellent. Kotan no Yu was also nearby. Although we couldn't secure a canoe reservation during the busy Obon season this time, we look forward to enjoying the enchanting winter canoe tour in the future.

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.

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.

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.
