The half board Japanese meals were one of the best we have had. The onsen was fabulous, especially the outdoor part. Though I should have been mindful that the one called O was opened to public during certain hours. It was a bit crowded during those times. All in all, a lovely stay !

Newer, gorgeous property with Ainu elements at a serene part of the small town. Nice, minimally designed room with great view of the lake, great for a relax trip. Onsen water is brownish and feels v therapeutic, smoothening for the skin.
Food is alright, breakfast portion is a little small. Unlike other similar grade onsen hotels, there is no drinks provided in the room - only a jug of water, this is rather disappointing. Can't be sure the water is fresh. If this is due to environmental practice, the hotel could have provided water in aluminium can...

We had the most gorgeous time at this beautiful ryokan/onsen/resort. The setting is so calm and luxurious – I’ll never forget sitting in the (huge) window of our room in the evening and morning, watching the birdlife over the pond and river, with the snowy mountains in the distance. The outdoor onsen is especially spectacular in the early mornings and late nights, and we appreciated that even at 'busy' times during our stay there were only a handful of other people at most in the onsen. It was also lovely to have information for those new to onsen, so everyone felt welcome and comfortable, and a recommended 'itinerary' for a one-night stay, acknowledging that many (like us) would only have a short time here. Dinner and breakfast were both stunning in the traditional ryokan style, with lovely sake and wine on offer in the evening. The hotel is clearly able to accomodate a large number of guests but is cleverly laid out (as is the dining room) to make it feel very intimate and private for each guest. It’s such a special and calm place, and one I’ll always think of very fondly! (PS. You can access the National Ainu Museum by foot via the hotel car park, or it’s a very quick drive next door. We visited after checking out — not to be missed!)

The friendly staff, their service is outstanding. There is a dedicated person who welcome you, carry your bags, give you a tour of the facility and the room.

The room is clean and comfortable, great amenities, the only thing that I do not like is they blast the heater to high, even with lowering the temperature, it is still very hot.

The room came with dinner and breakfast. I did not tell them in advance that my husband is allergic to diary, So there have no time to amend the menu for dinner. But for the breakfast, they were able to substitute all dishes with diary with alternatives. Service is excellent and over and above.

Two words: the view!! It was one of the best resort we’ve stayed in. An easy 8 minute walk from the train station or 5 min taxi ride. Located next to the Ainu museum. The staff were friendly and super hospitable. When we got there we were assigned a hostess would gave us a tour of the resort and amenities. The outside livable onsen was amazing, relaxing, and had the most beautiful views of the lake and mountains. The insider onsen was nice but it is open to the public so I only went once. But the best was the onsen bath in the room, but warming it is extremely hot like boiling water lol but once you open the window it’s much more pleasant.

Beautiful location, very comfortable room with an onsen in your bathroom. The private open air onsen is wonderful, one of the most peaceful moments of our trip. The hotel is architecturally gorgeous and the way it blends with nature is stunning.
Food is ok, there’s only one restaurant and you have to book breakfast and dinner - otherwise you have to walk to get something to eat as there’s nothing the kitchen can prepare which I find a bit disappointing after several hours traveling and feeling super tired. Dinner was great although for tourists not used to the style there could have been an explanation of the set menu which I found out later there were many dishes I was allergic to and couldn’t change.
Overall is a nice hotel for a one night stay but given above preparation is needed.

The landscape is really beautiful and the spa is also satisfactory.
I just want to mention the quality of the service. The staffs are very kind and sincere, but I don't think the system isn't well-organized. They are all very young, not much-experienced, and it takes much time to get properly served.
For example, I arrived earlier than the schedule, so I checked in and went out to look around. When I came back, I expected to be ushered to my room immediately, but they made me stand in the lobby for 5 mins. or so without further explanation.
The food was a litte experimental, and very slowely served.

入住經驗由一個令人不太愉快的check in開始,還沒有正式開始手續時,已被告知我今晚晚餐時間只有下午5時30分這個選項。向工作人員表達下午5時30分這個晚餐時間並不理想,工作人員幫我向另一個英語表達能力較強且看起來比較資深的工作人員轉達能否調配晚餐時間,該看起來比較資深的工作人員表達不能,我向資深一點的工作人員表達是否我今天check in時間太遲以致我沒有選擇晚餐時間的權利(當時是下午3時30分),工作人員表示不是,那我再詢問原因,工作人員說其他客人已在之前作出網上預訂。我再表示,我並不是透過酒店官網作出預訂,而是經過第三方平台作出預訂,如果晚餐時間是有限制,或用餐理想時間受先到先得限制,理應透過平台提醒住客先作出預訂及時間為先到先得,而不是住客不知就裡來到被告知,你的晚飯時間只有下午5時30分這唯一選項,現在你給我的選項只有一個,我只能接受?資深員工有點輕挑只回一字:Yes。
我也給該名員工回覆一句:Then I don’t accept
該名員工才再幫我向其他人詢問,才幫我改到晚餐為7點半這個時間。
想試問一個在渡假的人誰想在下午5時30分就享用晚餐?請高級品牌星野集團改善這個問題。介紹房間的員工可能英文比較一般,聽完也不知房間有甚麼設備。
房間裝飾及餐膳加入北海道原住民元素令人感到驚喜,此為住宿亮點,請保持這兩個特點。餐點早晚兩餐也非常美味,用餐氣氛及環境令人愉快,餐廳員工有禮且具備相關知識。

酒店質素很好,服務員態度親切及主動幫助顧客 外在不可控因素例如蚊患嚴重 令我對酒店的印象扣了有一些分數。附近亦有齊Coop, Daiso等超巿及商店,走遠些少還有分散疏落的食肆 大多集中在最接近的白老JR駅。開車去的會更好,不開車的就可坐巿內循環巴士。
