This is a wonderful Hotel with great staff. The rooms are spacious, well appointed and clean. The location means that the shuttles are needed to reach the ski fields. During the day I would describe the shuttle service adequate. I believe that there needs to be a few more services during the evening for those looking to visit the other restaurants and villages.

We had a lovely ski holiday staying at One Niseko Towers. Here is what we thought about the hotel.
1) Good access to both Moiwa and Annupuri resorts
Moiwa is walking distance away (walk to – ski back) and there are regular free shuttle bus services to Annupuri. I would say it is a little bit far to Hirafu and as someone else said, the shuttle bus to Hirafu gets you in a bit late. We have trouble choosing which of the resorts are our favourite: Moiwa is so quiet it is almost like a private resort while Annupuri has wide sweeping pistes and the adorable Paradise Hut café!
2) Rooms were large and well equipped
Four of us stayed in an apartment style room. By Japanese standards it is huge! The beds were comfortable (according to my husband, who is very fussy about mattresses and pillows) and there is a kitchenette for cooking simple dinners. It is a Japanese style kitchen so there is no oven but a good hob and gigantic fridge. Pretty fast Wifi in the rooms too. They will properly clean your room once during a week with daily cleaning being minimal (bed making, towel changes and rubbish removal) though this was not an issue for us as we spent most of the day outdoors. The rooms were quiet too and we were lucky enough to get a 10th floor room with beautiful views over the forests.
3) Onsen baths for soothing the aching muscles
The onsen is one of the best features in our family's opinion! Some family members would visit twice a day…. There is a men's and a women's onsen which both have indoor and outdoor baths. It is really nice sitting outside in a hot bath while looking at the snow. I would add that the onsen as well as a lot of the public spaces are decorated in a simple contemporary style. We liked the calming non-fussy stylish look.
4) Good breakfast and Tura
We had a package including breakfast. There are choices of Japanese, Western and Chinese breakfast dishes all cooked well. My children would pile their trays high with croissant, miso soup, scrambled egg and fried chicken…? I think I saw reviews commenting on the quality of coffee but we found the espresso on the coffee machine pretty good. It is not artisanal flat white of course but we weren’t in Niseko for the coffee. There are capsule type coffee machines in the rooms too which were very much like nespresso. As someone else said, the Tura restaurant is highly recommended. It is a bit expensive so we only went once during our stay but we very much enjoyed the course menu. The standard of cooking is extremely high. For example, our favourite dishes were crispy pan friend oysters with oyster risotto and grilled Hokkaido pork with a Japanese sauce. When we visited Tura it was empty apart from us. Don’t let this put you off. It will be important to book a table and preferably specify what you will eat in advance so they are ready. We did not try the room service.
5) Friendly service
Last but not least the service at One Niseko was wonderful. There are a lot of young non-Japanese people on working holiday so if you want to communicate in English, this is not a problem at all. Various requests we had (e.g. securing airport shuttle bus seats last minute, fixing the safe in the room, borrowing wine glasses from the bar) were met with a smile and can-do attitude. The day we arrived dragging bags up the parking lot, we were surprised by many hotel staff hurrying down to take our bags. Maybe they were there coincidentally but there seemed to always be a stance that they will help guests as much as possible. Some of the young non-Japanese staff we spoke to seemed genuinely pleased to have been selected to work there with the opportunity to enjoy the snow in their free time, learn Japanese and make international friends. It gave the impression that the hotel management are doing a good job at hiring, training and motivating staff and this can only be a good thing for us guests whose stay is influenced by the people looking after us.

We hope to stay again at One Niseko!

Good hotel, which is especially worth also for its quality catering (you have to try the Tura) and its team (Mr Taro and Kuan in particular). Main fault: the shuttle. impossible to be at 9 am in Hirafu, while the United Shuttle is only 5 minutes by car and allows everything. Please fix that and it will be perfect.
