If you're looking for one of the most premium hotels in the Hakuba area, this is the one I would choose. The service is incredible and they have a staff that speaks different languages.

The main reason I tagged this one is for the onsen experience which is one of the nicest in the Hakuba area. You can also get a good buffet dinner here and pair that with the hot spring. Visit here any time of the year! The views are great, the atmosphere is luxurious, and the place is elegant. You can also arrange your own private hots spring.

Tip: if you're going for a day trip onsen double check the opening times and staying guests get priority and opening times for visitors are limited hours. Also, the sometimes have a mini cooper hot tub in the warmer months!
