The onsen is a great way for everybody to relax and unwind. The mineralised waters have been said to be effective in aiding the treatment of skin issues, tight and sore muscles, inflexibility as well as other health problems. The best feature though is their warmth – nothing beats an evening dip after a long day in the snow. The Westin is home to a stunning onsen, featuring both an indoor and outdoor pool which looks out across the landscapes, as well as a sauna. The South Wing also offer a great bath house for you to enjoy with friends and family after a day on the slopes.
