A new lodge-style sauna (pictured) opened at Hakuba Oak Village in January 2026. The “Patio L Plus” sauna cabin, introduced to Japan for the first time, is a private sauna featuring a fully equipped sauna room with an authentic Harvia stove (capacity: up to 5 people) and a changing room. Each session is 120 minutes per group, and after your sauna, you can enjoy the large, natural hot spring bath at Hotel Oak Forest free of charge (from JPY2,500 per person, bath towel included, *large public bath available from 13:00 to 21:00).
