Ki Niseko was deemed to be home to Niseko's best onsen, in a top 10 list published by the team at Mountainwatch late last week. Their setup includes male and female public onsens, each with inside baths and outdoor stone rotenburo baths. There are also two family onsens that can be booked in advance for those after a little more privacy, as well as saunas and plunge pools for the complete rejuvenating experience.
Best of all, the mineral-rich water comes from Ki Niseko's own exclusive source and is guaranteed to help sore muscles recover after a hard day of skiing. The catch - only hotel guests are allowed to use the facility, which means you'll have to book your stay to experience Niseko's best.
The list also featured lower Hirafu's Onsen Yukoro, a favourite for travelers who like to take in the age-old Japanese cultural experience with a cold beer in hand.
