The Ultimate Onsen
and Wellness Centre
Overlooking the ski slopes of Mount Annupuri and spread over 620sqm, the Spa and Wellness Centre at Setsu Niseko is set to be one of the largest wellness facilities within Grand Hirafu.
Embracing Japan’s centuries-old onsen tradition, Setsu Niseko will enjoy mineral rich hot volcanic spring water direct from its own private spring source 800 metres underground. Perfect for star gazing, this serene oasis is designed around two large open-air onsens which use the ‘Kakenagashi’ cycle of natural filtration, where the mineral rich water flows through the onsen bath and back into the ground. It is then naturally filtered by stoney subsoils on its way back to the natural reservoir that feeds the onsen.
For those seeking a more private experience, Setsu Niseko’s private onsen rooms complete with their own separate changing rooms, storage facilities and tranquil lounge provide the ultimate exclusivity. Setsu Niseko’s Spa also features two large indoor onsens, a cold dipping pool, sauna facilities, changing rooms with locker facilities, a private lounge area and a fitness centre. For those looking to indulge in a little more ‘me’ time, a series of spa treatment suites offering a range of massage and beauty treatments complete Setsu’s pampering experience.
