The Niseko Mt. Moiwa hot spring is the source of the thermo-mineral waters at One Niseko’s Onsen. The therapeutic water contains naturally-occurring sodium hydro-carbonate, and many people consider it a source of healing. Whatever the case, at the end of the day it’s a singular pleasure to sooth away your aches, pains, and stress as you sit up to your neck in the hot natural water – indoors or outdoors.
The changing rooms have been designed by Kengo Kuma – who also designed the symbolic entrance façade of the hotel – in a way where tradition and the contemporary blend stylishly.
