What: Small spa with an amazing indoor-outdoor onsen in red-hot Niseko, Japan's answer to Aspen. (Niseko did not sustain any damage in the March earthquake.)
The look: Tucked behind frosted glass, the Alexandra Champalimaud-designed space mixes beautiful murals by artist Emi Shiratori. Treatment rooms have large mattresses on the floor behind curtains.
Who goes: Trendy après-ski Tokyo types and clued-in powder-loving expats (Niseko has the best snow in Asia).
The treatment: The 45-, 60-, or 90-minute Off Piste works out ski-weary muscles. Beware: The tiny technicians have the pressure of sumo wrestlers.
P.S.: Make sure you follow onsen etiquettethere are different sections for men and women.
