Make time for an onsen.
Kotobuki no Yu is on the Resort Hotel’s North Wing sixth floor. Leave time for the outdoor outlook and indoor baths after your ski day.
Paid day visits are arranged at the front desk. Hotel guests should check their package conditions; this is distinct from the Westin’s own onsen.
