Culinary Excellence
Dining & Bar
Hokkaido's four distinct seasons are deeply connected to the concept of 旬 (shun) — the appreciation of ingredients at their natural peak. From Shiokaze Restaurant's refined Japanese cuisine to the Raiden Bar's signature cocktails with sweeping coastal views, each experience reflects the rhythm of the seasons.
Wellness & Leisure
Spa & Wellness
Overlooking snow capped mountains, natural seawater hot spring baths are complemented by traditional Japanese oil and stone treatments, a pressurized oxygen capsule, and a complete wellness journey rooted in Japanese tradition.
Adventures & Culture
Experiences
Skip the lift lines and chase untouched powder through expansive alpine bowls and old growth glades. On a typical day, you'll ski up to 5,000 vertical meters of pristine descents; there's no better way to experience Hokkaido's legendary snow.
