SANSUI is a private villa retreat in Akan–Mashu National Park, eastern Hokkaido. Surrounded by lakes and forests, it offers refined comfort and a deep connection with nature. The property features two villas, each with exclusive facilities and complete privacy. Villa NUKUMORI has two bedrooms, a private open-air hot spring bath, and a wood-fired sauna, ideal for relaxation and wellness. Villa MIGIWA, located just steps from the lake, offers three open-air baths with panoramic views, where guests can enjoy the changing colors of the water from morning to night. Both villas provide spacious living areas, modern amenities, and interiors blending natural materials with contemporary design. They are suited for couples, families, or small groups seeking a serene escape. At SANSUI, every stay is an experience—soaking in mineral-rich hot springs, feeling the forest breeze after a sauna, or stargazing under clear skies. Optional meal sets with selected Hokkaido ingredients are also available. Easily accessible from Kushiro or Memanbetsu airports, SANSUI invites you to slow down, reconnect with nature, and create lasting memories.
