Hoshino Resorts Tomamu Spa is located within the Hoshino Resorts Tomamu complex in Shimukappu village in the Sorachi Subprefecture of central Hokkaido, a world-class mountain resort famous above all for its extraordinary 'sea of clouds' phenomenon — the Unkai Terrace observation deck above the resort regularly witnesses the valleys below filling with dense low cloud at dawn, creating the magical appearance of a vast white ocean stretching to the horizon from which mountain peaks emerge like islands, a sight that has made Tomamu one of Japan's most photographed natural phenomena. The resort's winter season draws international visitors with some of Hokkaido's finest powder snow conditions, combining champagne powder skiing with the resort's distinctive onsen and indoor beach pool facilities. The spa draws on Shimukappu's volcanic geothermal resources, delivering silica-rich mineral bathing in a purpose-built resort environment that offers every comfort while maintaining a genuine connection to the extraordinary mountain landscape surrounding the complex.
