Yoshinoya Kawaguchiko Fujisan draws bicarbonate-rich geothermal water in the Fuji Five Lakes region, where thermal bathing with perfect cone-shaped views of Mount Fuji reflected in the surface of Lake Kawaguchi creates the quintessential Japanese wellness postcard — an experience that has drawn Japanese and foreign visitors to this volcanic highland since the establishment of the Fuji worship tradition in the Edo period. The bicarbonate spring waters emerging from volcanic geology in the Fuji volcanic zone provide therapeutic mineral bathing for digestive and circulatory conditions in a resort region that was designated UNESCO World Heritage property in 2013 for Mount Fuji's extraordinary cultural significance as Japan's sacred mountain and the subject of more artistic representations than any other natural feature in the world. The autumn red foliage of Fuji's lower slopes, the morning calm on Lake Kawaguchi when Fuji's reflection is perfect and undistorted, and the local hōtō flat noodle hotpot cuisine of the Yamanashi highlands create a complete sensory Fuji region experience.
