Fuji Kawaguchiko Onsen

Fuji Kawaguchiko Onsen—also simply called Kawaguchiko Onsen—rises on the shore of Lake Kawaguchiko in Yamanashi Prefecture, where bicarbonate and naturally carbonated mineral waters are enjoyed with what may be Japan's most iconic backdrop: the reflected perfect cone of Mt. Fuji in the still waters of one of the Fuji Five Lakes, creating a thermal bathing experience of surpassing visual magnificence. The effervescent CO2 and bicarbonate mineral content of the spring waters add a lively, refreshing quality to the soak, while the lake shore setting places the bather at the very edge of Japan's most symbolically significant volcanic mountain's reflection pool in a composition of volcanic geology and thermal tradition. Soaking in these sparkling mineral waters while contemplating Fuji's cone represents one of the most complete expressions of the unity between volcanic mountain, thermal spring, and Japanese aesthetic tradition.
