Otsuki Onsen occupies a strategic gateway city where the Chuo Line and Chuo Expressway converge as they pass between Tokyo and the Fuji Five Lakes region, making Otsuki a natural resting point for generations of travelers entering or leaving the Fuji highlands. The city's most celebrated attraction is Saruhashi Bridge, one of Japan's three great ancient stone bridges, an arching structure spanning the Katsura River gorge that appears in countless Edo-period woodblock prints and landscape paintings celebrating the beauty of the Kanto mountains. Mineral waters from the onsen provide a warm and welcome pause at this crossroads between the megalopolis and the mountain world that has defined Otsuki's character for centuries.
