Sumikawa Onsen

Sumikawa Onsen is a Japanese thermal spring set along a river valley where the name—Charcoal River or Corner River—evokes the deep, shadowed tones of a forest-shaded watercourse far from urban light, a landscape of particular Japanese beauty in its quiet, unornamented naturalness. The spring offers the intimate character of a rural Japanese onsen where the bathing experience is shaped entirely by natural surroundings—the sound of flowing water, the scent of minerals rising from the spring, and the seasonal changes in the surrounding vegetation that mark the passage of the year. Visitors seeking the simplest expression of Japan's thermal bathing tradition find in Sumikawa a spring defined by its natural setting above all else.
