Riverside Warming Kiku Spring

Shidotaira Onsen, one of the Hanamaki hot spring villages, has long served as a bathing retreat along the clear Toyosawa River. Kiku-no-yu is pumped from a drilled well, delivering 72.7°C water at a vigorous 368 liters per minute. Combining the gentleness of sulfate with the lasting warmth of chloride, it carries a faint hint of hydrogen sulfide and fine bubbles. Its warmth lingers long after bathing—a companion for those who want to soak slowly to the sound of the river.
