A sodium bicarbonate spring of the classic jūsō-sen style, weakly alkaline and soft on the skin. The on-site notice describes the water as smoothing and silky underfoot — squarely in Japan's beauty-water family. The source emerges lukewarm at 35.4 °C so the bath is reheated for comfort, but otherwise it runs as a free-flowing, undiluted source with no recirculation or disinfection.
