Ureshino Onsen Haitō Co. Spring No. 4-1Operated by · 嬉野温泉配湯株式会社
A sodium-led bicarbonate-chloride spring — the classic 'jūsō-sen' style softened by a faint salt-tinged finish. Weakly alkaline (pH 8.17) and soft on the skin, it sits squarely in the Japanese "beauty-water" family that Ureshino is best known for. The wellhead runs hot at 87.9 °C — among Japan's hottest natural sources — and a generous 161 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards.
