A hot (43.9 °C) sodium bicarbonate-chloride spring — the soft, skin-smoothing 'jūsō-sen' style with a salty chloride finish layered in. Neutral pH and a moderate 2,356 mg/kg of dissolved solids give it body without heaviness, and 65 mg/kg of metasilicic acid sits firmly in beauty-water territory, leaving skin noticeably smoother after a soak.

386. Tatsugashira Onsen, Kikuchi, Kumamoto Old-school onsen for 350 yen. Operating hours listed as 06:00 to 22:00. They stamp the 88 Onsen of Kyushu book. You need to bring your own soap/shampoo or buy it. Photos from the internet match. Inside: two baths. Clear, carbonated water (naturally carbonated as I understood). One bath at temperature around 42, the second at 40. Breathing is fine. Outside: stone bath with clear water, temperature around 40. Separate stone cold bath.
