Classification

Sodium Bicarbonate spring

A hot (61 °C) sodium bicarbonate spring — the classic jūsō-sen style, soft on the skin. Alkaline at pH 8.5, it sits comfortably in Japan's beauty-water family. A generous 256 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards. The brown clear water is the signature look of a plant-derived moor spring.

371. Tsurumaru Onsen, Tsurumaru, Kagoshima Visited for higaeri for 300 yen — an old-school place. Higaeri listed as 06:00 to 20:30. They stamp the 88 Onsen of Kyushu book. Inside: two baths. Clear dark brown water, one bath at temperature around 41.5, the second at 47. Breathing is comfortable. A small door in the corner turned out to be not an emergency exit but a door to the outdoor zone with a square rotenburo — unfortunately I found this out after my visit. So if you go without preparation, check all doors in the indoor baths. Atmospheric place with an extremely hot bath. Next time I'm in the area, I'll come back to check out the old-school rotenburo.
