Classification

Sodium Chloride spring

A hot (58.3 °C) sodium chloride spring, weakly alkaline and soft on the skin. Moderately mineralized at 2,191 mg/kg dissolved solids, it carries the salty, heat-retaining body of a Na-Cl water with a bicarbonate softness layered in. The standout is its metasilicic acid content — a generous 202 mg/kg leaves the kind of silica film that places this firmly in Japan's beauty-water family.

374. Funatsu Onsen, Aira, Kagoshima Onsen for 460 yen. Operating hours listed as 09:30 to 22:00. They stamp the 88 Onsen of Kyushu book. Photo of the outdoor bath from the internet matches. 1. Outdoor stone bath, clear water, temperature around 40. The view is blocked by a fence. 2. Indoor zone. 2.1. Main bath with clear water with a round bubble zone, temperature around 41-42. 2.2. Electric bath. 2.3. Sauna. 2.4. Cold bath. A decent place — worth stopping by if nearby, but I wouldn't go out of my way.
