A rare carbonated spring that earns its name — fine bubbles cling to the skin the moment you enter. The wellhead is a cool 31.5 °C and free CO2 reaches 1,400 mg/kg, so bathers stay in long while the carbonation tingles. The base chemistry is a magnesium-sodium bicarbonate water, neutral pH and lightly mineralized, with a generous 172 mg/kg of metasilicic acid adding softness to the skin feel.

425. Lamune Onsen, Taketa, Oita (Nagayu Onsen) Onsen for 500. Private bath available for 2,000 (didn't take it). Operating hours stated as 10:00 to 22:00. They stamp the 88 Onsen of Kyushu book. Bath photos from the internet match reality. Inside there's a three-level bath. Cloudy white-pale-green water, temperature 38-39. Breathing inside is excellent. When I got in, two old men were sleeping in the baths. After sitting down, within 3-4 minutes I started getting extremely drowsy and nearly face-planted into the water. I don't know if it was a coincidence or if there's really some combination of factors that's this relaxing at this onsen. Outdoor bath with clear carbonated water, cool temperature. An unusual place in terms of decor, the wildlife inside, and the baths themselves. If you're in the area or rushing the 88 Onsen of Kyushu achievement, recommended to stop by.
