A sodium-led bicarbonate spring with a salt-tinged finish from a chloride sub-type, classified as a cold-mineral spring drawn at 22.7 °C and heated for bathing. Neutral in pH and soft on the skin, it carries metasilicic and metaboric acid alongside dissolved gas that bubbles up at the wellhead. With around 2,500 mg/kg of dissolved solids it is moderately mineralized, giving the water noticeable body.

337. Tsuki-no-yufune, Kobe ★ A super sento with onsen water for ¥960, about 40 to 60 minutes from Kobe Station. Judging by the text on the official site, they may mix the water: they pump onsen water from 1000 meters underground and also use seawater. Hours are listed as 09:00 to 24:00. They stamp the Kansai 24/25 Super Sento stamp rally. There is a diner, massage, hair salon, a Dyson dryer for ¥100, Kobe merch, a shop, massage chairs, a chill-out area, and arcade games. The bath photos are from the internet, and they match. 1. Outdoor area. There is a simple view through the fence of the forest, the city, and the bridge. 1.1. Square bath, the water is clear and only slightly cloudy, with a light, proper onsen sulfur smell. Temperature 40. From the photos on the internet and on the site, it may look like an infinity bath, but no matter how hard I tried, I could not get an infinity view, so I note that it does not have an infinity view. 1.2. Stone bath, the water is clear and only slightly cloudy, with a light, proper onsen sulfur smell. Temperature 39-40. 1.3. Area for lying in the water. 2. Indoor area. It is tolerable to breathe, with a light chlorine smell. 2.1. Main bath, the water is clear, temperature 40-41. 2.2. Jet set, sitting/standing. 2.3. Jet set, lying down. 2.4. Sauna. 2.5. Cold bath. The building itself feels cozy, and the onsen is also fairly even. There are small touches like a Dyson dryer and Kobe merch. It is worth considering if you are nearby or passing through. 05.01.2025
