A hot (48.7 °C) sodium chloride spring with notably high mineralization at 11.27 g/kg, falling on the hypertonic side. At the wellhead the water shows a faint yellow tint, a mild salty edge and a whisper of hydrogen sulfide — the cert even notes visible gas escape from this drilled self-flowing source. Weakly alkaline pH and the chloride character together give the bath strong heat retention and the characteristic mineral film on skin afterwards.

261. Kawane Onsen Fureai no Izumi, Kawane ★★ A super sento with onsen water for 820. The opening hours are listed as 09:00 to 19:00, except Tuesday. They stamp the Shizuoka 60 Onsen 24/25 rally. It is included in the electronic stamp rally for Yuru Camp. It is located away from the city area of Shizuoka, to the north, there are no guide signs, and it has a countryside atmosphere, even though the complex itself is large. Inside there is food, massage, a shop, a dining area, and a wide selection of local tea. They said tattoos are allowed, but old photos on Google show bans, so it is better to check. The main feature is that from the outdoor onsen bath you can see the railway tracks, and trains pass by there from time to time, there is even a train timetable posted in the onsen. You can even see Thomas the Tank Engine. The train and bath photos from the internet match some of the baths. 1. Outdoor bath area with a view of the bridge with railway tracks, the river that had dried up at the time of the visit, mountains, and forest. 1.1. The hottest bath, with a red layer of deposits on the stone at the upper level. The water is slightly cloudy but clear, with fine, sparse brown mineral deposits. Water temperature 44. 1.2. Bath on the lower level, the water is slightly cloudy but clear, temperature 42. The water has a strong soapy feel. 1.3. A separate large stone bath under a roof, the water is slightly cloudy but clear, temperature 41. The water has a strong soapy feel. 1.4. Square wooden bath, the water is slightly cloudy but clear, temperature 43. The water has a strong soapy feel. 1.5. Bean-shaped bath. Temperature 41. 2. Indoor bath with slightly cloudy but clear water, temperature 41, with a strong soapy feel. It is comfortable to breathe inside. A very cool place, highly recommended to visit. 11.11.2024
