534. 南アルプス市営温泉 樹園, Minami-Alps, Yamanashi Onsen for 750 (450 for locals). The vibe is like an old-school sanatorium for medical treatments. Operating hours are listed as 10:00 to 21:00 (closed Thu). They stamp the Yamanashi 100 Onsen book. Bath photos are from the internet, partially match — couldn't find proper photos online. Indoor area. Breathing inside is tolerable. Pixelated photo wallpapers of cherry blossoms and a beach town with high-rises hang on the walls. 1. Bath with clear slightly yellowish water, temperature around 41. 2. Open zone behind doors leading outside with two weird showers and two chairs. 3. Bath with clear slightly yellowish water, temperature around 39. 4. Bath with clear slightly yellowish water, temperature around 35-37. 11.05.2025
