161. Yoshinoike Onsen, Yamanashi A civilized, grandmother-run onsen. As I understood, they even have courses that include meals. Onsen was 750 + 270 for a towel. The building is a bit out of the way and looks like a residential house, but it's a quick walk from the nearest train station. They stamp the Yamanashi 100 Onsens booklet. Couldn't find a water composition chart. Inside there's one small bath. Breathing inside is comfortable, the atmosphere is pleasant too. Water is clear with fine mineral deposits, noticeable chlorine smell. Temperature hot-. There's one shower, and instead of body wash and shampoo - bar soap. Worth stopping by if you're nearby or passing through, otherwise can be skipped.
