68. Sachinoyu, Gero Onsen One of the three public onsens in Gero. Operating hours are listed differently in different places (one says 12 to 22 except Tuesdays, another says 14 to 21 except Mon-Tue). Tegata is not accepted here. Style-wise it's a sento with onsen water — you even need to bring your own shampoo. Prices in photo. The establishment has the following baths: 1. Main round bath. 2. Round jacuzzi bath. 3. A nice utaseyu (waterfall bath). 4. Cold water bath. 5. Outdoor square bath. Water in the baths is hot, clear. Breathing inside is fine. Overall there's probably little reason to go to this onsen in Gero, unless you're specifically craving a sento atmosphere.
