About Gensen Ichinoyu Onsen Ryokan
You'll find Gensen Ichinoyu Onsen Ryokan (源泉一乃湯) in Kusatsu, in the Kusatsu area. Here is what the property's own website tells you about bathing in private, translated and checked, with a link to each source.
The official site advertises rooms with a private open-air bath. Treat these as specific room types rather than the standard room, and choose that plan when you compare prices. There are private (kashikiri) baths that one group at a time can lock and use, and the website lists a charge (¥3,200). The website doesn't explain how slots work, so ask at check-in.
The property describes its water as free-flowing (源泉かけ流し), fed from the source rather than recirculated. The website doesn't state a tattoo policy. If that matters to you, email the property before booking.
Anything marked 'not confirmed' below, such as tattoo rules for private baths, wasn't stated on the pages we checked. That doesn't mean the answer is no, only that we haven't assumed one. We checked the official website on 17 October 2026. Rules and fees change, so confirm with the property, and use the buttons above to compare the same room across booking sites, including taxes and cancellation terms.
