About Hotel Boun
You'll find Hotel Boun (ホテル望雲) 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. We couldn't find any mention of a separate private (kashikiri) bath on the official site.
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 private baths, the water source and 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.
