Opening July 2026 | A Kusatsu Accommodation with an Open-Air Bath, Sauna, and Dog Run
In addition to sightseeing in Kusatsu Onsen, you can also relax at the Hotel with a large public bath, sauna, and after-bath lounge. We offer dog-friendly rooms, a dog run, and free rental pet supplies. You can also enjoy a wide selection of free rentals such as Nintendo Switch consoles, board games, ski gear, baby items, and beauty appliances (available on a first-come, first-served basis; quantities are limited). About a 15-minute walk to Yubatake. Free parking for 67 cars is available in front of the Hotel (first-come, first-served; no Reservation). About 25 minutes by bus from JR Naganohara-Kusatsuguchi Station and about a 10-minute walk from Kusatsu Onsen Bus Terminal.
We stayed with our dog during the pre-opening period.There are various rules for using the Accommodation, but they were not clearly explained on the Reservation site or elsewhere, so there was very little information in advance. Until we arrived at the Hotel, I was quite worried. On-site, however, there were written instructions at key points, so we did not have many problems.That said, I think things would go much more smoothly if guests could understand everything beforehand rather than having to figure it out each time.I appreciate that simplifying services helps lower prices, but if guests are expected to handle many things themselves, the system needs to be communicated in detail in a way that anyone can easily understand.- Our dog’s vaccination certificate was not checked. For guests traveling with dogs to feel comfortable and use the Accommodation with peace of mind, I believe this should be mandatory and consistently enforced. Also, there was no explanation at all about how to use the dog-friendly Room; some basic rules and guidance seem necessary.- As mentioned in other Reviews on other sites as well, there was no sanitary disposal box in the restroom. I think this is something that should be provided.- Free rental items are available on a first-come basis. The notice said: “After use, keep it clean and finally clean it and return it to its original place.” This made me wonder whether the Hotel checks (cleans/maintains) these items properly every day after they are returned. If not, it would feel unhygienic.- The notes on the Reservation site stated: “A deposit (20,000 yen for all Rooms) will be collected.” However, when I asked staff in the lobby on the day of arrival, they told me no deposit is collected.- I appreciated having a 2-liter bottle of water provided in our Room.- All staff who assisted us inside the Hotel (lobby and breakfast venue) were pleasant, polite, and clear.With this rebranding renovation, the facilities are already very appealing as a Hotel. I hope that service operations will improve accordingly and become even better than they are now.
