Enjoy 18 types of private open-air hot spring baths with 100% free-flowing natural spring water.

If you love Onsen, this place is truly heaven—there are 18 private baths. This was my third stay, and I still haven’t managed to try them all. The detached cottage “Aoi” has its own open-air bath, which is absolutely wonderful. I always end up completely satisfied just using the bath in the Room. The spring quality is a simple Onsen (slightly alkaline, hypotonic, high-temperature) with a pH of 8.3. It feels gentle on the skin and is easy to enjoy in a different way from more distinctive springs like sulfur Onsen. It’s comfortable for longer soaks, and being able to enjoy it many times during your stay is part of the appeal. Many of the open-air baths have a rustic, DIY-like feel. Numerous private baths are scattered across the vast grounds, and I can only imagine how much work it must be to maintain and manage so many. Because this Accommodation is surrounded by nature, things like insects and fallen leaves are somewhat unavoidable. In July there were quite a few insects, and when I visited last September I also had trouble with biting gnats. Even so, this Accommodation has more than enough charm to make up for it. The source spring has an abundant flow rate, and the source temperature is very high at 76.1°C. To bring it down to a comfortable temperature, adding water may sometimes be necessary. As an Onsen lover, I’d ideally like to enjoy pure free-flowing water without dilution—but with such a high-temperature source spring, I understand that temperature control can be challenging. Many of the staff are from overseas, but everyone speaks Japanese well and I’ve never felt inconvenienced. They are always polite and attentive. And despite being such a secluded hot-spring retreat, it’s great that the meals are genuinely delicious as well. This time we ordered sukiyaki as an extra dish; it was excellent and very satisfying. In winter this area apparently gets extremely heavy snowfall. Next time I’d love to visit in winter and enjoy an outdoor bath while admiring snowy scenery.

Enjoy Kusatsu with your family! A soothing Onsen resort surrounded by lush forests

We stayed for one night and two days with our grandchild. As mentioned in other reviews, the building and rooms are indeed a bit old, but everything was properly cleaned and we had no issues. With the all-you-can-play passport, we enjoyed bowling, the pool, craft-making, festival-style games, quizzes, a stamp rally, and more—plenty to keep us entertained. The free shuttle bus from the hotel to Yubatake at night was extremely helpful; it was my first time seeing the Yubatake illuminations, and I was surprised by how many tourists were there. Even though it was summer, walking around Yubatake felt pleasantly cool—almost a little chilly—which was wonderful. The next day we used the hotel shuttle again because I wanted my grandchild to enjoy street food and try the yumomi experience as well. We had only ever visited Kusatsu in winter before, so this was our first summer visit. While news reports talked about extreme heat in Tokyo, we were amazed at how cool and comfortable Kusatsu was in summer. At night we didn’t need air conditioning in our room—it actually felt slightly chilly. Summer in Kusatsu is great. The food was delicious, and everyone at the front desk, reception counters, and shop—especially the international staff—was very polite and pleasant. Every staff member provided excellent service; I was truly impressed. This hotel is highly recommended for families with children as well. We would love to visit again. The only downside is that the hotel is so large that it’s easy to get lost—especially when trying to find the baths (as other reviews mentioned), and yes, we got lost too. Overall though it was a wonderful hotel. Thank you very much.
