We had a great time enjoying the last days of summer vacation!
We stayed at the very end of summer vacation, and everything was wonderful—the meals, the baths, the renovated Room, and the excellent service from all staff.During meals, we often saw how thoughtfully they looked out for our young children, and the front desk staff were also very kind, making our stay truly pleasant.We had almost given up on using the pool because of the rain, but it cleared up on checkout day, so we were able to fully enjoy both the pool and the slide—our kids were thrilled. Thank you as well to the staff member watching over the pool for regularly skimming leaves and sharing helpful information.It was a perfect way to end summer vacation, and our whole family is very satisfied with these great memories. We will definitely visit again. Thank you for a wonderful time!

Very satisfied.
The Facility is old, but the atelier room was very clean, and the mountain view looked like a painting. The buffet was delicious and very satisfying. The eel rice bowl was so good that I had two servings. There were candied sweet potatoes as well, and all of the desserts were excellent. The Onsen was also great—the open-air bath had a beautiful mountain view and left me feeling refreshed. Thank you very much.
