Top Annaka Hotel Reviews

Kusatsu Onsen Hotel Sakurai

10/10 Excellent

"There are two onsen baths; one inside and one outside. The water in the open bath makes your silk feel silky and smooth. The buffet breakfast and dinner are of good quality with many varieties. The night shows are good entertainment at the hotel. We had a relaxing stay at the hotel."
