My stay at Kusatsu Onsen Boun was good, with cozy accommodations and a beautiful atmosphere. but communication was a slight challenge since only one staff member spoke minimal English. The meals were a highlight, and the onsen experience was beautifully relaxing, though the maximum capacity limits meant a bit of crowding at times.
