Masunari-ya Ryokan. Probably the first ryokan in Kusatsu that I liked enough to stay again. Rooms are large, very nice-looking, a bit dated, but the ryokan itself isn't new either. Really liked the bath system - besides the main bath, each room (6 total) gets a key to its own kashikiri, with water from two sources: Yubatake and Shirohata (whichever you're lucky to get). Excellent food, very tasty.
