800. Naraya, Kusatsu Onsen, Gunma ★ I went for a higaeri for ¥1,500, they give you a small towel. Higaeri is listed from 12:30 to 14:00. 1. An indoor oval bath in a spacious room. The water is clear turquoise. It has that proper sulfurous onsen smell. The temperature was 42.5. The air inside was easy to breathe, and it was cool in winter. 2. An outdoor bath, balcony style. There is no view, everything is closed off. The water is clear turquoise, with fine lime deposits. The temperature was 42.5. A pleasant place, left a good impression. 14.01.2026
