Isobe Onsen’s tourist map area in Annaka is a calm, local hot-spring town. Photograph steaming inns, lantern-lit streets, and river/valley views in the surrounding Gunma hills. Early morning mist can soften rooftops for dreamy compositions. Best light: sunrise to late morning, and dusk when windows glow. Weekday visits are quieter.
