An overnight ryokan stay in either Kusatsu or Ikaho, Gunma’s two most celebrated onsen towns, offers a complete traditional hot spring experience that a day trip can’t match — tatami-floored rooms, futon bedding, an elaborate multi-course kaiseki dinner, and typically unlimited access to the ryokan’s baths at any hour, allowing repeated soaks morning, evening and night. Kusatsu offers Japan’s top-ranked spring water and the dramatic Yubatake, while Ikaho’s distinctive rust-orange ‘golden’ waters and atmospheric stone-step main street offer a quieter, equally traditional alternative.
