Kusatsu, Ikaho and Shima are three of Gunma’s best-known onsen towns, but they offer very different trips. Kusatsu is lively and iconic, Ikaho centres on its historic stone steps, and Shima is a quieter river-valley retreat built around ryokan stays.
The quickest way to choose
Choose Kusatsu for the strongest first-time onsen-town experience, Yubatake, steam and a lively evening atmosphere.
Choose Ikaho for the Ishidan-gai Stone Steps, old-town photographs and comparatively easy access from Tokyo.
Choose Shima for a quiet riverside stay where the ryokan, baths and scenery matter more than nightlife or a long attraction list.

Kusatsu Onsen
Kusatsu has the most immediately recognisable onsen-town scenery. Yubatake sits at the centre, surrounded by steam, shops, public footbaths and illuminated streets after dark. The traditional yumomi performance adds another distinctly Kusatsu experience.
Its popularity also means more crowds and higher prices on busy dates. A hotel beside Yubatake is convenient for evening walks, but travellers who value quiet bathing may prefer a ryokan slightly away from the centre or one with private-bath options.
Ikaho Onsen
Ikaho is built around the Ishidan-gai Stone Steps, lined with ryokan, cafés, souvenir shops and small attractions. It suits visitors who enjoy walking through an old-town streetscape as much as soaking in the baths.
The slope matters when choosing accommodation. A hotel described as “near the Stone Steps” may still sit above or below your preferred section, and luggage can be awkward on steep paths. Check the entrance elevation, shuttle service and distance from the bus stop rather than relying only on a map pin.
Shima Onsen
Shima Onsen is quieter and more spread out along a river valley. Its appeal lies in the ryokan experience, forest scenery and slower pace rather than a dense shopping street. Historic Sekizenkan is the best-known landmark, but the town works best when you choose accommodation you are happy to spend time in.
Visitors looking for nightlife, frequent cafés or a long list of attractions may find Shima too subdued. Those wanting a peaceful night, riverside walks and repeated baths often find it the most restorative of the three.
Transport from Tokyo
Ikaho is generally the simplest to combine with Takasaki and Shibukawa, making it practical for a short one-night trip.
Kusatsu takes longer but has mature train-and-bus connections and extensive visitor facilities once you arrive.
Shima usually requires careful coordination through Nakanojo, especially for the final bus and your ryokan’s shuttle or check-in time.
Compare the full journey, not only the fastest train. Transfers, the final bus, luggage and hotel pick-up often matter more than a small difference in headline travel time.
Autumn and winter
All three are attractive from autumn into winter. Late October and November can bring foliage, while winter gives the strongest contrast between cold air and hot water.
Kusatsu sits at a higher elevation and can be considerably colder, with snow and icy streets. Ikaho’s stone steps become slippery, and Shima’s valley roads may also be affected by winter conditions. Bring footwear with grip and check bus disruption notices rather than dressing according to Tokyo temperatures.
How to plan one night
Arrive in the afternoon and leave luggage at the ryokan.
Walk through the main town area before dinner.
Keep the evening for the ryokan meal and baths.
Add one or two nearby stops the next morning before returning to Tokyo.
Do not try to visit two onsen towns in one day. The extra buses and luggage handling consume the time that makes an onsen trip worthwhile.
Accommodation trade-offs
Kusatsu has the widest range of hotels but the sharpest price increases on popular dates. Ikaho offers options across more price levels, though location on the slope needs careful checking. Many Shima properties are designed around a complete ryokan stay, so compare meal plans, private baths, shuttle service and river views—not only the room price.
Which one is right for you?
First onsen trip and want the most iconic memory: Kusatsu.
Couple’s trip with old streets and easier transport: Ikaho.
Quiet solo trip or ryokan-focused escape: Shima.
Travelling with older relatives: check Ikaho’s stairs, Kusatsu’s winter ice and the distance between Shima’s bus stop and your ryokan.
