Kusatsu Onsen in Winter: Road Closures, Snow Driving and Getting Around
Plan winter access to Kusatsu: the Shiga-Kusatsu Kogen Route closes seasonally, and the town itself needs snow tyres or chains on icy roads.
One road-closure headline can sound as if Kusatsu Onsen has been cut off. Often it refers to the high-altitude route across the mountains toward Shiga Kogen, not the roads into the hot-spring town. Check the named section before changing plans.
Reaching the town is different from crossing the mountain pass
Kusatsu’s central hot-spring area is around 1,200 metres above sea level. The association says winter visitors driving into the area need snow measures such as studless tyres or chains. If you are renting a car, confirm the equipment with the rental company before setting off; do not decide at the foot of the mountain based only on how the weather looks in the city.
The Shiga-Kusatsu Kogen Route, National Route 292, normally closes for winter from around mid-November until late April. Volcanic activity can bring additional restrictions outside that seasonal closure. Those restrictions concern the high route and can change by section; they do not automatically mean the Yubatake area is inaccessible.
As of September 27, 2026, the association’s road page showed a July 29 status update. That is not a same-day guarantee for a later trip. Check the live page and Gunma’s road notices before driving toward the pass, and check the separate access routes into Kusatsu if your destination is the town itself.
Driving: give the mountain road more time than your map suggests
Snow, ice, visibility and traffic controls can change the pace even when the main approach remains open. Plan to arrive with daylight to spare, and avoid stacking another distant stop immediately before a winter check-in. Once parked, walk around the central area rather than repeatedly moving the car through snowy streets to save a few minutes.
Road access and parking are different questions. The association has separate road and parking cameras, including views of Route 292 approaches and several car parks. They can help show current conditions, but a camera feed may be unavailable and cannot replace official closure information.
Without a car: check the transfer, then the last walk
The two rail gateways are JR Naganohara-Kusatsuguchi and Shinkansen-served Karuizawa; both require a bus onward to Kusatsu. Direct highway buses also run from the Tokyo area. Bus times and routes vary by operator and date, so recheck both legs before departure. The no-car Kusatsu route guide explains the trade-offs between them.
At Kusatsu Onsen Bus Terminal, Yubatake is about a five-minute walk. That distance can feel very different on wet snow or ice, particularly with a rolling suitcase. Use grippy footwear and ask your accommodation about pickup or luggage storage if it is outside the central walking area. A bus delay can also affect check-in and dinner; tell the inn your expected arrival time.
Keep the sightseeing loop small
In winter, plan the town around a short central loop rather than trying to tick off every bath and viewpoint. Yubatake and nearby streets make an easy first outing. Add the longer walk toward Sainokawara Park only if the surface and visibility are comfortable; allow for the return walk, changing and the route back to your hotel.
An overnight stay takes some pressure off the same-day climb in and out. If you are weighing that against a day trip, the Kusatsu day-trip versus overnight guide lays out what the extra evening and morning actually give you.
