Kusatsu in Winter (and Summer) with Kids

Kusatsu has two very different faces worth planning around: a snowy, festive winter — its headline season — and a cool, quiet summer that most foreign visitors never think to use. Both work well with kids in different ways. This is the seasonal deep-dive behind the main Kusatsu with kids guide.

Winter — the headline season

Kusatsu pairs an onsen town with real snow, which is a lovely combination with children — a steaming Yubatake ringed in white, gentle beginner slopes, and a proper first taste of snow.

Another face of the Yubatake: falling snow

The Yubatake is the town's centrepiece year-round, but winter gives it a second look: steam rising into freezing air, the surrounding stone dusted white, and — lit up after dark — its prettiest against snow, an easy evening stop. On a day of real snowfall it turns quiet and almost monochrome, atmospheric for a short look with the kids well wrapped up.

Winter nature around Kusatsu

Kusatsu sits in real snow country at around 1,100–1,250 m, and the peaks around it — including Mt. Kusatsu-Shirane — stay snow-covered through the season, a dramatic white backdrop to the valley. It's scenery to take in from the town and the slopes, not a winter hike with little ones.

Snow play and skiing with kids

For families, the snow itself is the draw:

• Kusatsu Onsen Ski Resort sits just 5–6 minutes by car from the Yubatake, with a free shuttle from the bus terminal, and a good share of beginner runs — a genuinely family-friendly hill rather than an experts-only one.
• The kids' snow park has things like a snow escalator, sledding, and a children's practice slope. This season's opening dates, prices and entry rules change every year, so confirm them on the resort's official page before you build a day around it.
• For little ones, there's paid childcare with qualified staff ("Yukinko House"), plus a nursing room and free rest areas — so a family with a baby and an older child who wants to ski has a base for both.

Summer — the quiet escape

Summer is Kusatsu's underrated season. At about 1,200 m it's a genuine escape from the heat: July and August average around 19–20°C, and it rarely climbs past the mid-20s — noticeably cooler than Tokyo, and a relief for kids who wilt in the city heat.

• Mt. Tengu's green season runs outdoor activities such as the BanZip TENGU zip line and a sky swing. These have age, height or weight limits and seasonal hours and prices, so check the official site — the zip line in particular suits older kids, not toddlers.
• Summer festivals are a highlight: the Shirane Shrine festival (typically mid-July) and the hot-spring thanksgiving festival (typically early August), both with stalls and a lively evening. Confirm this year's exact dates officially, and note festivals can bring evening road closures.
• River play and outdoor pools: options are limited and the details aren't reliably published, so treat the riverside as a hot-spring experience rather than a swimming spot, and check directly with venues or the tourism association.

Which season for your family

• A first taste of snow — toddlers in a snow park, older kids on beginner runs — makes winter the obvious pick, just packed for the cold.
• Escaping the summer heat, slow days, and cool nights for better toddler sleep point to summer, the season few foreign families consider.
