A Rainy Day in Kusatsu with Kids: Indoor Stops That Actually Work

A wet day in a mountain town needs a plan — the Yubatake is less fun in the rain, and a cold, soggy toddler is no one's idea of a fun trip. The good news: Kusatsu has enough indoor stops to fill a half-day without leaving the town center. This is the detailed version of the hub's rainy-day notes; for the wider picture, start with the main Kusatsu with kids guide.

The reliable indoor stops

Three places do the heavy lifting on a rainy day:

• Kusatsu Tropical Zoo — an indoor, spring-heated animal dome where it's warm whatever the weather. It's open roughly 8:30–17:00, with adult admission around ¥1,300 at the time of writing; it's also the most stroller-friendly stop in town.
• Manga-do — a bright, open read-all-you-like hall with over 10,000 comics, near the Yubatake. Older kids who can read happily disappear into it; it's a genuine local go-to when the rain sets in.
• Terme Terme — the indoor pool-and-bath complex at Hotel Village, with a swimsuit-pool area as well as bathing. A good way to burn off energy under a roof, though its hours and any seasonal (summer-only outdoor) pool are worth confirming with the venue before you go.

Hands-on and quieter options

If you'd rather do than watch:

• Glass-making at Kusatsu Glass Studio (草津ガラス蔵) — small craft experiences such as making a glass piece. Age limits and what each session involves vary, so check before you build the afternoon around it.
• The Kataoka Tsurutaro Art Museum — a calm, dry hour for families with older kids.
• The town's indoor heated pool — a straightforward option when you just need to let them swim.

Opening hours, prices, and age requirements at all of these change with the season, so confirm the current details on each venue's official page rather than relying on a fixed figure.

Old-school fun near the Yubatake

Tucked into the lanes by the Yubatake are some cheap, cheerful, mostly-covered distractions: shateki (a traditional cork-gun target-shooting stall) and dagashi shops (old-fashioned penny-sweet stores). They cost very little, take a few minutes each, and are perfect for filling the gap between bigger stops when the rain is only spitting. Bring small change — these are cash spots.

If you'll drive a little further — beyond Kusatsu

If the rain has set in for the day and you don't mind a drive, a couple of indoor onsen and a dry lunch sit a short way out — but note these are outside Kusatsu, over in Nakanojo's Kuni hot-spring area (六合), so plan the drive and check the day's opening hours before you set off.

Otoku Onsen is an indoor hot-spring bath in the Kuni area, about 30–40 minutes from Kusatsu by car — a warm, dry alternative when the town baths are busy.

Choei-no-Kakureyu ("Choei's hidden bath") is another indoor bath in the same Kuni area of Nakanojo, a similar 30–40 minute drive from Kusatsu.

Reizan Takeyama roadside station (道の駅けやき), in Nakanojo, has a thatched soba restaurant — an easy, dry lunch to pair with the baths on a wet day. It's further into Nakanojo than the Kuni baths, so check the route and hours before you count on it.

With a baby or toddler

For the under-threes, the Tropical Zoo dome is the easy win on a wet day: step-free, warm, and fine with a stroller. Terme Terme at Hotel Village helps too, and Hotel Village has a nursing room (as does the bus terminal). The arcade and sweet-shop lanes are tighter and busier, so a carrier beats a stroller there.
