Gunma Kodomo-no-kuni Park
SaveA hillside park where a zip line and a summer bobsleigh run down the slope.
Toddlers get a play area of their own, and the children's hall is where you go when it rains.
MoreWhat kind of place
The park's official name is Gunma Prefectural Kanayama Comprehensive Park, and it runs up a hillside in Ota City.
The free play zone is spread across that slope: an adventure fort, a long zip line, a climbing net and a rope-climbing tower. Parking is free and holds about 600 cars, though the lot fills on spring and fall weekends.
There is no souvenir shop, and the snack kiosk beside the service center, TOKOTOKO, opens only on weekends; the rest house serves udon, soba, curry and ramen until a 3:00 p.m. last order.

With kidsThe part that matters
If your children are at different stages, this hillside park gives the smallest ones a play area of their own.
On the same slope a bigger child can ride the long zip line down, and none of that play equipment costs anything.
If it rains you can move the day indoors to the Children's Hall, which has one of the park's two nursing rooms on its third floor.
You can bring your own food and drinks, and though no kettle or microwave is set out, the service center will heat things for you if you ask.
All the paid rides run on weekends and holidays, but on weekdays only the bike-ride area (Cycle Plaza) opens, so pick a Saturday or Sunday if you want the summer bobsleigh and the panorama chair.

Officially this is Gunma Prefectural Kanayama Park. The play zone has the Adventure Fort, a long zip line and an air-filled bouncing dome. Younger children get a separate area with spring toys and a toddler-sized play structure. The cycle plaza runs a monorail bike, a pedal train and battery cars. A summer bobsleigh and a chairlift work between the hilltop and base stations. The paddling pond opens in summer, and acorns turn up under the oaks in season.
