Haginaka Park

A broad sandy beach and open lawn give kids somewhere to dig and run without leaving the city.

The obstacle course is the reason to come, with rope climbs and balance challenges that feel like a mini adventure race.

A neighborhood park with a real playground and plenty of open space, easy to combine with the bigger parks nearby.

A playground, aquarium and summer pool all sit in the same long park, so it is easy to make this as big a day as you want.

A paid playground with lots of climbing and slides, useful when you want something contained and very clearly built for kids.

Free and compact enough for a casual afternoon, with animals tucked into a hilltop park rather than a massive zoo complex.
