Heiwa-no-Mori Park Field Athletics
平和の森公園フィールドアスレチック
Heiwajima (Ota), Tokyo · near Heiwajima (Keikyu Main Line) (10 min walk)
A cheap, cheerful municipal obstacle course in Ota City with around 40 challenges — climbing, balance and water obstacles — that most visiting families never hear about. It’s the antidote to a museum-heavy trip: kids run, climb and (sometimes) fall in.
Why children love it: Roughly 40 obstacles including ones over water — it’s a genuine adventure playground, not a tidy park.
What children actually do: Tackle a ~40-obstacle field-athletics course of climbing, balancing and water challenges; younger siblings have a separate, smaller area.
Honest drawbacks: The main course is for elementary age and up, it’s weather- and mud-dependent (closed in rain), and you’ll want a full change of clothes.
How comfortable will an English-speaking family be?
A self-directed outdoor obstacle course needs almost no language; the official information is Japanese-only, but doing the course requires little English.

Why this is under the radar
A municipal Ota-City facility with Japanese-only official information — almost absent from English family-travel coverage despite being a substantial, cheap adventure course.
Getting there: 2-1 Heiwa-no-Mori-Koen, Ota — about a 10-minute walk from Heiwajima Station.
Accessibility & prams: An outdoor course over uneven, sometimes muddy terrain — not suitable for prams or mobility devices on the course itself. Bring a full change of clothes.
Planning tip: A great morning burn-off for active primary-schoolers on a fine day; bank it as an outdoor break between city days.
