The park is built on the site of a former coastal landfill reclaimed from Tokyo Bay.
The obstacle course includes a signature 'water crossing' section where visitors must navigate ropes over a shallow pond.
The facility was designed with a historical theme reflecting the local area's Edo-period landscape.
It is the largest field athletic course in the 23 wards of Tokyo.
Many of the wooden obstacles are maintained to simulate the look and feel of traditional timber craftsmanship.
Heiwa-no-mori Park Athletic Field is a large-scale outdoor obstacle course park located within the larger Heiwa-no-mori Park in Ota, Tokyo. The facility features 40 distinct athletic stations constructed primarily of wood and rope, designed to test agility and balance. It is specifically modeled after traditional field athletics, emphasizing climbing, crawling, and maneuvering over water and land-based hazards. The course is built to accommodate both adults and children, requiring active physical participation rather than passive observation. The park utilizes natural topography, incorporating small ponds and grassy embankments into the circuit design. It serves as one of the most significant public outdoor physical education facilities managed by Ota City.
The rope bridge section crossing over the central pond provides the most scenic action shot.
