Heiwa-no-mori Park Athletic Field

Heiwa-no-mori Park Athletic Field — heiwa no mori meaning 'forest of peace' — is a spacious public sports and recreation area in Tokyo that provides families with generous open space for athletic activity, running, and outdoor play. The athletic field section features running tracks, open grass areas, and sports courts that families can use freely without reservation on non-event days. For families traveling with active older children and teens who need more than a playground to stay engaged, Heiwa-no-mori offers exactly the kind of unrestricted space that Tokyo's dense urban environment typically makes hard to find.

Bring a soccer ball, a frisbee, or a badminton set and simply play — the park supports that in a way that few central Tokyo spaces can. The surrounding forested park areas provide scenic walking routes through mature trees, quiet corners for picnicking, and a sense of nature that the athletic fields themselves cannot offer. Restroom and changing facilities are available, and the flat main paths are stroller-friendly.

The park is large enough that even on busy weekend days there is space to establish a family territory without feeling crowded. Located in the Shinagawa or adjacent ward area, it connects to transit with reasonable ease. For families planning an active Tokyo day, Heiwa-no-mori Athletic Field is a reliable, free, and spacious option that rewards physical energy with room to really move.
