Wakasu Seaside Park

Wakasu Seaside Park is a large, beautifully open waterfront park on the reclaimed land of Wakasu Island in Koto City, offering one of Tokyo's most spacious and genuinely peaceful free outdoor family destinations. Bordered by Tokyo Bay on one side and the emerald fairways of Tokyo Golf Club on the other, the park has a surprisingly rural, expansive feel that is remarkable given its proximity to the city center.

Families come to Wakasu for a variety of outdoor experiences: walking and cycling the park's well-maintained paths, picnicking on the wide open lawns, exploring the sandy beachfront along the bay, and in warmer months, setting up camp in the park's designated camping area — one of the very few camping options available within Tokyo's city limits. The campground makes Wakasu an appealing option for adventurous families wanting an easy overnight nature experience without leaving the greater Tokyo area.

Bicycle rental is available on site, making it easy to cover the park's sizable grounds with older children who can cycle independently. For younger kids, the open flat terrain is ideal for strollers and early walkers. Given the very limited food facilities, planning ahead with a packed picnic is essential for a comfortable visit.
