Tatsumi Seaside Park, Seaside park in Koto City, Japan
Tatsumi Seaside Park is a waterfront park on Tokyo Bay, located in the Koto district of Tokyo, Japan. It covers open lawns, sports facilities, walking paths along the water's edge, and several activity zones spread across the grounds.
The park was built on land reclaimed from Tokyo Bay and opened in 1993 as part of a city-wide effort to develop the waterfront area. It was one of several projects intended to turn unused coastal land into public green space.
On weekends, families and school groups gather on the open lawns, while sports enthusiasts head toward the activity zones near the water. The park feels like a neighborhood space that locals use regularly, not just on special occasions.
The park is within walking distance of Tatsumi Station on the Yurakucho Line, though the walk takes a fair amount of time. The site is open year-round, but expect more visitors on weekends and public holidays.
The park is one of the few places in Tokyo where visitors can play disc golf, which draws groups looking for something out of the ordinary. It also has a dedicated dog run, which remains uncommon in Japanese urban parks.
