The park is located at the specific geographic point where the Maruko River flows into the larger Tama River.
The name 'Hyogojima' historically refers to the shape of the landmass formed at the river junction.
The park functions as part of the Setagaya City flood mitigation infrastructure along the Tama River basin.
During low tide, the riverbank becomes a shallow marshy area used by local residents for nature observation.
Hyogojima Park is a waterfront green space situated at the confluence of the Tama River and the Maruko River in Setagaya, Tokyo. The park features a tiered concrete embankment that provides direct access to the water's edge, allowing visitors to walk along the riverbed during low tide. The park grounds include open lawn areas designed for picnicking and recreational activities. Its geographical orientation makes it a popular destination for viewing sunsets over the Tama River valley. The area serves as a flood control zone, which influences its open-terrain landscape design. Pedestrian pathways connect the park to the wider Tama River cycling and walking trail network.
