The park was designed as part of the Tokyo Metropolitan Government's 'Super Levee' project to protect against flooding.
The name 'Shioiri' refers to the historical design feature where river water was allowed to flow into a basin to control water levels, simulating natural tidal movement.
The park contains a central fountain plaza specifically engineered to accommodate emergency water storage in the event of a disaster.
The park's layout was intentionally integrated with the surrounding Minamisenju residential developments to act as a firebreak zone.
Certain zones of the park contain wetland-style vegetation designed to promote biodiversity along the Sumida River corridor.
Shioiri Park is a large, multi-functional riverside public space located along the Sumida River in Arakawa City. The park is distinguished by its 'Shioiri' (tide-entering) theme, featuring landscapes designed to reflect the historical nature of the tidal Sumida River. It offers expansive open lawns, specialized barbecue areas, and extensive jogging paths that connect to the broader Sumida River cycling route. The park is divided into several zones, including a large playground with unique climbing structures and designated areas for birdwatching. Vegetation is curated throughout the park with seasonal flower beds that vary by arrival of the spring and autumn blooms. The park serves as a designated disaster-prevention base for Arakawa City, equipped with emergency facilities integrated into the landscape. Panoramic views of the Tokyo Skytree are visible from the riverbank edge of the park. It functions as a local recreational hub that balances active sports facilities with passive riverfront leisure.

Use the dedicated barbecue booking system in advance if planning to grill, as spaces are popular with locals.
Bring a picnic mat to utilize the large grass areas, which are the most comfortable spots for river watching.
Visit the riverside path during low tide to observe the natural mudflat ecosystems that form at the water's edge.
Do not attempt to use the barbecue areas without prior reservation, as on-site registration is not permitted.
Keep noise levels low near residential zones; pack out all personal trash as there are limited public bins.
