The park was created around the Toneri Oike Pond, a reservoir that once supplied local agricultural irrigation.
It hosts one of the largest concentrations of cherry trees in the Adachi ward, with over 1,000 specimens.
The park contains a designated 'Wild Bird Sanctuary' area to support local urban biodiversity.
The park spans two distinct city blocks connected by a pedestrian bridge over the public road.
During the winter, the park pond attracts migratory birds that are not present during the warmer months.
Toneri Park is a large-scale metropolitan park in Adachi City, covering over 60 hectares of land originally reclaimed from a former pond. It features the notable Oike Pond, which serves as a central hub for waterfront activities and serves as a habitat for various waterfowl. The park grounds contain comprehensive sports facilities including baseball fields, tennis courts, and a multi-purpose athletic field. Expansive lawns and groves of trees provide significant open space for local community recreation. The site is characterized by its wide, paved walking paths that circle the water and traverse the wooded sections. It serves as a significant green lung for the northern Tokyo area. The park layout is designed to balance active sports zones with passive nature viewing areas.
