Kashinomiya Park, Public park in Hamadayama, Japan

Kashinomiya Park is a 4.3-hectare ward-run park in Hamadayama 2-chome, Suginami, Tokyo, opened on 30 October 2004. It has a lawn area, a pond, tennis courts, and a Japanese garden with a tea house. As a disaster-preparedness facility, it also contains emergency supply warehouses and a disaster well.

The park was created as a new recreational facility for the Suginami area, completed and opened by local authorities in October 2004. This development was part of efforts to enhance the residential neighborhood.

The park's Japanese garden and tea house give visitors a place to see traditional garden design and tea ceremony settings within a public park. The name Kashinomiya is written 柏の宮, using the character for oak, kashi. The grounds also hold a tennis court and pond.

The park is accessible from the address 2-5-1 Hamadayama with multiple entry points that make different sections reachable. The best times to visit are outside the hottest hours of the day, especially when local events are taking place.

The site was formerly a baseball ground owned by the Industrial Bank of Japan; when the bank merged into Mizuho, Suginami Ward bought the land and turned it into a park, which opened on 30 October 2004 and covers 4.3 hectares, the largest ward-run park in Suginami.
