Shakujii Park is a designated metropolitan park in Nerima, Tokyo, featuring two distinct ponds, Shakujii-ike and Sanpoji-ike. It covers approximately 23 hectares and serves as a significant site for both recreational boating and archaeological history. The park houses the ruins of Shakujii Castle, an ancient fortress of the Toshima clan from the Kamakura and Muromachi periods. Sanpoji-ike pond is recognized for its unique marsh vegetation, including swamp cypress and water lily colonies. The park acts as a vital urban green space, connecting to the surrounding Musashino landscape. It remains open to the public year-round and offers a specialized boat rental facility on the southern pond. The terrain includes a mix of wooded areas and open grassy spaces suitable for birdwatching and leisurely walking.
The wooden bridge crossing over Shakujii-ike provides a panoramic view of the lake surface and the reflection of the surrounding forest.
Bring a pair of binoculars if you enjoy birdwatching, as the wetlands attract a variety of local and migratory species.
Explore the northern section of the park to see the ruins of the moat and the earthworks associated with the historic castle site.
Visit on a weekday to avoid crowds, as the park is a popular local spot for families during weekends and public holidays.
Do not attempt to walk through the marshy wetland areas near Sanpoji-ike, as these are protected zones closed to pedestrians.
Take all trash with you as there are few public bins; refrain from feeding the wild water birds.
