Hachikokuyama, Metropolitan park in Higashimurayama, Japan

Hachikokuyama is a metropolitan park in Higashimurayama, Japan, that covers a low ridge with wooded areas and open fields. The park has a network of trails that run along the top of the ridge and branch into smaller paths, offering places to walk and observe nature.

The area was part of the ancient Tōsandō highway, and in 1333 Nitta Yoshisada set up a military camp on a mound within the park. The park was opened in 1990 to protect the green space from development.

The name of the park comes from a time when eight provinces could be seen from the top of the hill, though trees now block the view. Visitors can also explore the Hachikokuyama Taiken no Sato, a nearby facility with exhibits on local history and nature.

The park is free to enter and can be reached on foot from nearby train stations. There is no parking lot, so visitors should plan to arrive by public transport or on foot, and be prepared for uneven terrain on the trails.

The park is known as an inspiration for the anime film My Neighbor Totoro, and director Hayao Miyazaki has said it is where Totoro was born. A hospital near the park served as the model for the one in the film.
