Musashinonomori Park, Metropolitan park in Musashino region, Japan

Musashinonomori Park is a Tokyo metropolitan park opened on 1 April 2000, covering about 385,750 m² across Fuchu, Chofu and Mitaka. Chofu Airfield divides it into a north and a south section, and the north section holds the park service centre. Its grounds contain the Asahi football pitch, tennis courts, baseball and softball fields, a football and rugby ground and the Nishimachi football pitch.

The Tokyo Metropolitan Park Association opened this green space in 2000 as a new recreational area in the city. Its location next to Chofu Airport became an important feature of the site's geography.

The park's name refers to the Musashino region, and its grounds are split into a north and a south section by Chofu Airfield. The north section holds the service center that manages the whole park. From the grounds visitors watch and photograph aircraft taking off and landing on the adjacent runway.

The park is split into a north and a south section by Chofu Airport, so plan which side you want: the service centre that manages the grounds is in the north section. Hitomi-kaido (Tokyo Route 110) runs between the sections, and Nogawa Park lies 200 m north of that road. Runwayside spots let you watch aircraft taking off and landing up close.

The park served as the starting point for the cycling road races during the 2020 Olympics. This made it a key location for one of the world's most watched sporting events.
