Fuchunomori Park

Right beside Chofu Airfield, with a hill that looks out over the runway where small twin-prop planes take off and land, and play equipment for toddlers.

Wide lawns along the Nogawa river, a nature garden with its own visitor center, and a free athletic course with wooden play equipment.

Historic Tokyo buildings rebuilt on one site, with a 1929 bathhouse you can walk into, a street Spirited Away's artists drew on and an old streetcar to board.

There's a big concrete slide and a Tarzan rope in the play plaza, plus a bouncy dome, an artificial-turf sledding hill and a C57 steam locomotive.

A gondola carries you from the station up to the gate, and one whole area is factory-themed rides and workshops, including a splash ride based on instant noodles.

A five-room mock-up of an animation studio, a giant Catbus for kids 12 and under to play in, and the five-meter Robot Soldier in the rooftop garden.
