Crayonhouse Tokyo

A path where free-roaming Japanese squirrels run around you, a guinea pig petting corner, and a merry-go-round for small kids.

Rowboats, cycle boats and swan boats on the pond the Kanda River starts from, and the Inokashira Benzaiten shrine.

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.

One big grass field on the site of an old aircraft factory, plus a play equipment area.

Free, with exhibits on the history of anime and how it's made, a booth to try dubbing, a theater showing anime and a library of videos to watch.

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