Ojima Komatsugawa Park

A free zoo with red pandas, Humboldt penguins and guinea pigs to pet, beside the park's Japanese garden.

Ukiyo-e prints hang in a concept room drawn from Edo-period picture books, alongside a Pokémon room and loft-bed and tatami apartments.

An earthquake simulator, a smoke room, a storm of wind and heavy rain to stand in, and a VR disaster experience for second graders and up, all free.

Big wooden climbing structures, a Tarzan rope, a woodworking room and play leaders on hand, in an adventure playground run by the ward.

Suites that sleep up to six, a restaurant looking out at Skytree, and a free shuttle to Disney for guests, with the airport limousine bus stopping at the door.

An original 1927 Ginza line car and the first Marunouchi line car side by side, and a driving simulator modeled on a Chiyoda line train.
