Chikyu no Niwa Tokyo Solamachi

Kirby's fluffy pancake and Waddle Dee burgers, with plates you can order as souvenirs, like the star-shaped glass one a dessert comes on.

Observation decks from 340 to 350 meters, one level with a glass floor to stand on, and a corridor at 450 meters with views all the way around.

Magellanic penguins in a 350-ton open indoor pool, about 700 jellyfish, and a lab where you watch jellyfish being bred.

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

The science of salt and the world's salt resources on one floor, and the story of tobacco, from the Maya site of Palenque to the Edo period, on another.

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.
