Tokyo Water Science Museum

Sand and a rocky shore wrapped around a cove, with lawns, an observation deck, the Skywalk, and sunset and night views across the water.

About 7,000 square meters of miniatures, from Kansai Airport to the Evangelion hangar, and a 3D scanner that makes you a 1/80 figure for the scenes.

Painted illusions you pose inside for photos, an Edo-themed gallery, rooms that make you look giant or tiny, and a treasure hunt for hidden items.

An indoor play park with a giant jungle gym, ball pool, trampolines, a bouldering wall and ride-on games, plus a pretend-play corner.

Tokyo's streets rebuilt in LEGO in Miniland, a coaster and a shooting ride, a 4D cinema, NINJAGO City Adventure and a DUPLO playground.

A Bornelund indoor play world with attractions best for kids three and up, every child coming in together with a grown-up.
