Saitama Children's Zoo

Finnish and Danish shops and Scandinavian food along the shore of Lake Miyazawa, with canoes on the lake and play nets strung through the forest.

The Moomin family's house, a 400-meter zipline, and Emma's theater, where kids sing and dance along with Moomintroll.

36 real train cars around a turntable with a C57 steam locomotive on it, an E5 Shinkansen simulator and a mini train kids drive on a 300-meter track.

Spread out below the dam of Lake Tama, with a pond, a playground with swings and a sandpit, and a cycling path that loops all the way around the reservoir.

White tigers, alpacas to feed, and about 30 rides, among them a wooden coaster that runs out over the water.

More than 160 hectares, with a cycling course, bouncy domes in the children's forest, and a lawn about the size of two Tokyo Domes.
