Aichi with preschoolers (4–6) 3 spots
Aichi is Japan's factory heartland, flat and quick to cross. Ghibli Park is here, Totoro's world built at full size, and the companies that make Japan's cars and bullet trains keep museums where you climb into the real thing.

Houses from around the world, rebuilt full-size along a 2.5 km loop.

At five or six the choosing is the event: which country to be for the day is a real decision. This is also the first age that can walk the whole loop instead of riding it.Gem hunting, the Taiwanese night market and the after-dark opening are the extras this age would ask for. All three run on summer weekends only: in 2026, from July 25 to August 30, plus August 10 to 14.
The grounds are big enough that a kindergartner can tire: one girl walking around the keep said she could not walk any more and had to be carried. The exhibits are also aimed at adults, and a travel company article says children of elementary school age and up enjoy it more.
Arriving at the 9:00 opening on a quiet weekday, one family with a 6-year-old and a 2-year-old was up the keep and back down within an hour. Still, the balcony's height made that 6-year-old step back, a little scared.
