A tiny red train runs through this bright miniature town built specifically for young children.

Ordering from the screen and watching plates arrive is half the entertainment, and there are plenty of non sushi choices.

A good base when you want apartment style space, a kitchen and enough beds for everyone without booking two rooms.

Kids can try earthquake and fire simulations, which turns disaster preparedness into something memorable and hands on.

The enormous garden is the special part, with paths, bridges and seasonal scenery that give kids somewhere to wander between plans.
