Harumi Rinkai Park

Kids run their own little city here, choosing real world jobs and earning play money as they go.

Another excellent free science stop, with interactive exhibits that make energy and city infrastructure feel surprisingly fun.

You take your shoes off and walk through water, light and giant digital rooms, so it feels more like play than an art museum.

A big playground right by the water and shopping center makes this an easy reward before or after errands.

Huge miniature worlds full of moving trains, rockets and tiny surprises make this surprisingly absorbing even for younger kids.

The apartment layout gives you a kitchen and dining space, which is a huge quality of life upgrade with little kids.
