Looking for kid-friendly ideas

Hi all, my wife and I have already been to Okinawa several times before we had our baby. Daughter will be about 11 months when we visit next and I’m looking for travel ideas or things to do that are kid-friendly.

Obvious suggestions (like the aquarium) are welcome, but really looking for some “local insight” as I’m really into Japanese culture / travel and still want to explore!
