Rainy day things to do in Okinawa with kids 4 spots
Okinawa is a subtropical island chain in Japan's far south, warm enough to swim when the mainland is cold. Much of its sea stays shallow a long way out, so small children can play in water they can stand up in. It suits families who want beach days with young children.
Okinawa's gateway, with a monorail from the terminal reaching central Naha in 13 minutes.

The domestic and international sides connect on foot through the 2F walkway (YUINICHI STREET) of the joined building. The kids' play area is on the 2F right by the security checkpoint, and the nursing rooms are on the 1st, 2nd, and 3rd floors plus the international 4F food court area.
The aquarium is a four-story reinforced concrete building, and inside it has slopes throughout so you can go around with a stroller. The walk from the parking lot is long enough that the aquarium asks visitors to allow extra time. Its average visit of 1.5 to 2 hours does not include Okichan Theater, the Dolphin Lagoon, the Sea Turtle Pool, or the Manatee Pool.
The aquarium connects directly to the second floor of the Iias Okinawa Toyosaki shopping mall, and that is where you go in. Its two floors — the forest on 2F, the sea on 1F — are linked by elevators and slopes on every floor. The aquarium's own floor guide says it works for rainy days and small children.
The WiFiBOX counter is in the domestic first-floor arrival lobby and the GLOBAL WiFi counter is in the international first-floor arrival lobby. Both are inside the arrival lobby itself, so you can stop by right after picking up your bags.
