This Okinawa Churaumi Aquarium is fantastic!
Huge aquarium with 10m deep gigantic tank with 3 whale sharks.
Don’t miss the feeding times at 3pm and 5pm.
Also amazing dolphin show and sea turtles.
See the Okinawa Churaumi Aquarium website which has great info in English.
Also, note that the Dolphin Shows and the Turtle Feeding is FREE!
We stayed at a hotel very close to the Aquarium, so we actually went there a couple of times to see the shows with our baby. He loved it!
