The Okinawa Churaumi Aquarium on the Motobu Peninsula is one of the largest and most spectacular aquariums in the world, and northern Okinawa’s headline attraction. Its centrepiece is the colossal “Kuroshio Sea” tank, where enormous whale sharks and graceful manta rays glide behind one of the planet’s biggest acrylic viewing panels. Set within the seaside Ocean Expo Park, it’s a must-visit for families and anyone heading north, easily combined with beaches, dolphin shows and gardens.

This guide covers the main tanks, tickets and discounts, the best time, the wider park and how to get there.
