Visit Okinawa Churaumi Aquarium
Motobu, Japan
The Kuroshio Sea tank is the centrepiece of Churaumi Aquarium, with whale sharks and rays moving through a vast blue space. Smaller exhibits explore coral habitats and deep-sea life, adding context to the spectacle. Set aside several hours, then leave time for the wider Ocean Expo Park outside. This is a long journey from Naha, so it fits especially well into a stay in northern Okinawa or a carefully planned day trip.
