Okinawa Churaumi Aquarium

Widely considered one of the world's most spectacular marine facilities, Okinawa Churaumi Aquarium serves as the crown jewel of Ocean Expo Park. The centerpiece is the massive Kuroshio Sea tank, one of the largest in existence, where majestic whale sharks and giant manta rays glide past a monumental acrylic window. The journey begins with shallow-water coral reefs and descends into the mysterious depths of the surrounding Okinawan waters. Beyond the main building, visitors can explore manatee and sea turtle exhibits or enjoy dolphin performances against the backdrop of the shimmering East China Sea, offering an immersive look into the rich biodiversity of the Ryukyu Islands.
