Churaumi Aquarium

About this Attraction

Churaumi Aquarium (美ら海水族館, Churaumi Suizokukan) is one of the most celebrated and impressive aquariums in Japan, and a must-visit destination in Okinawa Prefecture. Located within Ocean Expo Park in northern Okinawa Main Island, the aquarium was built on the former grounds of the 1975 International Ocean Expo and was completely redesigned and reopened in 2002. Today, it stands as a symbol of marine education, conservation, and Okinawa’s deep connection with the sea.

The centerpiece of the aquarium is the awe-inspiring Kuroshio Tank, named after the Kuroshio Current—one of the world’s most powerful ocean currents. This enormous tank, measuring 35 meters in length and containing 7,500 cubic meters of water, is one of the largest in the world. It gives visitors a rare and mesmerizing view of giant whale sharks, graceful manta rays, and a variety of colorful marine species swimming together in harmony. The sight of a whale shark gliding slowly across the glass is unforgettable and often described as the highlight of any visit to Okinawa.

In addition to the Kuroshio Tank, Churaumi Aquarium features multiple levels of marine exhibits showcasing the diverse ocean environments around Okinawa—from shallow coral reefs to deep-sea ecosystems. Outdoor areas like the sea turtle pool, manatee habitat, and dolphin lagoon provide additional interactive learning experiences for visitors of all ages.

Churaumi Aquarium is not just an attraction but an educational hub dedicated to marine research and ecological preservation. Its engaging design, rare marine life, and world-class facilities make it a standout not only in Japan but across Asia. Whether you’re traveling with kids, a nature lover, or simply curious about the ocean, a visit to Churaumi is a journey into the heart of Okinawa’s underwater world.
