What Is the Okinawa Churaumi Aquarium?
The Okinawa Churaumi Aquarium is a large aquarium located in Motobu Town in the northern part of Okinawa's main island, inside the Ocean Expo Park (a national government park commemorating the Okinawa International Ocean Exposition).
The exhibits are designed so that you trace Okinawa's seas, progressing from coral reefs to the Kuroshio Current and into the deep sea.
You enter from the 3rd floor, then move down to the 2nd and 1st floors, with the design making it easy to follow the gradual descent into deeper waters.
For first-time visitors, the order of the exhibits itself helps you better understand the seas of Okinawa, which is one of the aquarium's biggest features.

Top Exhibits to See at Okinawa Churaumi Aquarium
Whale Sharks and Manta Rays in the Kuroshio Sea Tank
The aquarium's most iconic exhibit is the massive "Kuroshio Sea" tank, which holds about 7,500 cubic meters of water.
In this tank, you can observe whale sharks (Jinbē-zame) and oceanic manta rays (Nanyō Manta) swimming together from multiple angles.
In addition to the large acrylic panel at the front, you can also enjoy the "Aqua Room," where fish swim overhead, and special seating that lets you view the giant tank head-on, with each viewing spot offering a different impression.
Even with the same tank, the experience changes depending on whether you take in the whole view from afar or follow the movements of the fish up close.
Feel the Spirit of Okinawa's Sea at the Coral Sea Tank
The "Coral Sea" tank has no roof, allowing natural Okinawan sunlight to pour directly into the water.
It also uses an open-system design that pumps fresh seawater straight from the ocean in front of the aquarium, supporting the large-scale display of about 80 species and 400 colonies of reef-building corals.
This exhibit captures a landscape closely resembling Okinawa's actual sea, complete with vibrant tropical fish, making it a place worth taking in slowly with your eyes rather than just through a camera lens.
Deepen Your Visit by Reaching the Deep-Sea Exhibits
On the 1st floor, the "Journey to the Deep Sea" introduces a wide range of deep-sea creatures from the waters around Okinawa, along with displays about deep-sea research, breeding, and exploration.
The transition from the bright coral reef exhibits to the quiet, mysterious world of the deep sea creates a striking experience.
The "Deep-Sea Tank" recreates depths beyond 300 meters, showcasing rare deep-sea creatures such as ruby snapper (Hamadai), boxer crabs (Hakoebi), and the parent and offspring of saw sharks successfully bred at the aquarium, which can only be seen here.
Walking the entire route helps you grasp the full breadth and depth of Okinawa's seas in a more vivid way.

Easy-to-Follow Route for First-Time Visitors
Follow the Floor Order to Grasp the Flow of Exhibits
According to the aquarium map, each floor has its own theme: 4F "Inviting Sea," 3F "Journey to the Coral Reefs," 2F "Journey to the Kuroshio," and 1F "Journey to the Deep Sea."
Rather than rushing only to the tanks you want to see, following the order of the exhibits will help you grasp the bigger picture.
For an average visit, plan on spending about 1.5 to 2 hours touring the aquarium.
