The Churaumi Aquarium (C, Churaumi Suizokukan) is widely considered Japan's best aquarium. It is the main attraction of the Ocean Expo Park on the former grounds of the 1975 International Ocean Expo in northern Okinawa Honto. The aquarium was completely redesigned and reopened in 2002.

The highlight of a visit to the Churaumi Aquarium is the massive Kuroshio Tank, one of the largest in the world. The tank takes its name from the warm Kuroshio current which plays a large part in the variety of Okinawa's of marine life. The tank contains a wide variety of species, the most striking of which are the giant whale sharks and manta rays.

The aquarium is spread out over three floors with the entrance on the third floor and the exit on the first floor. Directly after the entrance there is a pool where visitors can touch living starfish and seashells with their own hands. Next there is a tank with the world's first large scale exhibit of living coral.

The route through the aquarium then leads past the Kuroshio Tank, where visitors will likely want to spend quite a bit of time. Feeding shows are held twice daily. Located just beside the tank is a high definition movie theater about Okinawa's marine life.

Past the Kuroshio Tank there are a few more interesting tanks and displays including an area dedicated to sharks with live tiger sharks and bull sharks. Another area is dedicated to marine life in the extremely deeps waters of Okinawa and includes displays of various bioluminescent fish.

In addition to the main aquarium building, there are a few outdoor pools near the waterfront where animal shows of dolphins, sea turtles and manatees can be viewed free of charge. There are only a few shows per day, so visitors might want to check show times before entering the aquarium.

Getting there and around

The Churaumi Aquarium is part of the Ocean Expo Park on the Motobu Peninsula in northern Okinawa Honto, about 90 kilometers from Naha.

The Okinawa Airport Shuttle, the Yanbaru Express and bus line 117 directly connect the airport and city center of Naha with the Churaumi Aquarium. The one way trip takes a little over two hours and costs 2000 yen on the Okinawa Airport Shuttle and the Yanbaru Express and 2440-2550 yen on bus 117. There are 1-2 buses per hour. In central Naha, the Airport Shuttle and Yanbaru Express stop at the Prefectural Office (k, Kenchō Kitaguchi) while bus 117 stops at the Naha Bus Terminal.

Most buses along the lines 65 and 66 connect Nago with the Kinen Kōen-mae (LOO) bus stop in front of the Ocean Expo Park (50 minutes, 900 yen one way, 1-2 buses/hour). Note that about one out of three buses runs on a slightly different route that does not serve the aquarium.
