Okinawa Churaumi Aquarium

The Okinawa Churaumi Aquarium, formerly known as the Okinawa Ocean Expo Aquarium, is a public aquarium located within the Ocean Expo Park in Okinawa, Japan. The aquarium's Kuroshio sea tank was the largest aquarium tank in the world until it was surpassed by the Georgia Aquarium in 2005.

The aquarium has the exhibit, "Encounter the Okinawan Sea", which reproduces the sea of Okinawa and most of the creatures that live in it. Churaumi was selected as the name of the aquarium by public vote amongst Japanese people: chura means "beautiful" or "graceful" in the Okinawan language, and umi means "ocean" in Japanese.
