The Coral Sea
The Coral Sea tank is open to the sky, so that Okinawa's powerful sunlight can reach it directly. Such large-scale cultivation of coral has been made possible by utilizing a system that continually supplies fresh sea water from the offshore waters close by the Aquarium. It is quite a sight to see approximately 800 colonies composed of 70 different reef-building coral.
The Coral Sea tank was created based on ideas that our staff received while diving locally and observing the coral reef every month. The coral in this tank was first transplanted as small coral fragments which were collected by special permission and have been growing here for more than 10 years.

Marine life found in this area
Every June in Okinawa Churaumi Aquarium our coral colonies spawn eggs and sperm.
Coral spawning occurs during the night time, when the Aquarium is closed to visitors, but we always video the event for you to see!
The fertilized eggs produced by our Aquarium are returned to the Okinawan Sea, where they have a chance to grow up into corals.
