Oura Bay where various creatures coexist

 In Oura Bay,Nago Okinawa, new species are discovered every year. More than 5,800 creatures have been identified, and endangered species such as dugongs make their habitat. This is a hotspot for biodiversity. There is no such sea as Oura Bay even in Okinawa. Its value is said to be comparable to the World Heritage Site.

The blue coral communities in Oura Bay are 13 meters high, 30 meters wide and 50 meters long. It is said that it took thousands of years to grow to this size.
