Emblem of Aqua World Oarai

Our emblem uses a shark for its motif. The shark is at the top of the sea’s food chain.

The shark is a very mysterious creature that has evolved for 400 million years. Here at Aqua World Oarai, we put a lot of effort into shark breeding. We aim to breed the widest variety of sharks out of all of the aquariums in Japan.

The three rings of the emblem represent the following:
– Oarai/Ibaraki/The World
– Japan Current/Current Rip/Oyashio Current
– Past/Present/Future
