The aquarium is really big and I very curious to see the whale sharks. The tank they live in is one of the or the biggest tank in the world I believe. The ticket was 1,850 yen, which in my opinion was a little on the steep side. In the end though, there was much to see. However I think that an after 16:00 ticket (1,250 yen) might be a bit more affordable. Also it gets a little bit less crowded after 16:00
Located in the north part of Okinawa. It took around 2 hours drive from Naha. You can also join 1 day tour just to visit here. Definitely worth visit! It is one of the largest aquariums in the world! Standing by the enormous tank which brings you the most breathtaking view! Whale sharks, manta rays, etc as if you are swimming with them under the sea.
