Japanese island Okinawa, where the second largest aquarium in the world is located in the north-west part of main Okinawa island in the National Government Park (Ocean Expo Park).
This is really an unforgetable adventure even for adults. Possibility to see deep see creatures, huge smiling mantas, beauty of coral, dolfines show and amazing whale sharks as well as the scenery of the national park and ocean cost. The glass underwater tunnels allow to watch all those see animals from a very close perspective when they swim just next to you and above your head. The beach was completely empty in December still looking amazing.
