Did you visit “Okinawa Churaumi Aquarium“? Chura means beautiful in Okinawa direct. When I was high school, I went to there with my friends as a school field trip. There are many different fishes such as whole sharks, mantas, dolphins, fur seaks and something like interesting fishes. This is famous for raising many whole sharks. It’s one of the most rare things. In addition, there are corals. This reproduce natural Okinawa sea. It is very beautiful and amazing. I was very moved. The cost of the ticket is 1800 yen. It is open till 21 p.m. during summer. If you have a chance to go Okinawa, you should go!
