We took a bus all the way from Naha to Okinawa Churaumi Aquarium. The aquarium goes up to four floors, with tanks containing deep sea creatures, coral and tropical fish. The main Kuroshio Sea Tank holds an enormous 7,500 cubic metres of water, stretching from the first floor all the way to the second floor of the aquarium.

Shuri Castle served as the center of politics, foreign affairs and culture of the Ryukyu Kingdom since the 14th century, until Okinawa became a Japanese prefecture in 1879. The World Heritage Site with its brilliant colors and stylish Ryukyu architecture is strikingly different from any castle I have witnessed in all of Japan.
