Okinawa prefecture is the perfect tropical getaway that you wouldn't initially associate with Japan. Along with the almost heavenly Miyakojima and Ishigakijima islands that offer crystal clear water, beautiful beaches and that perfect relaxing atmosphere, the main island of Okinawa also has a lot to offer. Along with its unique atmosphere and culture different to that of the rest of Japan, Okinawa also has one of the most impressive aquariums in the world that is home to two huge whale sharks that you can see through a multi-story tank where they peacefully reside along with hundreds of other sharks, rays and fish. So sit back and relax, and enjoy some Okinawan cuisine during your stay in Japan.
