Okinawa Prefecture is the southernmost prefecture of Japan. It comprises hundreds of the Ryukyu Islands in a chain over 1,000 kilometres long. The Ryukyus extend southwest from Kyushu (the south westernmost of Japan's four main islands) to Taiwan. The Okinawa Prefecture encompasses the southern two thirds of that chain. Naha, Okinawa's capital, is located in the southern part of Okinawa Island.
