Okinawa is located midway between Tokyo and Southeast Asia and is Japan's southernmost point. The islands are approximately 1,000km east to west and about 400km north to south. The prefecture is composed of 160 islands extending over a vast area of ocean. There are 48 inhabited islands in the group. While being Japan's southernmost point, Okinawa is also located close to many of the nations of East Asia. Vladivostok, Beijing, the Democratic People's Republic of Korea, The Republic of Korea, Taiwan, Hong Kong, the Philippines, and Guam are all located in the 2,500km radius of Okinawa that extends up to Hokkaido.

@The average temperature is 22Ž, around 5.3Ž higher than Kagoshima. Average annual precipitation is over 2,000ml, average humidity is 76%, and the islands enter the rainy season about a month earlier than mainland Japan. Okinawa also has higher temperatures and humidity in the summer months. The heavy rainfalls are similar to the tropics. The warm mild climate is influenced somewhat by the Kuroshio Current and the intense heat of summer is softened by its sea breezes. Seasons are not as clearly defined as in mainland Japan because Okinawa belongs to the subtropical zone and has an oceanic climate. The islands receive seasonal winds from East Asia with strong winds coming in during the winter months from the northeast. The seasonal changes can be characterized as a combination of subtropical oceanic climate and the weather brought on by seasonal winds from East Asia. Okinawa is the northern limit for Southeast Asian flora, and species such as the Gajumaru Banyan (Ficus retusa) and Deigo Indian Coral Bean (Erythrina variegata) as well as other tropical and subtropical plants and flowers inhabit the islands.

@The archipelago is extends in an arc shaped line between the Japanese island of Kyushu and Taiwan. Approximately ten million years ago, it connected the southern region of the Asian continent to the islands of Japan. During that time, many species of fauna migrated to Okinawa. By about twenty to ten thousand years ago it was finally separated, after which evolved the unique animals which inhabit the Ryukyu archipelago. The Yanbaru area in the northern part of Okinawa Island is home to endangered species such as the Noguchigera woodpecker (Sapheopipo noguchi) and the Yanbaru Kuina (Rallus okinawae) or Okinawan Rail. The island of Iriomote is inhabited by the Iriomote Yamaneko wildcat (Mayailurus iriomotensis) and other rare and important species of fauna. For the many rare and diverse flora and fauna that can be seen on the islands, Okinawa has been called the Galapagos of the East. With its many coral reefs, Okinawa boasts of some of the world's most beautiful coral treasure houses. The reefs protect the islands from natural disasters and provide abundant fishing. The reefs are an integral part of the lives of people here. In this way, Okinawa's geographic location and climate have woven a distinctive natural environment.
