The Ryūkyū Kingdom ruled most of the Ryukyu islands between the 15th and 19th centuries and was a prosperous trading nation due to it's tributary relationship with Ming Dynasty China. During this period many Gusukus (castles) were built. The Kingdom was invaded by Japan in 1609 and found itself in a period of dual subordination to Japan and China until 1872 when the Japanese government abolished the Kingdom and renamed it Ryukyu Han (Ryukyu Fief). In 1879, Japan annexed the islands and Ryukyu Han became Okinawa Prefecture.
During WWII, the Allies planned to use Okinawa as a base for air operations during their invasion of the Japanese mainland.
The 82 day long Battle of Okinawa (April - June 1945) was the largest amphibious assault and one of the most intense battles in the Pacific war. A quarter of Okinawa's civilian population was lost in the battle.
Okinawa was under US administration from the end of WWII until 1972 when the US government returned the islands to Japanese administration. The US has maintained a large military presence in Okinawa, leading to controversy and some resentment.
The Okinawa Prefecture encompasses the southern two thirds of the Ryukyu Archipelago which consists of approximately 160 islands (48 of which are inhabited) of varying sizes stretching for 1,000 kilometres from east to west and 400 kilometres from north to south in between the Philippine Sea and the East China Sea - from Kyūshū (in the southwest of Japan) all the way to Taiwan.
Okinawa is a place of natural beauty with white sand beaches, enticing clear blue water and vibrant coral reefs. Old-growth forests untouched since ancient times and mangrove jungles are home to precious rare animals and plants such as the Iriomote cat, one of the world's rarest and most endangered cat species.
Arts and culture are very important in Okinawa. Okinawa has 9 World Heritage Gusuku Sites from the Ryūkyū Kingdom, the most visited being the beautifully restored Shurijo Castle in Naha. You can also shop for attractive craftworks of crisp and colourful Ryukyu glass and laquerware, hand-created Okinawan pottery; visit the Prefectural Museum and Art Museum and roam around the malls, public market, streets and arcades soaking in the sites and sounds of Naha. Food is also an integral part of Okinawan culture and there are many local izakayas to try traditional Okinawan dishes.
In the less populated north of Okinawa Island is one of the world's largest aquariums, Churaumi Aquarium, Hiji Falls and Cape Hedo.
Okinawa supports plenty of water activities including scuba diving, snorkeling, deep sea fishing, spear fishing, surfing, sailing and simply enjoying the many beautiful beaches around the islands. For snorkelers and scuba divers stopping on Okinawa Island a trip to the Kerama Islands is a must!
Okinawa has a sub-tropical climate and experiences warmer weather than mainland Japan. The winter months from November to March has smaller crowds and fantastic visibility. However the seas can be choppy due to the strength of the dominant winds. Winter temperatures range from a minimum of 10°C to 20°C and the water temperature rarely drops below 19°C. Inter-island ferry services are much less frequent in winter.
The more crowded, hotter and humid summer starts in April and extends into September. Temperatures hover around 34°C and the water is about 29°C. The wettest period is from early May to early June. Typhoons may hit the area in July and August and sometimes extend into October.
Humpback whales breed in the area between December to March. February is the best month to snorkel with the whales. Manta rays and dolphins can be seen between May to November. Fish life is particularly abundant between August to December.

Okinawa's surrounding waters are fed by the warm Kuroshio current running north from the Philippines, bringing a huge variety of marine life to the islands. The warm sub-tropical climate facilitates diving year round. Species of reef fish, marine mammals and sea turtles that inhabit Okinawan waters total more than 1,000, while reef building corals exceed 200, making Okinawa amongst the larger coral habitats in the world. The underwater topography varies between the islands.
There are over 80 dive sites around Okinawa and the surrounding islands. Visibility can sometimes reach over 40 metres and currents can be strong at some sites. The Kerama Islands have some of the best scuba diving and snorkeling options.
The main island has dive sites in the north, south and mainly on the western side where there is a drop off. Some sites are beach dives but most are accessible by boat.
Easily accessible by snorkelers and divers. This famous, half submerged cave is named for the blue water created by the sunlight reflecting off the sandy white bottom. Find rock shrimp, pipefish and moray eels inside.

"man rock" is one of the best sites in the Keramas for advanced divers. The steep cliffside of Ugan drops to 40 metres in some place. Riding the current around the rock, you may be able to spot several crevices with lots of lionfish in them.

Sightings of dogtooth tuna, napoleon wrasse, turtles and sharks increase with the current.
Has sea fans up to 2 metres in diameter. Often has visiting manta rays.
