Okinawa Prefecture

History

Prehistoric and ancient history

The prehistoric history of Okinawa differs significantly from that of mainland Japan. Prior to written records, it is generally divided into two periods: the Paleolithic era and the Shellmidden period (Kaizuka period). The earliest evidence of human activity in Okinawa includes the Yamashita Cave Man, dating back approximately 32,000 years, and the Minatogawa Man from around 18,000 years ago. In 2012, the world's oldest known fishhook was discovered in the Sakitari Cave site in Nanjo City, Okinawa Prefecture.

The Shellmidden Period in Okinawa roughly corresponds to the Jōmon through Heian periods of mainland Japan, with a chronological gap of about 10,000 years from the Paleolithic era.

At the Kogachibaru Shell Mound, archaeological findings include pottery styles such as Sobata and Ichiki, which originate from the Kyushu region, obsidian from Koshidake in Saga Prefecture, and jade from Itoigawa in Niigata Prefecture used for ornamental pendants. These discoveries indicate that close exchanges with Kyushu were already taking place during this time.

However, by the middle of the Shellmidden Period, Okinawan pottery began to exhibit clearly localized characteristics. Examples include the Iha and Ogido pottery styles, which are distinct to the region.

In contrast to the Shellmidden culture of Okinawa Island, which was influenced primarily by mainland Japan, the prehistoric cultures of the Miyako and Yaeyama Islands were shaped more significantly by southern cultures, including those from the Philippines.

Gusuku and Sanzan periods

From the 12th century onward, Okinawa entered the Gusuku period, characterized by the development of an agrarian society. During this time, populations moved from coastal dunes to more fertile limestone plateaus, leading to significant population growth and the beginnings of international trade. Local chieftains, known as Aji, constructed fortified residences called Gusuku to protect their territories and expand their influence through foreign trade. Gusuku sites are found throughout the Ryukyu Islands, from the Amami Islands in the north to the Yaeyama Islands in the south, with estimates ranging from 300 to 400 sites in total. Early Gusuku were generally small, covering about 1,000 square meters, but larger fortresses appeared in later periods.

By the 14th century, Okinawa Island was divided into three polities, marking the beginning of the Sanzan period. These were the Kingdom of Hokuzan, centered at Nakijin Castle in the north; the Kingdom of Chūzan, centered at Urasoe Castle in the central region; and the Kingdom of Nanzan, centered at Ōzato Castle in the south.

According to official histories compiled by the royal government in Shuri—such as the Chūzan Seikan, Chūzan Seifu, and Kyūyō—the first royal lineage of Ryukyu was the legendary Tenson dynasty. After internal conflict during its 25th generation, a local Aji named Shunten from Urasoe was supported by the people, quelled the unrest, and was crowned as the first king of the Ryukyu Kingdom. However, these early historical accounts are heavily mythologized, and even if Shunten was a real historical figure, he likely ruled only the Urasoe area as an Aji. The Shunten dynasty lasted for three generations before being overthrown by the Eiso dynasty, which in turn was replaced by the Satto dynasty after four generations. By this time, Okinawa Island had effectively split into the three kingdoms of Hokuzan, Chūzan, and Nanzan.

In 1372, the Ming dynasty of China dispatched an envoy, Yang Zai, to the Kingdom of Chūzan, requesting the king, Satto, to enter into a tributary relationship. Satto agreed, and soon after, the kings of Nanzan (Chōsatto) and Hokuzan (Hanishi) also began paying tribute to the Ming court, bringing all three kingdoms into the Chinese tributary system.

In 1406, the Aji of Sashiki, Shō Hashi, overthrew King Bunei of the Satto dynasty and installed his father, Shō Shishō, as king, establishing the First Shō Dynasty. In 1416, Shō Hashi capitalized on dissatisfaction among the Aji of Hokuzan with their king, Hananchi, and conquered the kingdom. The Kingdom of Nanzan, plagued by internal conflict under the rule of Tarumoi, was defeated by Shō Hashi in 1429, completing the unification of Okinawa Island under the Chūzan Kingdom.

Ryukyu Kingdom period

The First Shō Dynasty experienced political instability due to the early deaths of several kings. After the death of the fifth king, Shō Kinpuku, a succession dispute known as the Shirii-Tumui rebellion broke out. Order was eventually restored when Shō Taikyū ascended as the sixth king. During his reign, another major conflict, the Gosamaru–Amawari rebellion, occurred, but Shō Taikyū was able to suppress it. His successor, King Shō Toku, was known as a tyrant. After his death, a coup led by royal officials installed the high-ranking bureaucrat Kanemaru as king. Kanemaru took the royal name Shō En, founding the Second Shō Dynasty.

Under the rule of the third king of the dynasty, Shō Shin, a centralized administration was firmly established. Shō Shin relocated powerful regional chieftains (Aji) to the capital of Shuri and appointed state officials to govern the provinces directly. The territorial extent of the Ryukyu Kingdom also expanded, covering the area from the Amami Islands in the north to the Yaeyama Islands in the south. Culturally, this era was a golden age for the kingdom, with significant development in the arts, religion, and architecture.

By actively participating in the tribute system with the Ming dynasty, the Ryukyu Kingdom received preferential treatment and became a key intermediary trading hub in East Asia. Many of the tribute goods presented to China originated from Japan, while Chinese goods were exported to Japan through Ryukyu. Southeast Asia, China, and Japan were Ryukyu's primary trade partners, and the kingdom also maintained trade with the Korean Peninsula. However, Ryukyu's significance as a trade hub declined in the 16th century with the Age of Discovery, as Portuguese and Spanish merchants entered East Asia, and China gradually relaxed its maritime prohibition policies.

The Miyako Islands and Yaeyama Islands had long been politically fragmented. In 1474, local strongman Nakasone Toyomiya of Miyako Island submitted to the Ryukyu Kingdom, bringing the island under centralized control. In 1500, Ryukyuan forces defeated Oyake Akahachi, the ruler of Ishigaki Island. In 1522, Nakasone Toyomiya conquered Yonaguni Island, completing the unification of the Yaeyama Islands under Ryukyuan rule. The Amami Islands in the north also came under Ryukyuan control by 1466.

In 1609, the Shimazu clan of the Satsuma Domain invaded the Ryukyu Kingdom in what is known as the Invasion of Ryukyu. King Shō Nei surrendered, and the kingdom became a vassal state under Satsuma's control. The Amami Islands were ceded to Satsuma as part of the settlement. While Ryukyu was partially integrated into Japan's feudal han system, it continued to function as a nominally independent kingdom and maintained its tributary relationship with China.Ryukyuan sovereignty was maintained since complete annexation would have created a conflict with China. The Satsuma clan earned considerable profits from trade with China during a period in which foreign trade was heavily restricted by the shogunate. Although Satsuma maintained strong influence over the islands, the Ryukyu Kingdom maintained a considerable degree of domestic political freedom for over two hundred years.

First Okinawa Prefecture period

Following the Meiji Restoration, Japan began its modernization process by abolishing the han system and establishing prefectures in 1871. That same year, the Mudan Incident occurred when a Ryukyuan ship drifted to Taiwan and its crew was killed by local indigenous people. This event became a pretext for Japan to assert control over the Ryukyu Kingdom. In 1872, Japan reclassified the kingdom as the Ryukyu Domain, a move known as the Ryukyu Disposition. To avoid backlash from the Qing dynasty and Ryukyuan royalty, the Meiji government initially designated Ryukyu as a "domain" rather than a "prefecture", a designation that had already been abolished in mainland Japan.

In 1874, another Ryukyuan shipwreck incident led to the Taiwan Expedition of 1874 (the Botan War), in which Japan dispatched troops to Taiwan. During post-conflict negotiations, the Qing acknowledged Japan's actions as "a righteous act of protecting its people." Japan interpreted this as de facto recognition of Ryukyu as Japanese territory and subsequently ordered the Ryukyu Domain to cease its tribute missions to China. This triggered internal division within the Ryukyuan court between pro-Japan and pro-China factions.

In March 1879, the Japanese government officially abolished the Ryukyu Domain and established Okinawa Prefecture, relocating King Shō Tai to Tokyo. Some Ryukyuan nobles and civilians fled to China and appealed to the Qing government to restore the Ryukyu Kingdom. Resistance in the Miyako and Yaeyama Islands was especially strong, culminating in the Kōchi Incident, in which locals killed a Japanese interpreter. However, the rebellion was eventually suppressed.

The Qing dynasty invited former U.S. President Ulysses S. Grant to mediate the dispute. Grant proposed a compromise in which the Okinawa Islands would go to Japan, while the Miyako and Yaeyama Islands would be ceded to China. The Qing countered with a plan that would return the Ryukyu Kingdom to the Okinawa Islands, assign the Amami Islands to Japan, and annex the Miyako and Yaeyama Islands to China. Ultimately, the negotiations failed. After the First Sino-Japanese War (1894–1895), the Qing ceded Taiwan to Japan and lost influence in the region, silencing calls for the restoration of Ryukyu.

In the early years of direct Japanese rule, a policy known as the Old Customs Preservation Policy (旧慣温存政策, Kyūkan Onzon Seisaku) was implemented, maintaining Ryukyuan land and tax systems, which slowed Okinawa's modernization. After the First Sino-Japanese War, Japan replaced this policy with an assimilation strategy, accelerating Okinawa's Japanization. However, Okinawa's strategic and economic importance declined, particularly after Taiwan became Japan's new southern frontier and sugar-producing center.

Postwar disposition disputes

During World War II, the Allied powers engaged in multiple rounds of discussions regarding the postwar status of the Ryukyu Islands. At the Cairo Conference in 1943, U.S. President Franklin D. Roosevelt proactively raised the issue of Ryukyu's sovereignty, suggesting that China might administer the islands after the war. However, Chinese leader Chiang Kai-shek responded only cautiously, proposing instead a joint occupation and international trusteeship. As a result, the Cairo Declaration made no explicit reference to the Ryukyus, instead stating that territories such as Taiwan and the Pescadores—seized by Japan—should be returned to China. Historians believe Chiang hesitated because he was unsure whether Roosevelt's offer was sincere or a diplomatic probe, and because the wartime Nationalist government relied heavily on American support and wished to avoid a territorial dispute.

As the Pacific War progressed, the U.S. military increasingly emphasized the strategic importance of the Ryukyus. In 1944, some U.S. officials proposed exclusive control of the islands to serve as a bulwark against Soviet expansion and threats from the Asian mainland. Roosevelt reportedly expressed to Joseph Stalin his support for returning the Ryukyus to China, but no formal agreements emerged from the Cairo, Yalta, or Potsdam meetings. The Potsdam Declaration stated only that Japanese sovereignty would be limited to the islands of Honshu, Kyushu, Shikoku, and Hokkaido, while other territories—including the Ryukyus—would be subject to future decisions by the Allied powers.

After the war, the Nationalist government of China recognized the strategic value of the Ryukyu Islands and proposed a joint trusteeship with the United States for a period of five to ten years. Later proposals included allowing the U.S. to establish bases on some islands, indicating a willingness to compromise and an understanding that the U.S. would not readily transfer sovereignty to China. Chinese domestic opinion was divided: some called for an independent Ryukyuan state, others demanded the full incorporation of the Ryukyus into Chinese territory. Most emphasized the islands' strategic importance as a buffer zone and argued they should not fall into the hands of another power.

In 1946, the United States Department of State advocated for the return of the Ryukyus to Japan, citing anti-expansion principles and concerns over economic burdens. In contrast, the U.S. military proposed that the islands be designated as a "strategic trust territory," with Okinawa Island declared a "strategic area." Military leaders argued that the high cost of American lives during the Battle of Okinawa justified permanent military governance as compensation for their sacrifice. After internal debate, the plan was formalized in SWNCC 59 / 1, which proposed placing Okinawa under U.S. military administration rather than returning it to Japan, using trusteeship arrangements to sidestep sovereignty issues. The directives SCAPIN-677 and SCAPIN-841 established the legal and administrative basis for U.S. jurisdiction south of the 29th parallel north, forming the framework for postwar American control.

U.S. administration (1945–1972)

On April 1, 1945, the U.S. Army and Marine Corps launched an invasion of Okinawa with approximately 185,000 troops. They encountered determined and intense resistance from the Japanese defenders, but the U.S. emerged victorious on June 22. During the fighting, approximately one-third of Okinawa's civilian population lost their lives. The dead, of all nationalities, are commemorated at the Cornerstone of Peace.

During the battle of Okinawa, U.S. fleet admiral Chester Nimitz had issued an order on 5 April 1945, declaring the suspension of the Japanese administration in Okinawa and the establishment of the United States Military Government of the Ryukyu Islands (USMGR). The United States Civil Administration of the Ryukyu Islands was later established in 1950 to replace the USMGR, and the U.S. administration of Okinawa was later formalized in 1952, when the Treaty of San Francisco came into effect.

During the Korean War, B-29 Superfortresses flew bombing missions over Korea from Kadena Air Base on Okinawa. The military buildup on the island during the Cold War increased a division between local inhabitants and the American military. Under the 1952 Treaty of Mutual Cooperation and Security between the United States and Japan, United States Forces Japan (USFJ) have maintained a large military presence.

During the mid-1950s, the U.S. seized land from Okinawans to build new bases or expand currently existing ones. According to the Melvin Price Report, by 1955, the military had displaced 250,000 residents.

Since 1960, the U.S. and Japan have maintained an agreement that allows the U.S. to secretly bring nuclear weapons into Japanese ports. The Japanese people tended to oppose the introduction of nuclear arms into Japanese territory; the Japanese government's assertion of Japan's non-nuclear policy and a statement of the Three Non-Nuclear Principles reflected this popular opposition. Most of the weapons were alleged to be stored in ammunition bunkers at Kadena Air Base. Between 1954 and 1972, 19 different types of nuclear weapons were deployed in Okinawa, but with fewer than around 1,000 warheads at any one time. In fall 1960, U.S. commandos in Green Light Teams secret training missions carried small nuclear weapons on the east coast of Okinawa Island.

Post-reversion history (1972–present)

The U.S. Marine Corps buried a massive stockpile of Agent Orange at the Futenma air station in Okinawa, seriously sickening the base's former head of maintenance and potentially contaminating nearby residents and the ground beneath the base. The barrels were abandoned in Okinawa at the end of the Vietnam War – when the U.S. government banned the dioxin-laden defoliant for health reasons — and were buried at the installation in the city of Ginowan after the Pentagon ignored repeated requests to safely dispose of them, according to the veterans who served at the installation in the 1970s and 1980s. The 1995 kidnaping, beating, and rape of a 12-year-old girl by three U.S. servicemen triggered widespread protests in Okinawa. Reports by the local media of accidents and crimes committed by U.S. servicemen have reduced the local population's support for the U.S. military bases. A strong emotional response has emerged from certain incidents.

Documents declassified in 1997 proved that both tactical and strategic weapons have been maintained in Okinawa. In 1999 and 2002, the Japan Times and the Okinawa Times reported speculation that not all weapons were removed from Okinawa. On October 25, 2005, after a decade of negotiations, the governments of the U.S. and Japan officially agreed to move Marine Corps Air Station Futenma from its location in the densely populated city of Ginowan to the more northerly and remote Camp Schwab in Nago by building a heliport with a shorter runway, partly on Camp Schwab land and partly running into the sea. The move is partly an attempt to relieve tensions between the people of Okinawa and the Marine Corps.

Despite Okinawa prefecture constituting only 0.6% of Japan's land surface, in 2006 75% of all USFJ bases were located on Okinawa, occupying 18% of the main island.

In a poll conducted by The Asahi Shimbun in May 2010, 43% of the Okinawan population wanted the complete closure of the U.S. bases, 42% wanted reduction, and 11% wanted to maintain the status quo. Okinawan feelings about the U.S. military are complex.

In early 2008, U.S. Secretary of State Condoleezza Rice apologized after a series of crimes involving American troops in Japan, including the rape of a young girl of 14 by a Marine on Okinawa. The U.S. military imposed a temporary 24-hour curfew on military personnel and their families to ease the anger of local residents. Some cited statistics that the crime rate of military personnel is consistently less than that of the general Okinawan population. However, some criticized the statistics as unreliable, since violence against women is under-reported. Between 1972 and 2009, U.S. servicemen committed 5,634 criminal offenses, including 25 murders, 385 burglaries, 25 arsons, 127 rapes, 306 assaults and 2,827 thefts. Yet, per Marine Corps Installations Pacific data, U.S. service members are convicted of far fewer crimes than local Okinawans.

Geography

Major islands

The islands comprising the prefecture are the southern two thirds of the archipelago of the Ryūkyū Islands (琉球諸島, Ryūkyū-shotō). Okinawa's inhabited islands are typically divided into three geographical archipelagos. From northeast to southwest:

Okinawa Islands (沖縄諸島, Okinawa-shotō)

Iejima (伊江島, Iejima)

Kume-jima (久米島町, Kumejima-chō)

Okinawa Island (沖縄島, Okinawa-jima)

Kerama Islands (慶良間諸島, Kerama-shotō)

Miyako Islands (宮古列島, Miyako-rettō)

Miyako-jima (宮古島, Miyako-jima)

Yaeyama Islands (八重山列島, Yaeyama-rettō)

Iriomote Island (西表島, Iriomote-jima)

Ishigaki Island (石垣島, Ishigaki-jima)

Yonaguni (与那国島, Yonaguni-jima)

Senkaku Islands (尖閣諸島, Senkaku-shotō)

Daitō Islands (大東諸島, Daitō-shotō)

Minamidaitōjima (南大東島, Minami-Daitō)

Kitadaitōjima (北大東島, Kita-Daitō)

Okidaitōjima (沖大東島, Oki-Daitō)

Natural parks

Approximately 36% percent of the total land area of the prefecture was designated as natural parks, namely the Iriomote-Ishigaki, Kerama Shotō, and Yambaru National Parks; Okinawa Kaigan and Okinawa Senseki Quasi-National Parks; and Irabu, Kumejima, Tarama, and Tonaki Prefectural Natural Parks. The natural parks of Okinawa Prefecture were established to protect the region's tropical landscapes, including coastlines, coral reefs, forests, and island ecosystems.

Ecology

The dugong is an endangered marine mammal related to the manatee. Iriomote is home to one of the world's rarest and most endangered cat species, the Iriomote cat. The region is also home to at least one endemic pit viper, Trimeresurus elegans. The islands of Okinawa are surrounded by some of the most abundant coral reefs found in the world. The world's largest colony of rare blue coral is found off Ishigaki Island. The sea turtles return yearly to the southern islands of Okinawa to lay their eggs. The summer months carry warnings to swimmers regarding venomous jellyfish and other dangerous sea creatures.

Okinawa is a major producer of sugar cane, pineapple, papaya, and other tropical fruit, and the Southeast Botanical Gardens represent tropical plant species.

Geology

The island is largely composed of coral, and rainwater filtering through that coral has given the island many caves, which played an important role in the Battle of Okinawa. Gyokusendo is an extensive limestone cave in the southern part of Okinawa's main island. Nuchishinji-gama (Cave Okinawa) served as a place of refuge during the Battle of Okinawa from American troops.

Climate

The island experiences temperatures above 20 °C (68 °F) for most of the year. The climate of the islands ranges from humid subtropical climate (Köppen climate classification Cfa) in the north, such as Okinawa Island, to tropical rainforest climate (Köppen climate classification Af) in the south such as Iriomote Island. Snowfall is unheard of at sea level. However, on January 24, 2016, sleet was reported in Nago for the first time on record.

Politics

Due to its unique historical background, Okinawa has a significantly stronger progressive (left-wing) presence compared to most other Japanese prefectures; this makes it one of the most politically polarized regions in the country. The Okinawa Social Mass Party, a local progressive political party, has played an important role in postwar Okinawan politics.

In 2014, various progressive parties such as the Social Democratic Party, Japanese Communist Party, Democratic Party, and the Okinawa Social Mass Party formed a cross-party electoral alliance with some conservative figures who also opposed the relocation of the U.S. Marine Corps Air Station Futenma to the city of Nago. This movement, known as the "All-Okinawa" campaign, achieved electoral victories in the 2014 Okinawa gubernatorial election, the 2016 Okinawa prefectural election, and others.

Since Japan introduced the Single-member district system in 1996, Okinawa has been divided into four electoral districts for the House of Representatives. Among these, Okinawa's 2nd District, which hosts the highest concentration of U.S. military bases, has long been a stronghold for the progressive camp. Kantoku Teruya of the Social Democratic Party held this seat from 2003 onwards. The other three districts have seen fierce competition between conservatives and progressives, with frequent changes in party control.

In the 2014 Japanese general election, all four Okinawan districts elected candidates opposed to the relocation of the Futenma base to Nago. In the 1st District, Seiken Akamine of the Japanese Communist Party won a seat—marking the JCP's first single-member district victory in Okinawa and its first nationwide in 18 years.

In the 2017 Japanese general election, the Liberal Democratic Party (LDP) won the seat in the 4th District. In the 2021 Japanese general election, LDP candidates won in both the 3rd and 4th Districts and also gained proportional representation seats in the 1st and 2nd Districts. The Japanese Communist Party and the Social Democratic Party each retained one seat. In the 2026 Japanese general election, the LDP won a seat in each of Okinawa's four districts.

In the House of Councillors, Okinawa is represented by two seats in a single at-large district. Both are currently held by politicians who oppose the Futenma base relocation. However, in proportional representation voting, the LDP has consistently received the highest number of votes in Okinawa.

U.S. military bases

While Okinawa comprises only 0.6% of Japan's land area, it hosts approximately 74% of all U.S. military facilities in the country. The 33 American bases in Okinawa occupy around 10% of the prefecture's land—up to 18% on Okinawa Island. Approximately 47,300 U.S. military personnel and their families reside in the prefecture.

Among the many military issues, the relocation of Marine Corps Air Station Futenma has been the most contentious. Due to its proximity to residential areas and repeated accidents, Futenma has been labeled one of the most dangerous military bases in the world. The prefectural government has long called for its relocation outside of Okinawa. In 2010, Japan and the U.S. agreed to relocate the base to Camp Schwab in Nago, sparking widespread protests.

Another key issue is crime involving U.S. military personnel. Between the 1972 reversion and 2015, 5,896 criminal cases involving U.S. forces were reported in Okinawa. In 2016, a high-profile rape and murder case involving a U.S. military contractor in Uruma triggered mass protests.

On the other hand, U.S. bases are Okinawa's second-largest source of employment.

According to a 2017 NHK survey, 25.7% of Okinawans wanted the complete removal of U.S. military bases, while 50.6% preferred reducing their presence to levels comparable to mainland Japan. Only 26.5% supported relocating Futenma to Nago, while 62.6% were opposed.

On February 24, 2019, a prefectural referendum was held on land reclamation in Henoko for the new U.S. base. With a turnout of 52.48%, 71.74% opposed the project, 18.99% supported it, and 8.70% expressed no clear opinion.

Independence movement

After Japan annexed the Ryukyu Kingdom in 1879 during the so-called Ryukyu Disposition, the last king, Shō Tai, was relocated to Tokyo. In the following years, Ryukyuan figures who opposed the new arrangements petitioned the Qing dynasty for redress, organizing in treaty-port communities such as Fuzhou, Beijing, and Tianjin. Contemporary sources referred to some émigrés as dasshinnin (脱清人), who advocated Qing intervention to restore Ryukyuan autonomy or statehood. Diplomatic mediation was even sought from former U.S. President Ulysses S. Grant in 1879–1880, but negotiations ultimately failed to produce a settlement; the issue receded after the First Sino-Japanese War.

Following World War II, the Ryukyu Islands were placed under U.S. administration (1945–1972). During this period, proposals ranging from restoration of Ryukyuan statehood to enhanced local self-government were debated among Okinawan actors and in Japanese civil society. Under the 1971 Okinawa Reversion Agreement, administrative rights returned to Japan in 1972 while U.S. bases remained under the Treaty of Mutual Cooperation and Security between the United States and Japan.

In contemporary politics, independence advocacy persists alongside broader autonomy movements and base-related activism. Polling generally shows limited support for full independence but greater backing for stronger local autonomy; for example, a 2022 Okinawa Times survey reported 3% support for independence, 48% for a "strongly empowered" local government, and 42% for maintaining the status quo. Public debate has increasingly extended to digital platforms; Japanese media and academic outlets have reported instances of inauthentic social-media activity linked to foreign information operations concerning Okinawa and independence narratives.

These are the towns and villages in each district:

Demographics

Ethnic groups

The indigenous Ryukyuans make up the majority of Okinawa Prefecture's population and are also the main ethnic group of the Amami Islands to the north. Large Okinawan diaspora communities persist in places such as South America and Hawaii. With the introduction of American military bases, there are an increasing number of half-American children in Okinawa, including prefecture governor Denny Tamaki. The prefecture also has a sizable minority of Yamato people from mainland Japan; exact population numbers are difficult to establish, as the Japanese government does not officially recognize Ryukyuans as a distinct ethnic group from Yamatos.

The overall ethnic identity of Okinawa residents is rather split. According to a telephone poll conducted by Lim John Chuan-tiong (林泉忠), an associate professor with the University of the Ryukyus, 40.6% of respondents identified as "沖縄人 (Okinawan)", 21.3% identified as "日本人 (Japanese)" and 36.5% identified as both.

Population

Per Japanese census data, Okinawa prefecture has had continuous positive population growth since 1960. However, in the 21st century, growth has slowed, with a decline expected to begin by 2030 as East Asia's population ages quickly. The 2025 Census recorded Okinawa's population as 1,468,220, a modest increase of 740 from 2020.

Language

There remain six Ryukyuan languages, which, although part of the same Japonic language family, are mutually unintelligible with Japanese. One of the Ryukyuan languages is spoken in Kagoshima Prefecture, rather than in Okinawa Prefecture. These languages are in decline as the younger generation of Okinawans uses Standard Japanese. Mainland Japanese and some Okinawans generally perceive the Ryukyuan languages as dialects. Standard Japanese is almost always used in formal situations. In informal situations, the everyday language among Okinawans under the age of 60 is Okinawan Japanese, which is often mistaken by non-Okinawans as the Okinawan language proper. The actual traditional Okinawan language is still used in traditional cultural activities, such as folk music and folk dance. There is a radio-news program in the language as well.

Culture

Okinawan culture retains strong influences from its historical trading partners. Among these, Kyushu has maintained the closest economic and cultural ties with Okinawa from ancient times to the present, and the two regions share many cultural traits. Elements of Okinawan culture can be found throughout Kyushu, and vice versa. For instance, Okinawan musical scales appear in Kyushu's folk songs, and there are notable similarities in cuisine and language. Kyushu is also home to a traditional instrument called the gottan(ゴッタン), which closely resembles the Okinawan sanshin (三線).

Furthermore, the customs of the Okinawan islands show strong influences from China, Thailand, and Austronesian-speaking regions.

One of the most famous cultural traditions of Okinawa is undoubtedly karate. Karate is a martial art that originated when Chinese kung fu was introduced to the Ryukyu Kingdom and then developed independently within the islands before being brought to mainland Japan. Today, karate is practiced around the world in various styles, including Shotokan, Goju-ryu, Shito-ryu, and Uechi-ryu.

A cultural feature of the Okinawans is the forming of moais. A moai is a community social gathering and groups that come together to provide financial and emotional support through emotional bonding, advice giving, and social funding. This provides a sense of security for the community members and as mentioned in the Blue Zone studies, may have been a contributing factor to the longevity of its people. However, in recent decades Okinawans' life expectancy has fallen significantly (also bringing into question the general validity of the 'Blue Zones' denomination), which often has been blamed on cultural influence from the rest of Japan, as well as foreign influences on Okinawans' lifestyle.

Two Okinawan writers have received the Akutagawa Prize: Eiki Matayoshi in 1995 for The Pig's Retribution (豚の報い, Buta no mukui) and Shun Medoruma in 1997 for A Drop of Water (Suiteki). The prize was also won by Okinawans in 1967 by Tatsuhiro Oshiro for Cocktail Party (Kakuteru Pāti) and in 1971 by Mineo Higashi for Okinawan Boy (Okinawa no Shōnen).

A traditional craft, the fabric named bingata, is made in workshops on the main island and elsewhere.

Music

The music of the prefecture contains native and imported influences in both koten (classical) and min'yō (folk) styles. Okinawan instruments include the sanshin—a three-stringed banjo-like instrument, closely related to the Chinese sanxian, and ancestor of the Japanese shamisen. Its body is often bound with snakeskin (from pythons, imported from elsewhere in Asia, rather than from Okinawa's venomous habu, which are too small for this purpose). Okinawan musical cultures integrate dance with music, such as in eisa, a traditional drumming dance.

Religion

Okinawan people have inherited a traditional religious belief system known as Ryukyuan Shinto, which is similar to but distinct from modern Japanese Shinto. This indigenous belief system is animistic in nature, characterized by ancestor worship and a deep respect for the relationships between the living, the dead, and the gods or spirits of the natural world.

Shamanic practitioners, known as Yuta, continue to play an active role in Okinawan society. They perform ritual prayers, divination, spiritual consultations, and even communicate with the spirits of the deceased. For many people, yuta serve as important spiritual guides who offer advice and solutions to both supernatural and everyday life problems.

Throughout Okinawa, there are sacred sites known as utaki, where rituals and ceremonies are performed. Ryukyuan beliefs preserve many elements of ancient Japanese spirituality—such as those from the Jōmon and Yayoi periods—which have largely disappeared on the Japanese mainland. As such, they are considered important resources in comparative mythology and religious studies.

Cuisine and diet

The Okinawan diet consists of low-fat, low-salt foods, such as whole fruits and vegetables, legumes, tofu, and seaweed. Okinawans are particularly well known for consuming purple potatoes, also known as Okinawan sweet potatoes. Okinawans used to be known for their longevity compared to the rest of Japan and the world in general. This particular island is a so-called Blue Zone, an area where people are purported to live longer than most others elsewhere in the world. Possible explanations for this were diet, low-stress lifestyle, caring community, activity, and spirituality of the inhabitants of the island.

A traditional Okinawan product that owes its existence to Okinawa's trading history is awamori—an Okinawan distilled spirit made from indica rice imported from Thailand.

Architecture

Despite widespread destruction during World War II, there are many remains of a unique type of castle or fortress known as gusuku; the most significant are inscribed on the UNESCO World Heritage List (Gusuku Sites and Related Properties of the Kingdom of Ryukyu). In addition, twenty-three Ryukyuan architectural complexes and forty historic sites have been designated for protection by the national government. Shuri Castle in Naha is a UNESCO World Heritage Site.

Whereas most homes in Japan are made from wood and allow free-flow of air to combat humidity, typical modern homes in Okinawa are made from concrete with barred windows to protect from flying plant debris and to withstand regular typhoons. Roofs are designed with strong winds in mind, in which each tile is cemented on and not merely layered as seen with many homes in Japan. The Nakamura House (中村家住宅 (沖縄県)) is an original 18th century farmhouse in Kitanakagusuki. Many roofs also display a lion-dog statue, called a shisa, which is said to protect the home from danger. Roofs are typically red in color and are inspired by Chinese design.

Education

The public schools in Okinawa are overseen by the Okinawa Prefectural Board of Education. The agency directly operates several public high schools including Okinawa Shogaku High School. The U.S. Department of Defense Dependents Schools operates 13 schools total in Okinawa. Seven of these schools are located on Kadena Air Base.

Okinawa has many types of private schools. Some of them are cram schools, also known as juku. Others, such as Nova, solely teach language. There are 10 colleges / universities in Okinawa, including the University of the Ryukyus, the only national university in the prefecture, and the Okinawa Institute of Science and Technology, a new international research institute. Okinawa's American military bases also host the Asian Division of the University of Maryland University College.

Sports

Martial arts

Martial arts, such as tegumi and Okinawan kobudō originated among the indigenous people of Okinawa Island. Due to its central location, Okinawa was influenced by various cultures including Japan, China and Southeast Asia in its martial arts culture.

Karate originated in the Ryukyu Kingdom, under Chinese influence. Over time, it developed into several styles and sub-styles. On Okinawa, the three main styles are considered to be Shōrin-ryū, Gōjū-ryū and Uechi-ryū. Internationally, the various styles and sub-styles include Matsubayashi-ryū, Wadō-ryū, Isshin-ryū, Shōrinkan, Shotokan, Shitō-ryū, Shōrinjiryū Kenkōkan, Shorinjiryu Koshinkai, and Shōrinji-ryū.

Following Okinawa's occupation, karate spread to the United States and the rest of the world. It is now popular across the world, and has since been included in the Olympic Games.

Association football

FC Ryukyu is a professional football team based on Okinawa. Since 2014 they have competed in the second or third tier in the national league system.

Basketball

The Ryukyu Golden Kings are a professional basketball team that compete in the B.League, the top-tier professional basketball league of Japan. They are successful, having won the national title five times (most recently in 2023).

The Okinawa Arena has hosted the Japanese men's basketball team for various 2023 FIBA Basketball World Cup Asian qualifiers. It was also one of five venues to host the 2023 FIBA Basketball World Cup, the other four were in the Philippines and Indonesia.

Harii

Harii (ハーリー) is a traditional rowing sport practiced mainly in Kyushu and Okinawa, Japan.

It is typically held during events such as the Kaijin-sai (海神祭) around the 4th day of the 5th month of the lunar calendar (ユッカヌヒー), or near the lunar Obon season.

The sport features a boat race in which dozens of men board a harii boat and row competitively; the team that reaches the finish line first is declared the winner.

Various harii races are held throughout Okinawa, with the most prominent being the Naha Harii in the city of Naha.

Handball

Ryukyu Corazon (Naha)

Baseball

In 2019, BASE Okinawa Baseball Club attempted forming the first-ever professional baseball team on Okinawa, the Ryukyu Blue Oceans. The team was expected to be fully organized by January 2020 with a view to joining the Nippon Professional Baseball league.

However, complications arising from the COVID-19 pandemic compounded with allegations of financial mismanagement – including reports of unpaid wages to players – resulted in the project being put on hold in November 2022. An exodus of players and staff followed, resulting in management company BASE officially filing for bankruptcy on April 6, 2023.

Despite the lack of a local team, various professional baseball teams hold winter training camps in Okinawa as it is the warmest prefecture of Japan, with no snow and higher average temperatures than other prefectures. In 2025, ten teams held such camps across the prefecture, including two teams from the KBO League.

Economy

The island economy is primarily driven by tourism and the U.S. military presence. Other significant contributors to the economy include public utilities and public works, as well as, to a lesser extent, limestone mining, cement production, agriculture, telecommunications (Okinawa Cellular Telephone), and alcoholic beverage production (Orion Breweries).

The 34 U.S. military installations on Okinawa are financially supported by the U.S. and Japan. The bases provide jobs for Okinawans, both directly and indirectly; in 2011, the U.S. military employed over 9,800 Japanese workers in Okinawa. As of 2012 the bases accounted for up to 5% of the economy. However, Koji Taira argued in 1997 that because the U.S. bases occupy around 20% of Okinawa's land, they impose a deadweight loss of 15% on the Okinawan economy. The Tokyo government also pays the prefectural government around ¥10 billion per year in compensation for the American presence, including, for instance, rent paid by the Japanese government to the Okinawans on whose land American bases are situated. A 2005 report by the U.S. Forces Japan Okinawa Area Field Office estimated that in 2003 the combined U.S. and Japanese base-related spending contributed $1.9 billion to the local economy. On January 13, 2015, in response to the citizens electing governor Takeshi Onaga, the national government announced that Okinawa's funding will be cut, due to the governor's stance on removing the US military bases from Okinawa, which the national government does not want happening.

The Okinawa Convention and Visitors Bureau is exploring the possibility of using facilities on the military bases for large-scale meetings, conferencing, exhibitions events.
