Okinawan language in the context of Utaki

Okinawa Island (Japanese: 沖縄島, Hepburn: Okinawa-jima; Okinawan: 沖縄 / うちなー, romanized: Uchinā; Kunigami: ふちなー, romanized: Fuchináa), also known as Okinawa Main Island (沖縄本島, Okinawa-hontō), is the largest of the Okinawa Islands and the Ryukyu (Nansei) Islands of Japan in the Kyushu region. It is the smallest and least populated of the five main islands of Japan. The island is approximately 106 kilometres (66 mi) long, an average 11 kilometres (7 mi) wide, and has an area of 1,206.98 square kilometers (466.02 sq mi). It is roughly 640 kilometres (350 nmi; 400 mi) south of the main island of Kyushu and the rest of Japan. It is 500 km (270 nmi; 310 mi) northeast of Taiwan. The total population of Okinawa Island was 1,384,762 in 2009. The greater Naha area has roughly 800,000 residents, while the city itself has about 320,000 people. Naha is the seat of Okinawa Prefecture on the southwestern part of Okinawa Island. Okinawa has a humid subtropical climate.

Okinawa has been a strategic location for the United States Armed Forces since the Battle of Okinawa and the end of World War II. The island was formally controlled by the United States Civil Administration of the Ryukyu Islands until 1972, with around 26,000 U.S. military personnel stationed on Okinawa today, comprising about half of the total complement of the United States Forces Japan, spread among 31 areas, across 13 bases and 48 training sites. United States military installations cover approximately 25% of the island and have been a point of contention among locals. Crimes committed by US military personnel, notably the 1995 Okinawa rape incident, have caused protests against the US military presence in Okinawa.

Okinawa Prefecture (Japanese: 沖縄県, Hepburn: Okinawa-ken; pronounced [o.kʲi.na.wa(ꜜ.keɴ)]; Okinawan: 沖縄県, romanized: Uchinaachin) is the southernmost and westernmost prefecture of Japan. It consists of three main island groups—the Okinawa Islands, the Sakishima Islands, and the Daitō Islands—spread across a maritime zone approximately 1,000 kilometers east to west and 400 kilometers north to south. Despite a modest land area of 2,281 km (880 sq mi), Okinawa's territorial extent over surrounding seas makes its total area nearly half the combined size of Honshu, Shikoku, and Kyushu. Of its 160 islands, 49 are inhabited. The largest and most populous island is Okinawa Island, which hosts the capital city, Naha, as well as major urban centers such as Okinawa, Uruma, and Urasoe. The prefecture has a subtropical climate, characterized by warm temperatures and high rainfall throughout the year. People from the Nansei Islands, including Okinawa, the Sakishima Islands, and parts of Kagoshima Prefecture, are often collectively referred to as Ryukyuans. However, there are significant cultural and customary differences between individual islands and even between local communities.

Historically the center of the Ryukyu Kingdom, Okinawa long served as a maritime trading hub and cultural gateway; the kingdom participated in the Chinese tributary system—maintaining formal tribute relations with the Ming and Qing—and retained distinct statehood until it was incorporated into Japan as Okinawa Prefecture in 1879 following the Ryukyu Disposition. After the Battle of Okinawa (1945), the islands were under U.S. administration until reversion to Japan in 1972, and today host a large share of U.S. military facilities in Japan (around 70% by area of land exclusively used by U.S. forces), a continuing source of local and national debate. A small but persistent independence movement exists, reflecting Okinawa's distinct historical trajectory and identity.

Kana (仮名; Japanese pronunciation: [ka.na]) are syllabaries used to write Japanese phonological units, morae. In current usage, kana most commonly refers to hiragana and katakana. It can also refer to their ancestor magana (真仮名; lit. 'true kana'), which were Chinese characters used phonetically to transcribe Japanese (e.g. man'yōgana); and hentaigana, which are historical variants of the now-standard hiragana.

Katakana, with a few additions, are also used to write Ainu. A number of systems exist to write the Ryūkyūan languages, in particular Okinawan, in hiragana. Taiwanese kana were used in Taiwanese Hokkien as ruby text for Chinese characters in Taiwan when it was under Japanese rule.

Naha (Japanese: 那覇市, Hepburn: Naha-shi; Japanese: [naꜜ.ha, na.haꜜ.ɕi]; Okinawan: Naafa or Nafa) is the capital city of Okinawa Prefecture, the southernmost prefecture of Japan. As of 1 June 2019, the city has an estimated population of 317,405 and a population density of 7,939 people per km (20,562 persons per sq. mi.). The total area is 39.98 km (15.44 sq mi).

Naha is located on the East China Sea coast of the southern part of Okinawa Island, the largest of Okinawa Prefecture. The modern city was officially founded on May 20, 1921. Before that, Naha had been for centuries one of the most important and populous sites in Okinawa.

The Miyako Islands (宮古列島, Miyako-rettō; Miyako: Myaaku, Tarama dialect: Meeku, Okinawan: Naaku, Northern Ryukyuan: みやこ Miyako) (also Miyako Jima group) are a group of islands in Okinawa Prefecture, Japan, belonging to the Ryukyu Islands. They are situated between Okinawa Island and the Yaeyama Islands.

In the early 1870s, the population of the islands was estimated to number approximately 10,000. Miyako Island has 55,914 people. A bridge connects Miyako Island to Ikema Island, which has 801 people. Tarama village has 1,214 people, between the two islands of Minna and Tarama.

The Yaeyama Islands (八重山列島 Yaeyama-rettō, also 八重山諸島 Yaeyama-shotō, Yaeyama: Yaima, Yonaguni: Daama, Okinawan: Yeema, Northern Ryukyuan: やへま Yapema) are an archipelago in the southwest of Okinawa Prefecture, Japan, and cover 591.46 square kilometres (228.36 sq mi). The islands are located southwest of the Miyako Islands, part of the Ryukyu Islands archipelago. The Yaeyama Islands are the most remote part of Japan from the main islands and contain Japan's southernmost (Hateruma) and westernmost (Yonaguni) inhabited islands. The city of Ishigaki serves as the political, cultural, and economic center of the Yaeyama Islands. On maps dating to the 1700s, the Yaeyama Group of Islands appears as the "Majico Sima Group", "Nambu-soto Islands", "Nambu Soto", and the "Taipin Islands".

The Sakishima Islands (Japanese: 先島諸島 / 先島群島, Hepburn: Sakishima-shotō / Sakishima-guntō; Okinawan: Sachishima; Miyako: Saksїzїma; Yaeyama: Sakїzїma; Yonaguni: Satichima) are an archipelago located at the southernmost end of the Japanese Archipelago. They are part of the Ryukyu Islands and include the Miyako Islands and the Yaeyama Islands. The islands are administered as part of Okinawa Prefecture, Japan.

Yonaguni (Japanese: 与那国島, Hepburn: Yonaguni-jima; Yonaguni: Dunan-chima, older Juni-shima; Yaeyama: Yunoon-zïma; Okinawan: Yunaguni-jima), one of the Yaeyama Islands, is the westernmost island of Japan, lying between the East China Sea and the Philippine Sea. A mere 107.4 kilometers (58.0 nmi; 66.7 mi) separate the island from Taiwan at their closest points. It is administered as the town of Yonaguni, Yaeyama Gun, Okinawa, and there are three settlements: Sonai, Kubura, and Higawa. There have been discussions to establish direct ferry services with Taiwan in order to bolster tourism.

The Ryukyu Disposition (琉球処分, Ryūkyū shobun; Okinawan:Ruucuu-sjubn), also called the Ryukyu Annexation (琉球併合, Ryūkyū heigō) or the annexation of Okinawa, was the political process during the early years of the Meiji period that saw the incorporation of the former Ryukyu Kingdom into the Empire of Japan as Okinawa Prefecture (i.e., one of Japan's "home" prefectures) and its decoupling from the Chinese tributary system. These processes began with the creation of the Ryukyu Domain in 1872 and culminated in the kingdom's annexation and final dissolution in 1879; immediate diplomatic fallout and consequent negotiations with Qing China, brokered by Ulysses S. Grant, effectively came to an end late the following year. The term is also sometimes used more narrowly in relation to the events and changes of 1879 alone. The Ryūkyū Disposition has been "alternatively characterized as aggression, annexation, national unification, or internal reform".

Karate (空手) (/kəˈrɑːti/; Japanese pronunciation: [kaɾate] ; Okinawan pronunciation: [kaɾati]), also karate-do (空手道, Karate-dō), is a martial art developed in the Ryukyu Kingdom. It developed from the indigenous Ryukyuan martial arts (called te (手), "hand"; tī in Okinawan) under the influence of Chinese martial arts. While modern karate is primarily a striking art that uses punches and kicks, traditional karate training also employs throwing and joint locking techniques. A karate practitioner is called a karate-ka (空手家).

Beginning in the 1300s, early Chinese martial artists brought their techniques to Okinawa. Despite the Ryukyu Kingdom being turned into a puppet state by Japanese samurai in 1609, after the Invasion of Ryukyu, its cultural ties to China remained strong. Since Ryukyuans were banned from carrying swords under samurai rule, groups of young aristocrats created unarmed combat methods as a form of resistance, combining Chinese and local styles of martial arts. Training emphasized self-discipline. This blend of martial arts became known as kara-te 唐手, which translates to "Chinese hand." Initially, there were no uniforms, colored belts, ranking systems, or standardized styles. Many elements essential to modern karate were actually incorporated a century ago.

Okinawan is a Japonic language spoken on Okinawa Island. Okinawan-language documents of the Ryukyu Kingdom were written in kanji and hiragana, derived from Japan.

Although generally agreed among linguists to be a distinct language, most Japanese, as well as some Okinawans, tend to think of Okinawan as merely a regional dialect of Japanese, even though it is not mutually intelligible to monolingual Japanese speakers. Modern Okinawan is not written frequently.

Kin (Japanese: 金武町, Hepburn: Kin-chō; Kunigami and Okinawan: Chin) is a town located in Kunigami District, Okinawa Prefecture, Japan.

In 1 October 2020, the town had an estimated population of 10,806 and a density of 290 persons per km. The total area of Kin is 37.57 square kilometres (14.51 sq mi). 59% of the land area of Kin remains under control of the United States military, the highest percentage of any municipality in Okinawa Prefecture. The population of the town is concentrated on a strip of land on the coast of Kin Bay. Kin is home to Camp Hansen, a military base of the United States Marines, as well as other smaller military installations.

Okinawan Japanese (ウチナーヤマトゥグチ, 沖縄大和口, Uchinaa Yamatu-guchi) is the Japanese language as spoken by the people of Okinawa Islands. The name Uchinaa Yamatu-guchi is composed of Uchinaa meaning "Okinawa", Yamatu referring to mainland Japan, and the suffix -guchi approximately meaning "language". Okinawan Japanese's pronunciation and words are influenced by the Northern Ryukyuan Okinawan and Kunigami languages spoken on the islands. However, the amount of influence Ryukyuan has on the Japanese spoken by Okinawans varies by family and age, as well as by region. Because of the many US military bases found in Okinawa, Okinawan Japanese has incorporated some English loanwords. Okinawan Japanese is a Japanese dialect (方言), unlike the Okinawan and Kunigami languages. Standard Japanese is used in formal settings while Ryukyuan languages and Okinawan Japanese are used in informal settings.

Shuri (首里; Okinawan: スイ Sui or Shui, Northern Ryukyuan: しより Shiyori) is a district of the city of Naha, Okinawa, Japan. Formerly a separate city in and of itself, it was once the royal capital of the Ryūkyū Kingdom, hence the name. A number of famous historical sites are located in Shuri, including Shuri Castle, the Shureimon gate, Sunuhyan-utaki (a sacred space of the native Ryukyuan religion), and royal mausoleum Tamaudun, all of which are designated World Heritage Sites by UNESCO.

Originally established as a castle town surrounding the royal palace, Shuri ceased to be the capital when the kingdom was annexed and incorporated into Japan as Okinawa prefecture. In 1896, Shuri was made a ward (区, ku) of the new prefectural capital, Naha, though it was made a separate city again in 1921. In 1954, it was merged again into Naha.
