Okinawa Prefecture in the context of "List of regions of Japan"

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.

The Ryukyu Islands (Japanese: 琉球列島, Hepburn: Ryūkyū Rettō), also known as the Nansei Islands (南西諸島, Nansei Shotō; lit. 'Southwest Islands') or the Ryukyu Arc (琉球弧, Ryūkyū-ko), are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ryukyu Islands are divided into the Satsunan Islands (Ōsumi, Tokara and Amami) and Okinawa Prefecture (Daitō, Miyako, Yaeyama, Senkaku, Okinawa, Sakishima Islands (further divided into the Miyako and Yaeyama Islands), and Yonaguni as the westernmost). The larger ones are mostly volcanic islands and the smaller mostly coral. The largest is Okinawa Island.

The climate of the islands ranges from humid subtropical climate (Köppen climate classification Cfa) in the north to tropical rainforest climate (Köppen climate classification Af) in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs.

The Daitō Islands (Japanese: 大東諸島, Hepburn: Daitō-shotō) are an archipelago consisting of three isolated coral islands, administered by Japan, in the Philippine Sea southeast of Okinawa. The islands have a total area of 44.427 square kilometers (17.153 sq mi) and a population of 2,107.

Administratively, the whole group belongs to Shimajiri District of Okinawa Prefecture, and is divided between the villages of Minamidaitō and Kitadaitō, with uninhabited Okidaitōjima island administered as part of Kitadaitō municipality, although physically located closer to Minamidaitōjima.

The Ryukyuans are a Japonic-speaking East Asian ethnic group indigenous to the Ryukyu Islands, which stretch from the island of Kyushu to the island of Taiwan. In Japan, most Ryukyuans live in the Okinawa Prefecture or Kagoshima Prefecture. They speak the Ryukyuan languages, one of the branches of the Japonic language family along with the Japanese language and its dialects.

The United Nations Human Rights Committee in 2008 recommended that Japan, "should expressly recognize the Ainu and Ryukyu/Okinawa as indigenous peoples in domestic legislation, adopt special measures to protect, preserve, and promote their cultural heritage and traditional way of life, and recognize their land rights." The Japanese government has not accepted this recommendation because recognizing, "the Ryukyuan as Indigenous Peoples [would require Japan] to adhere to international law, thus prohibiting military bases on [Ryukyuan] land."

The Ryukyu Kingdom was a kingdom in the Ryukyu Islands from 1429 to 1872. It was ruled as a tributary state of the Ming dynasty by the Ryukyuan monarchy, who unified Okinawa Island to end the Sanzan period, and subsequently extended the kingdom to the Amami Islands and Sakishima Islands. The Ryukyu Kingdom played a central role in the maritime trade networks of medieval East Asia and Southeast Asia despite its small size. The Ryukyu Kingdom became a vassal state of the Satsuma Domain of Japan after the invasion of Ryukyu in 1609 but retained de jure independence until it was transformed into the Ryukyu Domain by the Empire of Japan in 1872. The Ryukyu Domain was formally annexed by Japan in 1879 and reorganized as Okinawa Prefecture, and the Ryukyuan monarchy was integrated into the new Japanese nobility.

The small group of Hachijō dialects (八丈方言, Hachijō hōgen), natively called Shima Kotoba (島言葉; [ɕima kotoba], "island speech"), are, depending on classification, either the most divergent form of Japanese, or comprise a branch of Japonic languages (alongside mainland Japanese, Northern Ryukyuan, and Southern Ryukyuan). Hachijō is currently spoken on two of the Izu Islands south of Tokyo (Hachijō-jima and the smaller Aogashima) as well as on the Daitō Islands of Okinawa Prefecture, which were settled from Hachijō-jima in the Meiji period. It was also previously spoken on the island of Hachijō-kojima, which is now abandoned. Based on the criterion of mutual intelligibility, Hachijō may be considered a distinct Japonic language, rather than a dialect of Japanese.

Hachijō is a descendant of Eastern Old Japanese, retaining several unique grammatical and phonetic features recorded in the Azuma-dialect poems of the 8th-century Man'yōshū and the Fudoki of Hitachi Province. Hachijō also has lexical similarities with the dialects of Kyushu and even the Ryukyuan languages; it is not clear if these indicate that the southern Izu islands were settled from that region, if they are loans brought by sailors traveling among the southern islands, or if they might be independent retentions from Old Japanese.

Eisaku Satō (佐藤 栄作, Satō Eisaku; 27 March 1901 – 3 June 1975) was a Japanese politician who served as prime minister of Japan from 1964 to 1972. He was the third longest-serving and second longest-uninterrupted–serving Japanese prime minister. Satō is best remembered for securing the return of Okinawa in 1972, and for winning the Nobel Peace Prize in 1974, which stirred controversy. He was a former elite bureaucrat like his elder brother Nobusuke Kishi and a member of the Yoshida school like Hayato Ikeda.

Born in Yamaguchi Prefecture, Satō was a member of the Satō–Kishi–Abe family and the younger brother of prime minister Nobusuke Kishi. Satō graduated from Tokyo Imperial University in 1924 and joined the Ministry of Railways. After the war, he entered the National Diet in 1949 as a member of the Liberal Party, and served in a series of cabinet positions under Shigeru Yoshida, including posts and telecommunications minister from 1951 to 1952, construction minister from 1952 to 1953, and chief cabinet secretary from 1953 to 1954. Satō later joined the Liberal Democratic Party and became finance minister from 1958 to 1960 under Nobusuke Kishi and international trade and industry minister from 1961 to 1962 under Hayato Ikeda.

The Okinawa Islands (Japanese: 沖縄諸島 / 沖縄群島, Hepburn: Okinawa Shotō / Okinawa Guntō) are an island group in Okinawa Prefecture, Japan, and are the principal island group of the prefecture. The Okinawa Islands are part of the larger Ryukyu Islands group and are located between the Amami Islands of Kagoshima Prefecture to the northeast and the Sakishima Islands of Okinawa Prefecture to the southwest.

The Okinawa Islands, apart from the main island, contain three smaller island groups: the Kerama, Yokatsu and Iheya-Izena [ja; de] island groups.
