In the 14th century, three separate Okinawan political polities merged into the Ryukyu Kingdom (1429–1872), which continued the maritime trade and tributary relations started in 1372 with Ming China.
[9] In 1879, the Ryukyu Domain was abolished, and the territory was reorganized as Okinawa Prefecture, with the last king (Shō Tai) forcibly exiled to Tokyo.
Since the end of World War II, Ryukyuans have expressed strong resentment against the Japanese government and against U.S. military facilities stationed in Okinawa.
[citation needed] According to the recent genetic studies, the Ryukyuans share more alleles with the southern Jōmon (16,000–3,000 years ago) hunter-gatherers than the Yayoi people, who had rice farming culture, have smaller genetic contributions from Asian continental populations, which supports the dual-structure model of K. Hanihara (1991), a widely accepted theory which suggests that the Yamato Japanese are more admixed with Asian agricultural continental people (from the Korean Peninsula) than the Ainu and the Ryukyuans, with major admixture occurring in and after the Yayoi period (3,000–1,700 years ago).
[41][42] It is assumed that M7a represents "Jomon genotype" introduced by a Paleolithic ancestor from Southeast Asia or the southern region of the Asian continent, around the Last Glacial Maximum with the Ryukyu Islands as one of the probable origin spots; in contrast, the frequency of the D4 haplogroup is relatively high in East Asian populations, including in Japan, indicating immigrant Yayoi people, probably by the end of the late Kaizuka period, while haplogroup B4 presumably ancient aboriginal Taiwanese ancestry.
After the demise of the multi-ethnic Empire of Japan in 1945, successive governments had forged a single Japanese identity by advocating monoculturalism and denying the existence of ethnic minority groups.
[58] There is a lack of evidence that the missions by the Han dynasty (206 BCE–220 CE) reached the islands; however, as the Japanese did reach Han's capital, notes from 57 CE do mention a general practice of tattooing among the people of "hundred kingdoms" in the eastern islands, a practice which was widespread and survived only among the Okinawan's women, Ainu in Hokkaido, and Atayal people in Taiwan.
[58] Cao Wei (220–265) and Han dynasty records show that the inhabitants of western and southern Japan and Okinawa had a lot in common regarding political-social institutions until the 2nd century CE – they were of small stature, bred oxen and swine, and were ruled by women, with a special influence of women sorceresses, related to the Ryukyuan Noro priestesses which were closely associated with local political power until the 20th century, as well as with the Ryukyuan swine economy culture until World War II.
It is suggested that the mention of a specific sorceress Pimeku, her death and successive conflict, is related to some socio-political challenges of the ancient matriarchal system.
According to the Shoku Nihongi, in 698 a small force dispatched by Japanese government successfully claimed the Tane-jima, Yakushima, Amami, Tokunoshima and other islands.
[58] After the years of famine and epidemic during the Gihon's rule, Eiso introduced regular taxation system (of weapons, grains and cloth) in 1264 and as the government gained strength, the control extended from Okinawa toward the islands of Kume, Kerama, Iheya, and Amami Ōshima (1266).
The north and largest Hokuzan polity was the poorest due to forest and mountainous terrain (in which isolation was an advantage), with primitive farming and fishing.
[66][67] In 1392, 36 Chinese families from Fujian were invited by the chieftain of Okinawa Island's central polity (Chūzan) to settle near the port of Naha and to serve as diplomats, interpreters, and government officials.
[66] After the Kyūshū Campaign (1586–1587) by Toyotomi Hideyoshi, his assistant Kamei Korenori, who was interested in southern trade, wanted to be rewarded with the Ryukyu Islands.
A paper fan found during the Japanese invasions of Korea (1592–98) mentioning a title "Kamei, Lord of Ryukyu", reveals that Hideyoshi at least nominally offered the post although he had no legitimate claim upon the islands.
[73] As the Ming's influence weakened due to disorder in China, Japanese established posts in Southeast Asia, and the Europeans (Spanish and Portuguese) arrived, the kingdom's overseas trade began to decline.
As the king did not react, with the instruction of the shōgun, the Satsuma feudal domain of the Shimazu clan in Kyūshū incorporated some of kingdom's territory during the 1609 Invasion of Ryukyu.
A proposal by the 18th U.S. President Ulysses S. Grant for a sovereign Okinawa and the division of the other islands between China and Japan was rejected, with a last-minute decision by the Chinese government not to ratify the agreement rendering it null.
On three occasions between 1875 and 1879, the last Ryukyuan King, Shō Tai, refused to submit to the demands placed upon his people, and in 1879, his domain was formally abolished and established as Okinawa Prefecture, forcing his move to Tokyo with the reduced status of Viscount.
[92] Indoctrination into a militaristic and Emperor-centred ideology for children began from the age of beginning elementary school onwards;[93] the ultimate goal of this education was a total unification of the Ryukyuans into the Yamato people, embodying the ideal of ethnic purity,[94] with contemporary Nihonjiron literature for the time ignoring Japan's minorities[95]).
[98] Around and especially after the Japanese annexation of Taiwan in 1895, Japan's developmental focus shifted away from Okinawa, resulting in a period of famine known as "Sotetsu-jigoku" ("Cycad hell").
During this period the U.S. military requisitioned private land for the building of their facilities, with the former owners put into refugee camps, and its personnel committed thousands of crimes against the civilians.
[58][106] Since 1972 there have been extensive plans to bring Okinawa's economy up to the national level, as well continued support for the local culture and a revival of traditional arts started by the USCAR.
[58] As the Jōmon-Yayoi transition (c. 1000 BCE) represents the formative period of the contemporary Japanese people from a genetic standpoint, it is argued that the Japonic languages are related to the Yayoi migrants as well.
[145] After World War II, during the United States occupation, the Ryukyuan languages and identity were distinctively promoted, also because of ideo-political reasons to separate the Ryukyus from Japan.
[58] The foremost account, which claimed common origin between the Japanese and Ryukyuans, was made-up by Shō Shōken in the 17th century, to end up the pilgrimage of the Ryukyu king and chief priestess to the Kudaka island.
[155] During the Meiji period the government replaced Buddhism with Shintoism as the islands' state religion,[156] and ordered; rearrangement of statues and redesign of shrines and temples to incorporate indigenous deities into national Shinto pantheon; Shinto worship preceded indigenous, Buddhist, or Christian ritual; transformation of local divinities into guardian gods.
Most famous to tourists is the Momordica charantia, gōya (bitter melon), which is often mixed into a representative Okinawan stir fry dish known as champurū (Goya champuru).
[6] In remote districts their katakashira off-center topknot, similar to that of the Yami and some Filipino ethnic groups,[58] among men and women also disappeared in the early 20th century.
Other dwellings suggest a tropical origin, and some villages have high stone walls, with similar structural counterpart in Yami people at Orchid Island.
