There was also a divine woman named "Uchinaa" in the book Omoro Sōshi, a compilation of ancient poems and songs from Okinawa Island.
The Chinese monk Jianzhen, who traveled to Japan in the mid-8th century CE to promote Buddhism, wrote "Okinawa" as 阿児奈波 (anjenaʒpa).
One theory claims that the earliest inhabitants of these islands crossed a prehistoric land bridge from modern-day China, with later additions of Austronesians, Micronesians, and Japanese merging with the population.
Chūzan Seikan then tells the story of a Japanese samurai, Minamoto no Tametomo (1139–70), who fought in the Hogen Rebellion of 1156 and fled first to Izu Island and then to Okinawa.
He had relations with the sister of the Aji of Ōzato and sired Shunten, who then led a popular rebellion against Riyu and established his own rule at Urasoe Castle.
[8] Shunten's dynasty ended in the third generation when his grandson, Gihon, abdicated, went into exile, and was succeeded by Eiso, who began a new royal lineage.
There are three perspectives regarding the nature of gusukus: 1) a holy place, 2) dwellings encircled by stones, 3) a castle of a leader of people.
Much of the foundational organization of the kingdom's administration and economy stemmed from developments which occurred during Shō Shin's reign.
[citation needed] This period of effective outside control also featured the first international matches of Go, as Ryukyuan players came to Japan to test their skill.
[citation needed] In the years leading up to World War II, the Japanese government sought to reinforce national solidarity in the interests of militarization.
In addition to the Japanese military personnel who died in the Battle for Okinawa, well over one third of the civilian population, which numbered approximately 300,000 people, were killed.
Many important documents, artifacts, and sites related to Ryukyuan history and culture were also destroyed, including the royal Shuri Castle.
[citation needed] Due to fears concerning their fate during and after the invasion, the Okinawan people hid in caves and in family tombs.
Several mass deaths occurred, such as in the "Cave of the Virgins", where many Okinawan school girls committed suicide by jumping off cliffs for fear of rape.
Similarly, whole families committed suicide or were killed by near relatives in order to avoid suffering what they believed would be a worse fate at the hands of American forces; for instance, on Zamami Island at Zamami Village, almost everyone living on the island committed suicide two days after Americans landed.
"[attribution needed][36] Massive casualties in the Yaeyama Islands caused the Japanese military to force people to evacuate from their towns to the mountains, even though malaria was prevalent there.
Many military historians believe that the ferocity of the Battle of Okinawa led directly to the American decision to use the atomic bomb on Hiroshima and Nagasaki.
A prominent holder of this view is Victor Davis Hanson, who states it explicitly in his book Ripples of Battle: "because the Japanese on Okinawa, including native Okinawans, were so fierce in their defense (even when cut off, and without supplies), and because casualties were so appalling, many American strategists looked for an alternative means to subdue mainland Japan, other than a direct invasion.
"[37] After the beginning of World War II, the Japanese military conscripted school girls (15 to 16 years old) to join a group known as the Princess Lilies (Hime-yuri) and to go to the battle front as nurses.
During the occupation, American military personnel were exempt from domestic jurisdiction since Okinawa was an occupied territory of the United States.
The United States dollar was the official currency used, and cars drove on the right, American-style, as opposed to on the left as in Japan.
The U.S. used their time as occupiers to build large army, air force, navy, and marine bases on Okinawa.
U.S. President Richard Nixon and Japanese Prime Minister Eisaku Satō later signed the Okinawa Reversion Agreement in Washington, D.C. on June 17, 1971.
The locations of suspected Agent Orange contamination include Naha port, Higashi, Camp Schwab, and Chatan.
The defoliant might have been tested in Okinawa's northern area between Kunigami and Higashi by the US Army's 267th Chemical Service Platoon to assess its potential usefulness in Vietnam.
[47] In 2012 a US Army environmental assessment report, published in 2003, was discovered which stated that 25,000 55-gallon drums of Agent Orange had been stored on Okinawa before being taken to Johnston Atoll for disposal.
[48] In February 2013, an internal US DoD investigation concluded that no Agent Orange had been transported to, stored, or used on Okinawa.
In 1995, two Marines and a sailor kidnapped and raped a 12-year-old girl, and, under the SOFA with the U.S., local police and prosecutors were unable to get access to the troops until they were able to prepare an indictment.
[55] In the 1990s, a Special Actions Committee was set up to prepare measures to ease tensions, most notably the return of approximately 50 square kilometres (19 sq mi) to the Japanese state.
[56][57][58][59][60] In a similar manner, unexploded ordnance from WWII continues to be a danger, especially in sparsely-populated areas where it may have lain undisturbed or been buried.
