Okinawa Island
Okinawa Island, also known as Okinawa Main Island, is the largest of the Okinawa Islands and the Ryukyu 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 long, an average wide, and has an area of. It is roughly south of the main island of Kyushu and the rest of Japan. It is 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.
History
Shell mound eras
Early Okinawan history is defined by midden or shell heap culture and is divided into Early, Middle, and Late Shell Mound periods. The Early Shell Mound period was a hunter-gatherer society, with the wave-like opening Jōmon pottery. In the latter part of this period, archaeological sites moved near the seashore, suggesting the engagement of people in fishing. On Okinawa, rice was not cultivated until the Middle Shell Mound period. Shell rings for arms made of shells obtained in the Sakishima Islands, namely Miyakojima and Yaeyama islands, were imported by Japan. In these islands, the presence of shell axes from 2,500 years ago suggests the influence of a southeastern-Pacific culture.File:First Ryukyan mission to Edo.JPG|thumb|left|The first of the Ryukyuan missions to Edo, the capital of Tokugawa shogunate
After the late Shell Mound period, agriculture started about the 12th century, and the population center moved from the seashore to higher places. This period is called the Gusuku period. Gusuku is a term used for the distinctive Ryukyuan form of castles or fortresses. Many gusuku and related cultural remains in the Ryukyu Islands have been listed by UNESCO as World Heritage Sites. There are three perspectives regarding the nature of gusuku: that they were holy places, dwellings encircled by stones, and castles of the rulers. In this period, porcelain trade between Okinawa and other countries became commonplace, and Okinawa was an important relay point in eastern-Asian trade. Ryukyuan kings, such as Shunten and Eiso, were important rulers. An attempted Mongolian invasion in 1291 during the Eiso dynasty failed. Hiragana was imported from Japan by Ganjin in 1265. Noro, village priestesses of the Ryukyuan religion, appeared.
Sanzan era and Ryūkyū Kingdom
The Sanzan period began in 1314 when the kingdoms of Hokuzan and Nanzan declared independence from Chūzan. The three kingdoms competed with one another for recognition as a vassal state of Ming China. King Satto, leading Chūzan, was very successful, establishing relations with Korea and Southeast Asia as well as China. The Hongwu Emperor of China sent a large population of Chinese migrants, primarily consisting of 36 large families from Fujian Province, in 1392 at the request of the Ryukyuan king. The purpose of the migration was to increase the population of the Ryukyuan kingdom as well as enhance maritime relations between the Chinese empire and the Ryukyuan kingdom. The Chinese migrants assisted the Ryukyuans in developing their technology and diplomatic relations. In 1407, however, a man named Hashi overthrew Satto's descendant, King Bunei, and installed his father, Shishō, as king of Chūzan.In 1429, King Shō Hashi completed the unification of the three kingdoms and founded the Ryūkyū Kingdom with its capital at Shuri Castle. His descendants conquered the Amami Islands. In 1469, King Shō Taikyū died, so the royal government chose a man named Kanemaru as the new king, who chose the name Shō En and established the Second Shō dynasty. His son Shō Shin conquered the Sakishima Islands and centralized the royal government, the military, and the noro priestesses.
Satsuma Domain
In 1609, the Japanese Satsuma Domain launched the invasion of Ryukyu, ultimately capturing the king and his capital after a long struggle. Ryukyu was forced to cede the Amami Islands and become a vassal of Satsuma. The kingdom became both a tributary of China and a tributary of Japan. Because China would not make a formal trade agreement unless a country was a tributary state, the kingdom was a convenient loophole for Japanese trade with China. When Japan officially closed off trade with European nations except for the Dutch, Nagasaki, Tsushima, and Kagoshima became the only Japanese trading ports offering connections with the outside world.At some time, karate came into existence as a type of systematized martial arts.
18th and 19th centuries
Several Europeans visited Ryukyu starting in the late 18th century. The most important visits to Okinawa were from Captain Basil Hall in 1816 and Commodore Matthew C. Perry in 1852. A Christian missionary, Bernard Jean Bettelheim, lived in the Gokoku-ji temple in Naha from 1846 to 1854.In 1879, Japan annexed the entire Ryukyu archipelago. The Meiji government then established Okinawa Prefecture. The monarchy in Shuri was abolished, and the deposed King Shō Tai was forced to relocate to Tokyo.
Pacific War
Okinawa Island had the bloodiest ground battle of the Pacific War from 1 April to 22 June 1945. During this 82-day-long battle, about 95,000 Imperial Japanese Army troops and 20,195 Americans were killed. The Cornerstone of Peace at the Peace Memorial Park in Itoman lists 149,193 persons from Okinawa—approximately one quarter of the civilian population—were either killed or committed suicide during the Battle of Okinawa and the Pacific War. Very few Japanese ended up in POW camps. This may have been because of Japanese soldiers' reluctance to surrender. The total number of casualties shocked American military strategists. This made them apprehensive to invade the other main islands of Japan, because it would result in very high casualties.American occupation
Japan became a pacifist country with the 1947 constitution, so America decided to step into the role of protecting Japan against foreign threats. During the American military occupation of Japan, which followed the Imperial Japanese surrender on 2 September 1945, in Tokyo Bay, the United States controlled Okinawa Island and the rest of the Ryukyu Islands. The Amami Islands were returned to Japanese control in 1953. The remaining Ryukyu Islands were returned to Japan on 17 June 1971. America kept numerous U.S. military bases on the islands. There are 32 United States military bases on Okinawa Island by the U.S.-Japan alliance since 1951. U.S. bases on Okinawa played critical roles in the Korean War, Vietnam War, Laotian Civil War, Cambodian campaign, War in Afghanistan, and Iraq War. Okinawa served as a prime staging post for the aforementioned wars. Its ports and airports were used to transport supplies. The base at Camp Chinen, Nanjo City was used by the CIA for covert operations. In 1965, Admiral Ulysses S. Grant Sharp stated that "Without Okinawa, we couldn't continue fighting the Vietnam war."Intense use of the island by the U.S. military caused damage to the environment and residents. There were oil and fuel spills. Exposure to toxic substances caused illness of service members such as a nerve agent leak in 1969. Aircraft crashes, hit-and runs and murders killed residents. The perpetrators were often unpunished, since they could not be prosecuted in Okinawa Courts. The 1970s and 1980s also had severe pollution of waterways and wells with PFAS: toxic chemicals in foam used by fire fighting training at U.S. facilities such as Kadena Air Base.
