Pacific War

The Pacific War, sometimes called the Asia-Pacific War, was the theater of World War II that was fought in the Pacific and Asia. It was fought over a vast area that included the Pacific Ocean and islands, the South West Pacific, South-East Asia, and in China (including the 1945 Soviet–Japanese conflict). The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more widely accepted that the Pacific War itself began on 7/8 December 1941, when Japan invaded Thailand and attacked the British possessions of Malaya, Singapore, and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island, Guam and the Philippines. The Pacific War saw the Allies pitted against Japan, the latter briefly aided by Thailand and to a much lesser extent by the Axis allied Germany and Italy. The war culminated in the atomic bombings of Hiroshima and Nagasaki, and other large aerial bomb attacks by the Allies, accompanied by the Soviet declaration of war and invasion of Manchuria on 9 August 1945, resulting in the Japanese announcement of intent to surrender on 15 August 1945. The formal surrender of Japan ceremony took place aboard the battleship in Tokyo Bay on 2 September 1945. Japan's Shinto Emperor was forced to relinquish much of his authority and his divine status through the Shinto Directive in order to pave the way for extensive cultural and political reforms. After the war, Japan lost all rights and titles to its former possessions in Asia and the Pacific, and its sovereignty was limited to the four main home islands.

Ryukyuan people

The; also Lewchewan or) are the indigenous peoples of the Ryukyu Islands between the islands of Kyushu and Taiwan. Politically, they live in either Okinawa Prefecture or Kagoshima Prefecture. Their languages make up the Ryukyuan languages, considered to be one of the two branches of the Japonic language family, the other being Japanese and its dialects. Ryukyuans are not a recognized minority group in Japan, as Japanese authorities consider them just a subgroup of the Japanese people, akin to the Yamato people and Ainu. Although unrecognized, Ryukyuans constitute the largest ethnolinguistic minority group in Japan, with 1.3 million living in Okinawa Prefecture alone. There is also a considerable Ryukyuan diaspora. As many as 600,000 more ethnic Ryukyuans and their descendants are dispersed elsewhere in Japan and worldwide; mostly in Hawaii and, to a lesser extent, in other territories where there is also a sizable Japanese diaspora. In the majority of countries, the Ryukyuan and Japanese diaspora are not differentiated so there are no reliable statistics for the former. Recent genetic and anthropological studies indicate that the Ryukyuans are significantly related to the Ainu people and share the ancestry with the indigenous prehistoric Jōmon period (pre 10,000–1,000 BCE) people, who arrived from Southeast Asia, and with the Yamato people who are mostly an admixture of the Yayoi period (1,000 BCE–300 CE) migrants from East Asia (specifically China and the Korean peninsula). The Ryukyuans have a specific culture with some matriarchal elements, native religion, and cuisine which had fairly late 12th century introduction of rice. The population lived on the islands in isolation for many centuries, and in the 14th century from the three divided Okinawan political polities emerged the Ryukyu Kingdom (1429–1879) which continued the maritime trade and tributary relations started in 1372 with Ming dynasty China. In 1609 the kingdom was invaded by Satsuma Domain which allowed its independence being in vassal status because the Tokugawa Japan was prohibited to trade with China, being in dual subordinate status between both China and Japan. During the Meiji period, the kingdom became Ryukyu Domain (1872–1879), after which it was politically annexed by the Empire of Japan. In 1879, after the annexation, the territory was reorganized as Okinawa Prefecture with the last king Shō Tai forcibly exiled to Tokyo. China renounced its claims to the islands in 1895. During this period, Okinawan ethnic identity, tradition, culture and language were suppressed by the Meiji government, which sought to assimilate the Ryukyuan people as Japanese (Yamato). After World War II, the Ryūkyū Islands were occupied by the United States between 1945–1950 and 1950–1972. During this time, there were many violations of human rights. Since the end of World War II, there exists strong resentment against the Japanese government and US military facilities stationed in Okinawa, as seen in the Ryukyu independence movement. United Nations special rapporteur on discrimination and racism Doudou Diène in his 2006 report, noted perceptible level of discrimination and xenophobia against the Ryukyuans, with the most serious discrimination they endure linked to their dislike of American military installations in the archipelago. An investigation into fundamental human rights was suggested.
