Mudan incident In December 1871, a
Ryukyuan vessel shipwrecked on the southeastern tip of Taiwan and 54 sailors were killed by indigenous Taiwanese peoples. Four tribute ships were returning to the
Ryukyu Islands when they were blown off course on 12 December. Two ships were pushed towards Taiwan. One of them landed on Taiwan's western coast and made it back home with the help of Qing officials. The other one crashed into the eastern coast of southern Taiwan near Padiyudr Bay (). There were 69 passengers and 66 managed to make it to shore. Fifty-four of them were killed by
Paiwan while the remaining 12 were rescued by
Han Chinese who transferred them to Taiwan Prefecture (modern
Tainan). They then made their way to
Fujian province in mainland China and from there, the
Qing government arranged transport to send them home. They departed in July 1872. This event, known as the
Mudan incident, did not immediately cause any concern in Japan. A few officials knew of it by mid-1872 but it was not until April 1874 that it became an international concern. The repatriation procedure in 1872 was by the book and had been a regular affair for several centuries. From the 17th to 19th centuries, the Qing had settled 401 Ryukyuan shipwreck incidents both on the coast of mainland China and Taiwan. The
Ryukyu Kingdom did not ask Japanese officials for help regarding the shipwreck. Instead its king,
Shō Tai, sent a reward to Chinese officials in Fuzhou for the return of the 12 survivors.
Diplomacy On 30 August 1872,
Sukenori Kabayama, a general of the Imperial Japanese Army, urged the Japanese government to invade Taiwan's tribal areas. In September, Japan
dethroned the king of Ryukyu. On 9 October, Kabayama was ordered to conduct a survey in Taiwan. In 1873, Tanemomi Soejima was sent to communicate to the Qing court that if it did not extend its rule to the entirety of Taiwan, punish murderers, pay victims' families compensation, and agree to talk about the matter, Japan would take care of it. The Foreign Minister Sakimitsu Yanagihara believed that the perpetrators of the Mudan incident were "all Taiwan savages beyond Chinese education and law." Japan justified sending an expedition to Taiwan through linguistic interpretation of
huawai zhimin (lit. outside the sphere of civilization) to mean not part of China. Chinese diplomat
Li Hongzhang rejected the claim that the murder of Ryukyuans had anything to do with Japan once he learned of Japan's aspirations. However, after communications between the Qing and Yanagihara, the Japanese took their explanation to mean that the Qing government had not opposed Japan's claims to sovereignty over the Ryukyu Islands, disclaimed any jurisdiction over indigenous Taiwanese peoples, and had indeed consented to Japan's expedition to Taiwan. In the eyes of Japan and the foreign advisor
Charles Le Gendre, the indigenous people were "savages" who had no sovereign or international status, and therefore their territory was "terra nullius", free to be seized for Japan. The Qing argued that like in many other countries, the administration of the government did not stretch to every part of a country, similar to the Native American territories in the
United States or aboriginal territories in
Australia and
New Zealand, a view Le Gendre also took before his employment by the Japanese. Japan had already sent a student, Kurooka Yunojo, to conduct surveys in Taiwan in April 1873. Kabayama reached Tamsui on 23 August disguised as a merchant and surveyed eastern Taiwan. On 9 March 1874, the Taiwan Expedition prepared for its mission. The magistrate of the Taiwan Circuit learned of the impending Japanese invasion from a Hong Kong newspaper quoting a Japanese news item and reported it to Fujian authorities. Qing officials were taken by complete surprise due to the seemingly cordial relations with Japan at the time. On 17 May,
Saigō Jūdō led the main force, 3,600 strong, aboard four warships in Nagasaki headed to Tainan. On 6 June, the Japanese emperor issued a certificate condemning the Taiwan "savages" for killing our "nationals", the Ryukyuans killed in southeastern Taiwan. ==Expedition==
