The Senkaku Islands,[a] also known as the Pinnacle Islands or the Diaoyu Islands[b] in China and as the Tiaoyutai Islands[c] in Taiwan, are a group of uninhabited islands in the East China Sea, administered by Japan.
The islands are the focus of a territorial dispute between Japan and China and between Japan and Taiwan.[9] China claims the discovery and ownership of the islands from the 14th century, while Japan maintained ownership of the islands from 1895 until its surrender at the end of World War II. The United States administered the islands as part of the United States Civil Administration of the Ryukyu Islands from 1945 until 1972, when the islands returned to Japanese control under the Okinawa Reversion Agreement between the United States and Japan.[10] The discovery of potential undersea oil reserves in 1968 in the area was a catalyst for further interest in the disputed islands.[11][12][13][14][15] Despite the diplomatic stalemate between China and Taiwan, both governments agree that the islands are part of Taiwan as part of Toucheng Township in Yilan County. Japan administers and controls the Senkaku islands as part of the city of Ishigaki in Okinawa Prefecture. It does not acknowledge the claims of China nor Taiwan, but it has not allowed the Ishigaki administration to develop the islands.
As a result of the dispute, the public is largely barred from approaching the uninhabited islands, which are about a seven-hour boat ride from Ishigaki. Vessels from the Japan Coast Guard pursue Chinese ships crossing the maritime boundary in what one visiting journalist described in 2012 as "an almost cold war-style game of cat-and-mouse", and fishing and other civilian boats are prevented from getting too close to avoid a provocative incident.[16]
The islands are referred to as the Senkaku Islands (尖閣諸島, Senkaku-shotō, variants: 尖閣群島Senkaku-guntō[18] and 尖閣列島Senkaku-rettō[19]) in Japanese. In mainland China, they are known as the Diaoyu Islands (Chinese: 钓鱼岛; pinyin: Diàoyúdǎo) or more fully "Diaoyu Dao and its affiliated islands" (Chinese: 钓鱼岛及其附属岛屿; pinyin: Diàoyúdǎo jí qí fùshǔ dǎoyǔ),[20] while in Taiwan they are called the Diaoyutai Islands or Tiaoyutai Islands[21][22][23][24] (Chinese: 釣魚臺列嶼; pinyin: Diàoyútái liè yǔ).[25][26][27][28] In Western sources, the historical English name Pinnacle Islands is occasionally still used when neutrality among the competing national claims is desirable.[29][30][31][32]
In Okinawan (northern Ryukyu), the islands are known as ʔiyukubajima (魚蒲葵島),[33] while their Yaeyama (southern Ryukyu) name is iigunkubajima.
Chinese records of these islands date back to as early as the 15th century when they were referred as Diaoyu in books such as Voyage with a Tail Wind (Chinese: 順風相送; pinyin: Shùnfēng Xiāngsòng) (1403) [34] and Record of the Imperial Envoy's Visit to Ryūkyū (Chinese: 使琉球錄; pinyin: Shǐ Liúqiú Lù) (1534).[citation needed] Adopted by the Chinese Imperial Map of the Ming Dynasty, the Chinese name for the island group (Diaoyu) and the Japanese name for the main island (Uotsuri) both mean "fishing".
History
Early history
Historically, the Chinese had used the uninhabited islands as navigational markers in making the voyage to the Ryukyu Kingdom upon commencement of diplomatic missions to the kingdom, "resetting the compass at a particular isle in order to reach the next one".[35]
The first published description of the islands in Europe appears in a book imported by Isaac Titsingh in 1796. His small library of Japanese books included Sangoku Tsūran Zusetsu (三國通覧圖說, An Illustrated Description of Three Countries) by Hayashi Shihei.[36] This text, which was published in Japan in 1785, described the Ryūkyū Kingdom.[37] Hayashi followed convention in giving the islands their Chinese names in his map in the text, where he coloured them in the same pink as China.[38]
The name, "Pinnacle Isles" was first used by James Colnett, who charted them during his 1789–1791 voyage in the Argonaut.[40]William Robert Broughton sailed past them in November 1797 during his voyage of discovery to the North Pacific in HMS Providence, and referred to Diaoyu Island/Uotsuri Island as "Peaks Island".[41] Reference was made to the islands in Edward Belcher's 1848 account of the voyages of HMS Sammarang.[42] Captain Belcher remarked that "the names assigned in this region have been too hastily admitted."[43] Belcher reported anchoring off Pinnacle Island in March 1845.[44]
In the 1870s and 1880s, the English name Pinnacle Islands was used by the British navy for the rocks adjacent to the largest island Uotsuri-shima / Diaoyu Dao (then called 和平嶼; hô-pîng-sū; 'Peace Island in Hokkien'); Kuba-shima / Huangwei Yu (then called Ti-a-usu); and Taishō-tō / Chiwei Yu.[45]
A Japanese navy record issued in 1886 first started to identify the islets using equivalents of the Chinese and English terms employed by the British. The name "Senkaku Retto" is not found in any Japanese historical document before 1900 (the term "Senkaku Gunto" began being used in the late 19th century), and first appeared in print in a geography journal published in 1900. It was derived from a translation of the English name Pinnacle Islands into a Sinicized Japanese term "Sento Shoto" (as opposed to "Senkaku Retto", i.e., the term used by the Japanese today), which has the same meaning.[46]
The collective use of the name "Diaoyutai" to denote the entire group began with the advent of the controversy in the 1970s.[47]
Control of the islands by Japan and the US
As the uninhabited islets were historically used as maritime navigational markers, they were never subjected to administrative control other than the recording of the geographical positions on maps, descriptions in official records of Chinese missions to the Ryukyu Kingdom, etc.[35]
The Japanese central government incorporated the islands into Okinawa Prefecture in January 1895 while still fighting China in the First Sino-Japanese War.[38] Around 1900, Japanese entrepreneur Koga Tatsushirō (古賀 辰四郎) constructed a bonito fish processing plant on the islands, employing over 200 workers. The business failed around 1940 and the islands have remained deserted ever since.[48] In the 1970s, Koga Tatsushirō's son Zenji Koga and Zenji's wife Hanako sold four islets to the Kurihara family of Saitama Prefecture. Kunioki Kurihara[49] owned Uotsuri, Kita-Kojima, and Minami-Kojima. Kunioki's sister owned Kuba.[50]
The islands came under US government occupation in 1945 after the surrender of Japan ended World War II.[48] In 1969, the United Nations Economic Commission for Asia and the Far East (ECAFE) identified potential oil and gas reserves in the vicinity of the Senkaku Islands.[51] In 1971, the Okinawa Reversion Treaty passed the U.S. Senate, returning the islands to Japanese control in 1972.[52] Also in 1972, the Republic of China government and People's Republic of China government officially began to declare ownership of the islands.[53]
Since 1972, when the islands reverted to Japanese government control, the government of Ishigaki has been given civic authority over the territory. The Japanese central government, however, has prohibited Ishigaki from surveying or developing the islands.[48][54]
In 1978, a Japanese political group constructed the first lighthouse on Uotsuri island and grazed two goats. Goats have since proliferated and affected the island's vegetation.[55]
In 1979 an official delegation from the Japanese government composed of 50 academics, government officials from the Foreign and Transport ministries, officials from the now-defunct Okinawa Development Agency, and Hiroyuki Kurihara, visited the islands and camped on Uotsuri for about four weeks. The delegation surveyed the local ecosystem, finding moles and sheep, studied the local marine life, and examined whether the islands would support human habitation.[50]
In 1988, a Japanese political group reconstructed a lighthouse on Uotsuri Island.[56]
In 2005, a Japanese fisherman who owned a lighthouse at Uotsuri Island expressed his intention to relinquish the ownership of the lighthouse, and the lighthouse became a national property pursuant to the provisions of the Civil Code of Japan. Since then, the Japan Coast Guard has maintained and managed the Uotsuri lighthouse.[56]
From 2002 to 2012, the Ministry of Internal Affairs and Communications paid the Kurihara family ¥25 million a year to rent Uotsuri, Minami-Kojima and Kita-Kojima. Japan's Ministry of Defense rents Kuba island for an undisclosed amount. Kuba is used by the U.S. military as a practice aircraft bombing range. Japan's central government completely owns Taisho island.[50][57]
On December 17, 2010, the city of Ishigaki designated January 14 as "Pioneering Day" to commemorate Japan's 1895 incorporation of the Senkaku Islands. China condemned Ishigaki's actions.[60]
In May 2012, both the Tokyo Metropolitan and Japanese central governments announced plans to negotiate purchase of Uotsuri, Kita-Kojima, and Minami-Kojima from the Kurihara family,[50] and on September 11, 2012, the Japanese government nationalized its control over Minami-kojima, Kita-kojima, and Uotsuri islands by purchasing them from the Kurihara family for ¥2.05 billion.[61] China's Foreign Ministry objected saying Beijing would not "sit back and watch its territorial sovereignty violated."[62]
In 2014, Japan constructed a lighthouse and wharf featuring Japanese flag insignia on the islets.[63]
Geography
The island group are known to consist of five uninhabited islets and three barren rocks.[64] China has identified and named as many as 71 islets that belong to this group after the Japanese Cabinet released names of 39 uninhabited islands.[65][66]
These minor features in the East China Sea are located approximately 120 nautical miles northeast of Taiwan, 200 nautical miles east of the Chinese mainland and 200 nautical miles southwest of the Japanese island of Okinawa.[67]
According to one visitor, Uotsuri-shima, the largest of the islands, consists of a pair of rocky gray mountains with steep, boulder-strewn slopes rising almost straight from the water's edge. Other, nearby islands were described as large rocks covered by low vegetation.[16]
In ascending order of distances, the island cluster is located:
The depth of the surrounding waters of the continental shelf is approximately 100–150 metres (330–490 ft) except for the Okinawa Trough on the south.[84] The shelf is shallow enough that the western islands were likely connected to the mainland during the Last Glacial Period.[85]
Geology
Uotsuri, Kitakojima, Minamikojima and surrounding islets are sedimentary in origin, predominantly consisting of probably Miocene aged sandstone and sandstone-conglomerate, with subordinate conglomerate, coal seams up to 10 centimetres thick, and rare siltstone beds. The sedimentary strata have around 300 metres of exposed thickness at Uotsuri, and have SW-NE, EW and NW-SE strikes, with a general inclination of a dip of less than 20 degrees towards the North.[86] These strata are intruded by sheets of Mio-Plioceneporphyritichornblendediorite, and are fringed by recent coral outcrops and surface talus deposits. Kuba and Taisho are volcanic in origin, with Kuba comprising "pyroxeneandesite, lava, volcanic bombs, pumice, limestone, and other rocky material" and Taisho is thought to be consist of "andesite, tuffbreccia, and tuffaceous sandstone".[87]
Wildlife
Plants
Permission for collecting herbs on three of the islands was recorded in an Imperial Chinese edict of 1893.[88]
Uotsuri-shima, the largest island, has a number of endemic species such as the Senkaku mole (Mogera uchidai) and Okinawa-kuro-oo-ari ant. Due to the introduction of domestic goats to the island in 1978, the Senkaku mole is now an endangered species.[94] The striped field mouse (Apodemus agrarius) has also been noted to be present on Uotsuri. Surveys from 1900 to 1953 and noted the presence of the Asian house shrew, black rats and fruit bats but these were not noted in more recent surveys.[89][91]
Territorial sovereignty over the islands and the maritime boundaries around them are disputed between the People's Republic of China, the Republic of China, and Japan.
The People's Republic and Republic of China claim that the islands have been a part of Chinese territory since at least 1534. China acknowledges that Japan took control of the islands in 1894–1895 during the first Sino-Japanese War, through the signature of the Treaty of Shimonoseki. China asserts that the Potsdam Declaration required that Japan relinquish control of all islands except for "the islands of Honshū, Hokkaidō, Kyūshū, Shikoku and such minor islands as we determine", and China states that this means control of the islands should pass to Republic of China, which was part of China at the time of the first Sino-Japanese War as well as of the San Francisco Peace Treaty. Both the People's Republic of China (PRC)[96] and the Republic of China (ROC)[97] respectively separately claim sovereignty based on arguments that include the following points:
Discovery and early recording in maps and travelogues.[98]
The islands being China's frontier off-shore defence against wokou (Japanese pirates) during the Ming and Qing dynasties (1368–1911).
Japan taking control of the islands in 1895 at the same time as the First Sino-Japanese War was happening. Furthermore, correspondence between Foreign Minister Inoue and Interior Minister Yamagata in 1885, warned against the erection of national markers and developing their land to avoid Qing Dynasty suspicions.[98][100][101]
The Potsdam Declaration stating that "Japanese sovereignty shall be limited to the islands of Honshū, Hokkaidō, Kyūshū, Shikoku and such minor islands as we determine", and "we" referred to the victors of the Second World War who met at Potsdam and Japan's acceptance of the terms of the Declaration when it surrendered.[100][102][103]
Japan does not accept that there is a dispute, asserting that the islands are an integral part of Japan.[105] Japan has rejected claims that the islands were under China's control prior to 1895, and that these islands were contemplated by the Potsdam Declaration or affected by the San Francisco Peace Treaty.[106]
...the Okinawa Trough proves that the continental shelves of China and Japan are not connected, that the Trough serves as the boundary between them, and that the Trough should not be ignored ....[107]
Japan's interpretation of the geography is that
...the trough is just an incidental depression in a continuous continental margin between the two countries ... [and] the trough should be ignored ....[107]
The stance given by the Japanese Ministry of Foreign Affairs is that the Senkaku Islands are clearly an inherent territory of Japan, in light of historical facts and based upon international law, and the Senkaku Islands are under the valid control of Japan. They also state "there exists no issue of territorial sovereignty to be resolved concerning the Senkaku Islands."[108][109] The following points are given:
The islands had been uninhabited and showed no trace of having been under the control of China prior to 1895.[110]
The purposes of maps and the intentions behind their creators can vary significantly, and the mere existence of an ancient map does not substantiate claims of territorial sovereignty. The map (1785) cited by China from Hayashi Shihei does not provide evidence that the creator's coloring was intended to indicate an understanding of territorial sovereignty. This map depicts Taiwan as being only about one-third the size of Okinawa's main island and is colored differently from that of mainland China. This suggests that the creator did not possess accurate knowledge.[111]
The islands were neither part of Taiwan nor part of the Pescadores Islands, which were ceded to Japan by the Qing Dynasty of China in Article II of the May 1895 Treaty of Shimonoseki,[110] thus were not renounced by Japan under Article II of the San Francisco Peace Treaty, which serves as the international law addressing the aftermath of WW2.[112]
A resident of Okinawa Prefecture who had been engaging in activities such as fishery around the Senkaku Islands since around 1884 made an application for the lease of the islands, and approval was granted by the Meiji Government in 1896. After this approval, he sent a total of 248 workers to those islands and ran the following businesses: constructing piers,[113] collecting bird feathers, manufacturing dried bonito, collecting coral, raising cattle, manufacturing canned goods and collecting mineral phosphate guano (bird manure for fuel use). The fact that the Meiji Government gave approval concerning the use of the Senkaku Islands to an individual, who in turn was able to openly run these businesses mentioned above based on the approval, demonstrates Japan's valid control over the Islands.[114]
In May 1920, a thank-you letter from the Republic of China's consulate in Nagasaki regarding the rescue of Chinese fishermen in distress near the Senkaku Islands by Japanese fishermen included the notation "Senkaku Islands, Yaeyama District, Okinawa Prefecture, Empire of Japan."[111]
Though the islands were controlled by the United States as an occupying power between 1945 and 1972, Japan has since 1972 exercised administration over the islands.
In 1953, the official Chinese newspaper People's Daily published an article that explicitly stated that the Ryukyu Islands consist of seven island groups, including the Senkaku Islands. Additionally, in the world atlas published by the China Map Press in 1958 (reprinted in 1960), these islands were clearly referred to as the "Senkaku Islands" and considered part of Okinawa.[115]
Republic of China and People Republic of China only started claiming ownership of the islands in 1971, following a May 1969 United Nations report that a large oil and gas reserve may exist under the seabed near the islands.[116][111]
In 2012 the Japanese Ministry of Foreign Affairs created a website in support of its claims;[117] in late 2014 the National Marine Data and Information Service, a department under the State Oceanic Administration of People's Republic of China created a website of its own to support its claims.[118][119] In 2016, Chinese fishing, Coast Guard and other vessels were entering the territorial waters around the islands almost daily and in August 2016 the Japanese foreign minister Fumio Kishida reportedly told China's foreign minister Wang Yi "that the activity represented an escalation of tensions" according to Japanese sources. It was the first meeting of the top diplomats since the Permanent Court of Arbitration ruling against China's South China Sea claims[120][121] and was coincident with a three-party meeting (including South Korea) relative to a North Korean submarine-launched missile in the Sea of Japan.[122]
On 22 June 2020, the Ishigaki City Council voted to change the name of the area containing the Senkaku Islands from "Tonoshiro" to "Tonoshiro Senkaku".[123] Republic of China's Ministry of Foreign Affairs responded that the islands belong to Republic of China, and any moves to deny this fact are invalid.[124] The Taiwanese government and the opposition KMT party also condemned the council's move, saying the Islands are ROC territory and the nation would not give up even "an inch" of its sovereignty.[125]
In popular culture
Diaoyu Islands: The Truth is a documentary film produced by Chris D. Nebe and J.J. Osbun of Monarex Hollywood Corporation and directed by Chris D. Nebe. Nebe calls on the Japanese Government to cede the islands to China, asserting that Japan has no justifiable claim to the islands, and that the United States of America has turned a blind eye in Japan's favor due to the need of the United States to have a strong ally between it and China. Reception of the film was positive in Chinese media, while the Australian Broadcasting Corporation's Correspondents Report called Nebe a 'Chinese propagandist' in 2014.[126]

The question of the disputed Senkaku Islands remained relatively dormant throughout the 1950s and 1960s, probably because these small uninhabited islands held little interest for the three claimants. The Senkaku Islands issue was not raised until the Economic Commission for Asia and the Far East (hereinafter 'ECAFE') of the United Nations Economic and Social Council suggested the possible existence of large hydrocarbon deposit in the waters off the Senkaku Islands. ... This development prompted vehement statements and counter-statements among the claimants.

The Diaoyu/Senkaku Islands issue did not re-surface until 1969 when the Economic Commission for Asia and the Far East of the United Nations Economic and Social Council reported that the continental shelf of the East China "might contain one of the most prolific oil and gas reservoirs of the world, possibly comparing favourably with the Persian Gulf." Then both China and Japan had high expectations that there might be large hydrocarbon deposits in the waters off the Diaoyu/Senkaku Islands. The Law of the Sea at that time emphasized the theory of natural prolongation in determining continental shelf jurisdiction. Ownership of the Diaoyu/Senkaku Islands would permit the owner to a large area of the continental shelf that may have rich sources of gas and oil. Such a dispute is obviously related to the awakening interest by the world's states in developing offshore energy resources to meet the demand of their economies.

The islands had temporarily come under American control after the Second World War, but the sovereignty over the islands, was handed over to Japan in 1972 with the reversion of Okinawa.However, the PRC and ROC governments both made a territorial claim to the Senkaku Islands, soon after the United Nation Economic Commission issued in 1969 a report suggesting considerable reserve of submarine oil and gas resources around the islands.

The dispute surfaced with the publication of a seismic survey report under the auspices of the UN Economic Commission for Asia and the Far East (ECSFE) in 1968, which mentioned the possibility of huge oil and gas reserves in the area; this was confirmed by a Japanese report in 1969. Greg Austin mentions that Beijing started its claim to the Senkaku Islands for the first time in 1970, after Japanese government protested to the government in Taiwan about its allocation of oil concessions in the East China Sea, including the area of the Senkaku Islands.

For a long time following the entry into force of the San Francisco Peace Treaty China/Taiwan raised no objection to the fact that the Senkaku Islands were included in the area placed under US administration in accordance with the provisions of Article of the treaty, and USCAP No. 27. In fact, neither China nor Taiwan had taken up the question of sovereignty over the islands until the latter half of 1970 when evidence relating to the existence of oil resources deposited in the East China Sea surfaced. All this clearly indicates that China/Taiwan had not regarded the Senkaku Islands as a part of Taiwan. Thus, for Japan, none of the alleged historical, geographical and geological arguments set forth by China/Taiwan are acceptable as valid under international law to substantiate China's territorial claim over the Senkaku Islands.
