Names
The islands are referred to as the in Japanese. In mainland China, they are known as the ''Diaoyu Islands'' ( zh, s=, p=Diàoyúdǎo) or more fully "Diaoyu Dao and its affiliated islands" ( zh, s=, p=Diàoyúdǎo jí qí fùshǔ dǎoyǔ),
while in Taiwan they are called the ''Diaoyutai Islands'' or ''Tiaoyutai Islands'' ( zh, t=, p=Diàoyútái liè yǔ).
In Western sources, the historical English name ''Pinnacle Islands'' is occasionally still used when neutrality among the competing national claims is desirable.
[ cites Hagstrom 2005; "The islands are also called 'Pinnacle Islands' for convenience and neutrality sake by Western scholars"]
In
Okinawan (northern Ryukyu), the islands are known as ', 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'' ( zh, t=順風相送, p=Shùnfēng Xiāngsòng) (1403) and ''Record of the Imperial Envoy's Visit to Ryūkyū'' ( zh, t=使琉球錄, p=Shǐ Liúqiú Lù) (1534). 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
The Ryukyu Kingdom was a kingdom in the Ryukyu Islands from 1429 to 1879. It was ruled as a Tributary system of China, tributary state of Ming dynasty, imperial Ming China by the King of Ryukyu, Ryukyuan monarchy, who unified Okinawa Island t ...

[Suganuma, ]
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 by
Hayashi Shihei. This text, which was published in Japan in 1785, described the
Ryūkyū Kingdom
The Ryukyu Kingdom was a kingdom in the Ryukyu Islands from 1429 to 1879. It was ruled as a Tributary system of China, tributary state of Ming dynasty, imperial Ming China by the King of Ryukyu, Ryukyuan monarchy, who unified Okinawa Island t ...
. 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.
In 1832, the
Oriental Translation Fund of Great Britain and Ireland supported the posthumous abridged publication of Titsingh's French translation.
The name, "Pinnacle Isles" was first used by
James Colnett, who charted them during his 1789–1791 voyage in the ''Argonaut''.
William Robert Broughton
William Robert Broughton (22 March 176214 March 1821) was a British naval officer in the late 18th century. As a lieutenant in the Royal Navy, he commanded HMS ''Chatham'' as part of the Vancouver Expedition, a voyage of exploration through t ...
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". Reference was made to the islands in
Edward Belcher's 1848 account of the voyages of HMS ''Sammarang''. Captain Belcher remarked that "the names assigned in this region have been too hastily admitted." Belcher reported anchoring off Pinnacle Island in March 1845.
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 ); ''Kuba-shima'' / ''Huangwei Yu'' (then called ''Ti-a-usu''); and ''Taishō-tō'' / ''Chiwei Yu''.
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.
The collective use of the name "Diaoyutai" to denote the entire group began with the advent of the controversy in the 1970s.
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.
The Japanese central government incorporated the islands into Okinawa Prefecture in January 1895 while still fighting China in the
First Sino-Japanese War
The First Sino-Japanese War (25 July 189417 April 1895), or the First China–Japan War, was a conflict between the Qing dynasty of China and the Empire of Japan primarily over influence in Joseon, Korea. In Chinese it is commonly known as th ...

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.
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.
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.
In 1988, a Japanese political group reconstructed a lighthouse on Uotsuri Island.

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.
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.

China's Foreign Ministry objected saying Beijing would not "sit back and watch its territorial sovereignty violated."
In 2014, Japan constructed a lighthouse and wharf featuring Japanese flag insignia on the islets.
Geography

The island group are known to consist of five uninhabited islets and three barren rocks. China has identified and named as many as 71 islets that belong to this group after the Japanese Cabinet released names for 39 uninhabited islands.
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.
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.
In ascending order of distances, the island cluster is located:

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." 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.
[ ]
* 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 territorial sovereignty. This map also depicts Taiwan as only about one-third the size of Okinawa's main island, and it is colored differently from mainland China,
which controlled Taiwan at the time. This suggests that the creator did not possess accurate knowledge.
* The islands were neither part of

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,
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.
* 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, 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.
* 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."
* 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.

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.

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.

In 2012 the Japanese Ministry of Foreign Affairs created a website in support of its claims; 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. 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 and was coincident with a three-party meeting (including

responded that the islands belong to Republic of China, and any moves to deny this fact are invalid. 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.
