The Senkaku Islands or Diaoyutai Islands are a group of disputed, uninhabited islands currently administered by Japan, but claimed by the People's Republic of China and the Republic of China (Taiwan). They are also known as the Pinnacle Islands, a name given by British navigators, which is also the probable source for the Japanese name. The Chinese name for the island group (Diaoyu) and the Japanese name for the main island (Uotsuri) both literally mean "Angling". Their status has emerged as a major issue in foreign relations between China and Japan. Relations between the PRC and the ROC have also complicated the situation.
- Total islands area: 7 km²
- Population: 0

In Japan, the islands are considered part of the Southwest Islands. They are 170 km north of Ishigaki Island, Japan; 170 km northeast of Keelung, Taiwan; and 410 km west of Okinawa Island. The PRC considers that the islands sit on the edge of the continental shelf of mainland Asia, and are separated from the Ryukyu Islands by a sea trench, while Japan considers that the continental shelf stretches to the much deeper Nansei-shoto Trench, east to the Southwest Islands and that the islands and the Ryukyu Islands are on the same continental shelf. The group is made up of five small volcanic islands:
 Uotsuri Jima/Diaoyu Dao
Uotsuri Jima (魚釣島) or Diaoyu Dao (釣魚島本島 "Angling Island" or 主島) is the largest island of the Senkaku Islands. The Island located at has an area of 4.319 km² and a highest elevation of 383m.
Uotsuri jima has a number of endemic species such as the Senkaku mole ( Nesoscaptor uchidai) and Okinawa-kuro-oo-ari ant, but these have become threatened by domestic goats that were introduced to the island in 1978 and whose population has increased to over 300 since that time.
 Kuba Jima/Huangwei Yu
Kuba Jima (久場島) or Huangwei Yu (黃尾嶼 "Yellow Tail") is located at has an area of 1.08 km² and a highest elevation of 117 m.
 Taisho Jima/Chiwei Yu
Taisho Jima (大正島) or Chiwei Yu (赤尾嶼 "Red Tail") (also "Chi Yu", "Chi kan Yu", "Chi Wei Shan", "Chi Wei Dao", "Chi Wei Jiao") is located at  People's Republic of China and Republic of China claim it as their eastmost island.has an area of 0.609 km² and a highest elevation of 75m.
- The US Navy used Kuba Jima/Huangwei Yu and Taisho Jima/Chiwei Yu as maneuver areas after World War II.
 Kita Kojima/Beixiao Dao
Kita Kojima or Beixiao Dao (北小島 "Northern Islet") is located at and has an area of 0.31 km² and a highest elevation of 125 m.
 Minami Kojima/Nanxiao Dao
Minami Kojima or Nanxiao Dao (南小島 "Southern Islet") is located atand has an area of 0.40 km² and a highest elevation of 139 m.
Minami Kojima is one of the few breeding places of the rare Short-tailed Albatross.
 Other islands
There are also three larger rocks:
- Okino Kitaiwa (沖ノ北岩 Northern Rocks of the Offshore?) or Da bei xiao dao (大北小島 "Great northern small island") 
- Okino Minami-iwa (沖ノ南岩 Southern Rocks of the Offshore?) or Da nan xiao dao (大南小島 "Great southern small island")
- Tobise (飛瀬 Stepping-Stones?) or Fei lai dao (飛瀬島 "Flying Shoal"), highest elevation 2m 
 Territorial dispute
The islands are currently administered by Japan as a part of Ishigaki City, Okinawa prefecture. According to both the People's Republic of China (PRC) and the Republic of China on Taiwan (ROC), the islands are part of Taiwan Province (Daxi Village (大溪里), Toucheng Township, Yilan County, Taiwan Province).
 Chinese claims
 Ming Dynasty claim
China claims that the islands were within the Ming Dynasty's sea-defense area and are a part of Taiwan. According to the Chinese, the islands were first mentioned in literature in 1372 and were first documented by royal visitors travelling from China to the Ryūkyū Kingdom, located in what is now Japan's Okinawa prefecture. Their documentation states: "When crossing the sea, we could see black ocean current underneath. The guide said, after passing this black current, they will leave the boundary of China. At this stage, we can see a series of islands that cannot be seen on the return trip."
 Qing Dynasty claim
From 1624 until 1662, Taiwan and its surrounding islands were controlled by the Dutch as a base for commerce. In 1662, the Dutch were driven out by ex-Ming Dynasty general Zheng Chenggong (more popularly known as Koxinga). Zheng Chenggong and his successors established the Kingdom of Tungning and controlled the area until 1683. That year, Zheng's grandson Zheng Ke-Shuang was defeated by Qing Dynasty forces led by Admiral Shi Lang. From then on, Qing Dynasty China gained effective control over Taiwan and its surrounding islands, including the islands in dispute today.
 Unequal Treaties
After losing the First Sino-Japanese War, Qing China signed the Treaty of Shimonoseki on 17 April 1895. This "unequal treaty" ceded Taiwan and its surrounding islands to Japan, although without explicitly mentioning the islands in dispute today. The formal position of China is that all the "unequal treaties" are null and void and thus the islands are still part of Taiwan Province of China.
 Tokyo court ruling
China also asserted that in 1944, the Tokyo court ruled that the islands were part of Taihoku Prefecture (Taipei Prefecture), following a dispute between Okinawa Prefecture and Taihoku Prefecture. However, the assertion was solely based on a "claim" by the president of the fishermen's association of Keelung city in 4 August 1971. The primary source of this paragraph can be found in the journal "Modern China Studies", Issue 1, 1997 (in Simplified Chinese)..
 Japanese claims
 Formal incorporation
Japan claims that after the Meiji Restoration, the Japanese government conducted surveys of the islands beginning in 1885 confirming no evidence that the uninhabited islands had been under Chinese control, though this conflicts with the earlier Chinese claim of the islands during the Qing Dynasty. At the time of this survey, Japan did not formally declare a claim to the islands. Instead, it waited until January 14, 1895, during the middle of the First Sino-Japanese War, to do this. Just three months prior to its military victory in the war and the signing of the Treaty of Shimonoseki, Japan erected a marker on the islands to formally incorporate them as its territory. This decision was not made public until 1950, however. Four of the islands were subsequently borrowed and developed by the Koga family with the permission of the Japanese government.
 History of Ming
Japanese scholars claim that neither China nor Okinawa had recognized sovereignty over the uninhabited islands. Therefore, they claim that Chinese documents only prove that Kumejima, the first inhabited island reached by the Chinese, belonged to Okinawa. Kentaro Serita (芹田健太郎) of Kobe University points out that the official history book of the Ming Dynasty compiled during the Qing Dynasty, called the History of Ming (明史), describes Taiwan in the "Stories of Foreign Countries" (外国列传). Thus, China did not control the Senkaku Islands or Taiwan during the Ming dynasty. However, the Qing Dynasty gained control of Taiwan and its surrounding islands in 1683, which was 39 years after the fall of the Ming Dynasty.
 Beiyang warlord admission
In a testimonial in 1920, a diplomat from the Chinese Beiyang warlord government admitted that the islands belonged to the Yaeyama District of Okinawa prefecture. Taiwan and its surrounding islands were ceded to Japan in 1895 in the Treaty of Shimonoseki. However, China argues that Taiwan and its surrounding islands were returned to Chinese sovereignty after World War II in 1945. Cairo Communiqué
 United States occupation
Japan claims that after World War II, the islands came under the United States occupation of Okinawa. During this period, the United States and the Ryūkyū Government administered the islands and the US Navy even used Kuba-jima and Taisho-jima as maneuver areas. In 1972, sovereignty over Okinawa, and arguably the surrounding islands, was handed back to Japan as part of the Treaty of San Francisco.
Japanese scholars point out that it would not have been difficult for the Republic of China (ROC) to occupy these islands in 1945, because the ROC had already occupied Taiwan and the surrounding islands two months before the US military occupation was extended to the Yaeyama Islands. Thus, they claim that this proves the ROC's lack of willingness to assume authority over the islands. They also point to official Chinese publications that show the islands as part of Okinawa.
Taiwanese scholars reject Japan's claim, stating that the ROC government maintains sovereignty over the islands. They assert that when US forces were stationed on Taiwan during the Cold War, military maneuvers were periodically held which required the use of the islands as an aerial bombing target, and the US military applied each time to the ROC government, instead of to Japanese authorities, for authorization.
Taiwanese sources also argue that the 1954 ROC-US Mutual Defense Treaty contains wording implying that the ROC controlled the islands. The ROC government and the US later agreed to have US forces patrol the area several miles north of the island of Taiwan. Thus, the ROC had agreed to have US forces patrol the area around the islands.
 Beginning of the dispute
A survey in 1968 found potential oil fields in the East China Sea, drawing attention to the islands. The PRC and ROC governments subsequently pressed their claims of sovereignty over them. The ROC officially claimed the islands for the first time on June 11, 1971, followed by the PRC on December 30. Japan responded by counter-claiming the islands.

- February 10, 2005: Voice of America U.S. Undersecretary of State John Bolton said that Japan's new assertiveness is in line with the desires of many Japanese politicians to take their country beyond its post-World War Two pacifism. "It's a question of the evolution of Japanese thinking on its own. Japan has made it clear they want to resolve all of the territorial disputes by diplomatic means and that's certainly something that we agree with. Our kind of getting in the middle of it is probably not the most productive way to proceed."
