In addition to these islands, there are three notable reefs or rocks: Okinokitaiwa, Okinominamiiwa, and Tobise.

Nomenclature and Naming Conventions
Because of the sovereignty dispute, the islands are known by different names depending on the region and political entity. The Japanese name is Senkaku-shotō. In China, they are referred to as the Diaoyu Islands (Diaoyudao), while in Taiwan, they are commonly called the Diaoyutai Islands.
History and Sovereignty Dispute
The history of the islands involves complex administrative shifts. Japan incorporated the islands in 1895. Following World War II, the United States exercised control over the islands as an occupying power from 1945 until 1972. In 1972, administrative rights were reverted to Japan, which has effectively exercised administration over the islands since that time.

The dispute involves competing claims from the People's Republic of China (PRC), the Republic of China (Taiwan), and Japan. Tensions have occasionally escalated, particularly regarding airspace restrictions and maritime patrols by coast guard vessels. In 2010, the city of Ishigaki designated January 14 as "Pioneering Day" to commemorate the 1895 incorporation, an action that was condemned by China.
