The Senkaku Island represent one of East Asia’s most enduring territorial disputes.

The islands comprise Uotsuri Island, Kuba Island, Taisho Island Kitakojima Island, Minamikojima Island, Tobise Island, Okinokitaiwa Island, and Okinominamiiwa Island.

Located in the East China Sea approximately near from the Chinese coast, these five uninhabited small islands and surrounding rocks have become a flashpoint for competing claims of sovereignty among Japan, China, and Taiwan, with significant implications for regional stability and global great-power competition.

 Geographic and Strategic Significance

• The largest island, Uotsuri, covers only 1.4 square miles, yet these islands hold considerable strategic value. Located strategically in the East China Sea, they are believed to sit atop hydrocarbon (oil and natural gas) reserves, though these have not yet been proven/extracted.
• More significantly, from a military perspective, control of the Senkakus would provide enhanced surveillance capabilities over the East China Sea
• The islands are situated within the US- Japan security treaty framework meaning that Article V of the Treaty of Mutual Cooperation and Security applies to them—obligating the United States to defend the islands if attacked.​

Legal argument

First Sino-Japanese War and the Treaty of Shimonoseki (1895)

Japan’s position rests on surveys it conducted from 1885 onwards, culminating in a formal Cabinet Decision on January 14, 1895, to incorporate the islands into Okinawa Prefecture as terra nullius (land belonging to no one). Japanese authorities argue that the islands were uninhabited with no evidence of prior Chinese control, and that Japan maintained administrative continuity. ​
