evidence: The Dokdo Islands (Takeshima, in Japanese) are a group of sea features located in the Sea of Japan (also known as East Sea). The features are controlled by South Korea and disputed by Japan. Composed of two islands and 89 surrounding islets, the total area of the group is approximately 187,000 square meters. The two main islands, Seodo (West Islet) and Dongdo (East Islet), host a number of structures such as a docking facility, a heliport, and living facilities. Dokdo is located over 87 kilometres southeast of the nearest Korean island, Ulleungdo, whereas the nearest Japanese island (Oki) is located more than 157 kilometres to the southeast. Designated as state-owned land, Dokdo and its surrounding waters are patrolled by the Dokdo Coast Guard and Korea Coast Guard vessels. Other than the Coast Guard, several lighthouse staff and local government officers, Dokdo is also home to a number of civilian residents. [...] Bukh, Alexander. 2015.
