Dokdo (Takeshima)/Debate Guide
Korea claims territorial sovereignty over Dokdo based on historical control of Dokdo beginning with the conquest of Ulleungdo by Shilla in 512 A.D. and subsequent de facto control based on visibility from Ulleungdo, which is the nearest historically inhabited Korean island from Dokdo. Japan claims territorial sovereignty based on activities including fishing and felling of bamboo groves at Dokdo from mid-17th century on. Korea claims that prohibition of seafaring to this area since 1696 by the Japanese government applied only to Ulleungdo, while Korea maintains that the ban applied Ulleungdo and appurtenant islands including Dokdo. Many maps, both Korean and Japanese, before 1905 show Dokdo as a Korea territory. On January 28, 1905 during the Russo-Japanese war, Japan issued Shimane Prefecture Notice No. 40 that incorporated Dokdo as a Japanese territory under the claim of terra nullius. The Korean government was not notified until March 29, 1906, well after Japan defeated Russia and concluded, on November 17, 1905, the Eulsa treaty that made Korea a protectorate of Japan amd prevented Korea from lodging any protest against the Japanese action over Dokdo.
