Dokdo island belong to Korea since Shilla Dynasty in 512AD and even Japanese treated it as a Korean territory.

Dokdo belong to Korea since 512AD and was accepted and treated by Japanese as a part of Korean territory until 1953. Sudden change of the opinion after so many years is just an attempt to expand Japan territory consisting only island, what can proof the conversation also about islands with China and Russia. Since Dokdo was treated, accepted as Korean territory for such a long time, where is any trace any tangible proof that Dokdo belonged to Japan earlier than 19th century or 512AD? Maps from many countries until the 19th century labeled Dokdo as territory of Korea. Same as Korea-Japan annexation period (1910-1945) classified Dokdo as a part of Korea.
