In the Map of Joseon, new version (1894) made by the Japanese, Ulleungdo and Dokdo are marked in yellow color as Korean territory, while the Kyushu region is colorless. Before 1905, most maps of Japan and Joseon produced in Japan indicated Dokdo to be Korean territory.

In March 1906, the Korean Empire issued its 3^rd Directive: announcing that Japan’s Dokdo dispute was groundless and ordered Gangwondo Province to keep an eye on Japanese behavior. Korea thus verified that Dokdo was Korean territory.

 In March 1906, Japanese governmental officials of Shinema Prefecture inspected Dokdo, before visiting Ulleugdo to tell governor Shim that Dokdo, being incorporated into Japan, vore the new name Takeshima. Governor Shim then made a report to Gangwon-do Province that ‘Our county territory Dokdo’was incorporated into Japan. His report is the first mention of Dokdo in Korean literature, claiming Dokdo as part of Uldo-gun. 

 Tadataka Ino created an official map of Japan after surveying the whole of Japan for approximately 20 years. At that time, Dokdo was excluded from the land survey and records of Japanese territory. 

Ah Yong-bok, lost direction on his second trip to Japan in May 1696, and found himself in the Oki Islands. Upon examination by government officials, they raised no objection to his statement that Jukdo (Ulleungdo) and Songdo (Dokdo) belonged to Gangwon-do Province, and recorded it in their report. This demonstrates that Oki Islands government officials accepted the claims of Dokdo as Joseon territory.
