In our historical records, Dokdo first appeared under the name Usando is in 1454. Even if Dokdo was already recognized before that time, this is the first in historical records. However, in ancient Japanese documents, it first appeared under the name Songdo (áæÓö, Matsushima) in Eunju Cheonghapgi (1667) compiled by Saito Hosen. In other words, it is the fact that the historical recognition of Dokdo is at least 213 years ahead of Korea's record. In addition, in , it is stated that Japan's northwest limit is to this Oki Island. Dokdo, which is northwest of Oki Island, is excluded from the Japanese territory. These historical facts are an important basis for proving Dokdo is our territory.

At that time, and appeared to seize Ulleungdo in order to advance the continent of imperialism. The data of Shimane Prefecture and the government were reviewed by the Ministry of Home Affairs and the Ministry of Foreign Affairs, and finally, Taejeonggwan, the best political decision-making body at the time, said'Jukdo Oeildo', that is, Ulleungdo and Dokdo are not Japanese pandos. By issuing the Taejeonggwan Order, they concluded on the territorial issue. This is a definitive historical record of Japan's recognition of Dokdo as Korean territory.
