First, the East Sea is the territorial sea of Korea. The East Sea is not the Sea of Japan. As the sea that surrounds the east of Korea, it is the territorial sea of Korea. Therefore, the title of this article and the history of the East Sea are wrong.
Second, the history of the East Sea is wrong. Donghae has been our territorial sea since ancient times. Also, even when Japan was liberated because it made Joseon as a colony, the territorial sea was not Japan.
The third is Korea's position. It was said that the Republic of Korea is falsely claiming that Japan's territorial sea, the Sea of Japan, is its territory, but this is not true. In the first place, it is Japan that covets our territorial waters. Japan is coveting the East Sea and Dokdo Island on the basis of absurd grounds, but our Republic of Korea has never tried to take Sea of Japan.
