In your site, there is an article which the headline is < Kids in S. Korea mount postcard campaign over disputed isles> And there is a map. And it is telling us that the sea between Korean and Japan is ¡°Sea of Japan¡±. In the middle of the sea there is an island and it is called¡± Takeshima¡±. Many people were confused with these names, but it is not the fact. The correct name of those two are ¡°East Sea¡± and ¡°Dokdo¡±.
Japan contends that the island is Takeshima, not Dokdo, and even claims that the surrounding seas are all its territory. There is much evidence in Korea that Dokdo is our land. Korea has long insisted that Dokdo is our land. However, Japan is insisting on getting the sea around it.
