Using a proper name for the water between Korea and Japan is not simply a question of changing the name of a geographical feature. It is part of the national effort by the Korean people to erase the legacy of Japanese Imperialism and to redress the unfairness that has resulted from it.
It is an absoulte mistake to hear just one side of the story and to blindly follow. If we leave these kinds of things alone. It causes serious problems that disturb the order of international society.
Therefore, I urge you to use 'East Sea' to describe the body of water in question or to use both Korean and Japanese designation simultaneously in your contents and maps.
Once Korea and Japan agree on a common designation, that is in accord with the general ruleof international cartography, we will then follow the agreed-on designation
