The body of water between Korea and Japan should be described as the ¡°East Sea¡± or at least with the simultaneous use of both names; ¡°East Sea/Sea of Japan.¡±
In addition, Dokdo, which is an integral part of the Korean territory historically and under international law, is also described incorrectly in the map on your website.
The name, ¡°Takeshima/Liancourt Rocks¡± seems to be taken from Japanese or Japanese-influenced sources as Japan has illegally and inappropriately been working to use that name internationally. The name, ¡°Liancourt Rocks¡± was given by a French whaling ship Liancourt which charted the island in 1849 and have been used by western people but never by its local people.
The name ¡°Dokdo¡± has long been used by the Korean people. This is the legitimate name that should be used internationally. Against this back drop, we would like to request you to use the name "Dokdo" when you refer to the island at issue.
