At wikipedia page that describes the area between Korean and Japan, there is an erro that the body of water which lcoates between the Korean peninsula and Japan is mentioned as Sea of Japan.
As you know, there has been a long dispute between Korea and Japan regarding the name of sea. In other words, how the name of location is a very sensitive issue. According to the resolution made in UN and other international organizations, the appellation of a shared geographical feature must be written side-by-side if the countries directly involved cannot make settlement.
Therefore, as a member of the campaign I urge you to use the proper designation method of the area, which is East Sea/Sea of Japan. It is because there has been no consent between South Korea and Japan regarding it. To read full sentences of these gists, please visit this website at:

Once Korea and Japan agree on a common designation, that is in accord with the general rule of international cartography, we will then follow the agreed-on designation.
