please take a look at these maps.

http://www.freeworldmaps.net/asia/japan/index.html
One is map of korea and the other is map of japan.
Though it is same sea, one is written as "East sea" and the other is written as "Sea of japan".
during the 19th century, as Japan's power got bigger, Foreign people began to call "East sea" to "sea of Japan".
But this is wrong. There was no reason to call it "sea of japan".
I am a Korean high school student and a member of Dokdo cyber press.
You must be the one who is able to correct these errors.
Thank you.
yours sincerely,
