What I found is that the sea between Korean peninsula and Japanese peninsula name is described as a wrong name, Because the Sea is close to both Japan and Korea, many people misunderstand the actual name of the Sea. The name of the sea should be 'East Sea' which has been used since Korean emprie dynasty. According to UN, they suggest to state the name of the sea 'East Sea' or 'East Sea/Sea of Japan'.
Finally, thank you for spending your precious time on reading long letter. And if you don't mind could you let me know the email address of the person in charge of any possible way to fix this flaw? (My email address is bhlim1016@gmail.com) Thanks again and have a good day.
Sincerely Yours,
Bohyun Lim
