I was really touched by your positive reaction toward my suggest. I'm sure that your deep consideration will definitely help changing the distorted information that people have about East sea. The following address is the one with the name Sea of japan.

Actually I realized that the map includes chinese character which is used in both Japan and Korea and it is hard for foreigners to understand chinese character. The chinese character(日本海) marked in the map of East sea means Japanese sea. East sea's chinese character name is 東海, which just means east sea. 

Again, I deeply thank you for your reply which had given me a lot of positive energy.

Yours faithfully, 김해정.
