With all due respect, I am writing this letter to you concerning the misleading maps contained in your website.

To my great surprise, in this map, the ocean that is located between the Korean peninsula and the Japanese archipelago is named the "Sea of Japan," not the "East Sea."
As a conscientious high school student who has a certain degree of historical and geographical knowledge about what is right and wrong, and as a Korean national who is fully aware of how the East Sea is enthusiastically beloved by our people, I could not help but write this letter to you.
