Dear webmaster,
Hello. This is Lee Yoo Seung, who studies oceanography in South Korea high school.
I have searched about ocean in Korea to learn about marine environment, using your website. I really thank you for your website which provides useful contents for my research. 

However, I have found a wrong information in your website from other sources during the research. In the map of your website, the name of the sea between Korea and Japan is described as "Sea of Japan". It seems unreasonable to use the name "Sea of Japan" which is decided in the period of imperialism because its original name is "East Sea" which has been used throughout history. Therefore, I believe that  the sea which is placed between Korea and Japan should be described as the “East Sea”.
