Dear Who in charge of Feedback

Hello, I’m a high school student of Hana Academy Seoul, in the Republic of Korea. Thank you for the news on North Korean ballistic missile test at below URL.

However, while I was watching and reading this news I found something wrong about ‘Sea of Japan.’ Your news marked ‘Sea of Japan’ instead of ‘East Sea’. It’s wrong to mark only ‘Sea of Japan’at least 2 times. Also a woman reporter in Beijing talked about the news that she uttered Sea of Japn too. According to international organization, “If each two of two or more countries use different name, international organization advises the name’s simplification, and if it can’t do, it has to use both names.” Since Korea and Japan haven’t discussed name’s simplification ‘Sea of Japan’ has to be marked with ‘East Sea’.

Therefore, I humbly ask you to change ‘Sea of Japan’ into ‘East Sea’ or at least mark both names into that news. Thank you for your help. I look forward to hearing from you via my email sechan10121@naver.com

Yours sincerely,
Sechan Lee
