To whom it may concern,  

Hoping this email finds you well, I am Hyeseung Ko, and I am a highschool student in South Korea.  

First of all, I would like to thank you for providing useful information.  

However, I sent this email because I found an error within your work. 

Currently, I have been participating in a campaign in which participants correct clerical errors of Dokdo and East Sea/Sea of Japan in the Internet.

While researching for an assignment, I found out that the name of area to which North Korea launche a missile is mentioned as Sea of Japan.

According to the resolution made in UN and other international organizations, the appellation of a shared geographical feature must be written side-by-side if the countries directly involved cannot make settlement.

Therefore, the proper designation method of the area is East Sea/Sea of Japan. since there has been no consent between South Korea and Japan regarding it.

In case you want some references for further understanding, I also attached a website link that explains about this matter.

Besides, I hope this email will feed into your journal, and I would appreciate if I can get a reply once you check this.

Thank you and have a wonderful day.

Yours Sincerely

Hyeseung Ko
