Hi. I am “Noh seowon”, a high school student who is active in protecting “Dokdo” and “East Sea” in Korea.

I am working to protect our territory and territorial waters from Japan and to be recognized by the international community.

I am sending an e-mail because I found a part of your website where “East Sea” was incorrectly marked as “Sea of Japan”, explaining its historical background and asking for the correct notation in articles after this time.

‘East Sea’ is a name that has been used by Koreans for over 2,000 years, and this can be confirmed in various historical sources and old maps.

On the other hand, the name 'Sea of Japan' is claimed to be the first name used in Matteo Ricci's "Gonyeo Mangukjeon" in 1602. It is proven through various feeds. In particular, Japan presented the results of an ancient Western map survey indicating that the use of the'Sea of Japan' increased in the 19th century, and claimed that the name'Sea of Japan' was established in the 19th century. The fact that a number of maps made in Japan at the time marked the East Sea waters as “Sea of Joseon” shows that the name “Sea of Japan” was not established even in Japan.

'East Sea' has been used for more than 2,000 years, and is still used by 75 million Korean people, and has an important meaning to us as it appears in the first verse of the national anthem. Nevertheless, unlike Japan, we do not insist on the use of ‘East Sea’ alone instead of ‘Japan Sea’, and we are presenting a rational way of stating the names used by both sides together.

Therefore, the'Japan Sea' displayed on your website should be written as'East Sea' or'East Sea (Japan Sea)'. Please correct the incorrect notation in this article, and make an effort to make it correct when writing future articles. We look forward to your response.

Wishing you endless prosperity...Noh Seowon
