In the map shown in the website, I can see there is a word that expresses the sea between the Korean peninsula and Japan called "Sea of Japan". However, I think this expression should be changed to "East Sea" because the word "Sea of Japan" is a word that was made by the imperialism of Japan. So it is not a right expression to explain the "East Sea"
It maybe just a mere expression mistake, but I think it's right to change something that is wrong. I humbly ask you to change the word "Sea of Japan" to the "East Sea", and if you don't mind, give me a reply email to sjb011016@naver.com
Thank you again for reading this, and I will wait for your contact^^
Yours sincerely,
