In your website, you used the map showing South Korea and Japan. In that map, the "East sea" was described as ¡°the Sea of Japan¡±. The body of water between the Korean peninsula and the Japanese archipelago should be put as "East sea" in that it is currently the territory of Korea.
I hope you will make corrections in the map and use 'East Sea' to describe the body of water between Korea and Japan.
Thank you for reading and we would appreciate your favorable consideration.
Yours sincerely,
Hye Jin Jeon
