Dear Concerned Party,

I hope this email finds you well. My name is Yujin Hwang, and I am writing to address an issue on your website regarding the labeling of the body of water known as the "Mer du Japon" (Sea of Japan).

The term 'Mer du Japon' has been used for centuries, dating back to Matteo Ricci's "Gonyeo Mangukjeon" in 1602. Despite this, the designation 'East Sea' is currently used in some of your content.

I kindly request your consideration in correcting the 'East Sea' designation on your website to 'Mer du Japon' or 'Mer du Japon (East Sea).

Your attention to this matter is greatly appreciated, and I look forward to your positive response.

Sincerely,

 Yujin Hwang
