Hi, I am a student from South Korea.

I sent this email because I thought that there should have been errors fixed in your website.

The name "Sea of Japan" is not quite right. "Sea of Japan" should be fixed to "East Sea".

The name "Sea of Japan" is wrong. The territory and land in  which the name you used "Sea of Japan" is not Japan's territory. It is South Korea's territory. This evidence can be found in many places. So, if you have any questions, I recommend you to search for evidence. I sincerely ask you to change the name of the Sea for accurate information for people looking at your website.

I hope you fix the name of the Sea. Thank you for your cooperation.
