This cultural publication was produced in Japan for foreigners with an explanation of the East Sea. However, it contains incorrect information. As the first example, from the cover, it is expressed as 'the sea of ​​Japan', not the East Sea. Obviously, it is wrong to write ‘Japanese sea’, and it should be expressed as ‘Donghae’. Therefore, we request a correction to this expression. In addition, in addition to the countries that should be expressed as East Sea, most countries describe it as “the sea of ​​Japan,” and explain that this notation has been established. I don't think it is right to claim that they are marine territories without any evidence. I ask that these explanations also be corrected based on accurate evidence.

I am currently working as the Dokdo Reporter Group, and I am working hard to prevent typographical errors and false information, but there are numerous errors on the Internet or from other methods. Therefore, I want to tell people that we must selectively accept only the right information so that we can obtain the right knowledge and make accurate judgments. Correcting these errors can greatly affect people's perceptions. Thank you for reading the long article so far, and I look forward to a positive response.
