First of all, it is clear that the East Sea is not Japan's territorial sea, but Korea's territorial sea, in the old maps and old geography books of Korea and Japan. Through this, it can be seen that historically, the fact that the East Sea is a territorial sea of Korea has already been proven and is a clear truth that no one can deny.
Second, if you don't fix these errors properly, it can have a negative impact on future generations. It poses a great risk that can instill misconceptions in future generations and even lead to historical distortion.
Finally, it can be confusing globally. If someone sees your site and recognizes that the Sea of Japan is marked as Sea of Japan, and keeps that perception as basic knowledge, it will lead to the rapid spread of that knowledge around the world.
Therefore, I want you to quickly recognize and correct errors on your site. If you correct errors, you contribute not only to a positive impact, but also to instill correct values for history.
