I really loved your youtube and I still love yout content.

However, In your video there is a big error that I want to ask about. 

If you can see, your picture has a mark of 'Japanese sea' in the world map where there suposed to be 'Korea east sea'.

When I first saw this problem, I really had to contact you about this matter and conviced you to change your mind and change your picture of Japanese sea. 

In the first half of the 20th century, Japan robbed Korea of its national sovereignty. Korea was deprived of the opportunuity to make the name, 'East Sea', known to the world. How long has the name "East sea' used.

According to the Chronicles of the Three Kingdoms, published in 1145 AD, the name, " East Sea" was used as early as 59 BC. As confirmed by the Monument in memory of a great Korean King in the 5th century, and numerous other references that followed. It means that Korea has used the name, "East Sea" for over 2000 years. 

However, Japan argues that the term, Sea of Japan was established in the 19th century. 

Surprisingly, official Japanese maps produced up unitl the late 19th century. 

We Korean's can't just let this happen. 

So we are contactiong you for your help. `

I gave you an youtube address for more information about Dokdo and Korea east sea.

And if you look at this. it would be a great help for both Korea and Japan and for your more information.

I wish you more luck and Thank you!

Sending Love (Love you!)
