In this video, I found an error in marking Dokdo as ‘Takeshima.’ 

As far as I know, the expression ‘Takeshima’ is an incorrect expression and should be corrected with the expression ‘Dokdo’. 

From now on, I will explain why it should be written as 'Dokdo'. 

Since there is a lot of historical evidence related to 'Dokdo', I will focus on the evidence from the geographic aspect. 

Geographically, Dokdo in the East Sea is 87.4 km from Ulleungdo and 157.5 km from Oki Island. 

Dokdo is visible to the naked eye from Ulleungdo, but not from Oki Island. 

These contents are also shown in 『Sejong Sillok Geography』(1454), an official book of the early Joseon Dynasty. 

When we see that historical records and geographical features match, Dokdo has long been a territory of Korea.

For the same reasons as above, I insist that Dokdo is Korean territory. 

If you don't understand or need more evidence, please contact me by email. 

Since there is a lot of evidence, it will be enough to help the web administrator understand. 

I would be grateful if the web administrator reads this article and corrects the error. 

Then, I look forward to the positive results. 

Thank you.
