Who ever says that dokdo and the East sea is Japan's??? You know, as I always did to my friends and relatives, I'll explain all of it
To start with, we have to go to the history. There were some prisoners and crimes in Korea that time. Dokdo, the island in the East sea's wave was tough and nobody will ever imagine to go there. So the crimes went there and that annoyed the king that time so the king orders servants to empty the island. AFTER THAT HAPPENS, Japan goes to Dokdo and claims "We found it first!" and then a commoner, An Yong Bok gets mad and pretends to be a high cheif. Goes to Japan and claims it. The (real) cheif in Japan listens to him and says "Okay then calm down, we ADMIT that Dokdo is Korea's" so Yong Bok returns to Korea. AFTER THAT ONE JAPAN DOES THIS AGAIN!!!!!! AND AGAIN!!!!NEVER ADMITS!!!
After 300 or more years later Japan teaches kids that KOREA is being a fool and doesn't admit. Koreans, who were under control Japan they freed themselves by shouting independent
