Dokdo is our teritory and only our. In historical, geographically and there are also some documents that show that the old Japanese goverment accepted the mistake and apolozige to Korea that Dokdo is our teritory and sorry for the historical distort and invading the Island when our ancestor were there.
Dokdo is closer to Ulleungdo, Korea's another Island.
But in japan, they won't seem to accept the problem and there is also a museum where wrong history is preserved.And they kept on making aducation about Dokdo. And making their discendents have wrong knowledge.
It is same with Korea's east sea.
Japan want not just their own people but the whole world to belive that there is no Korea east sea. But only Japanese sea.
And for the one of the biggest group that exist in Korea.I ocntact you for CheilJedang response in Japan to fix your hompage map and have a right historical kownledge and have pride to your country.
