And they also make a mark Dokdo to Takeshima. 

Dokdo is obiously our territory, which has a lot of evidences. But Japan always claims that dokdo(takeshima; the name that japan called dokdo.) is theirs. 

 We can see their wrongdoing in their text books. Dokdo is distorted by Japan because of their text books and any other magazines. Consequently, young japanese have fallacy when they are young, and they will grow up and claim that of fallacy. It's vicious circle. 

 They must amend the wrong fact for international peace. Their argument is not only true but confusing to foreigners. What I want to say is Dokdo is truly our territory, not Japanese.
