The Eastern Sea has forever belonged to Korea! It is a shame for the Japanese country to insist that this is false!

I strongly declare that my country, Korea, has been the rightful owner of the Eastern Sea (and whatever lands within it, such as Dokdo Island) as long as I have lived and known of it.
My fellow Koreans and I have been put to shame and severely offended upon learning that Japan resorted to profaning this known-fact (for hundreds of generations), by claiming that the East Sea was actually their property! -unexpectedly, and seemingly out of the blue.
I do not know what others have decided to perceive from this altercation, but I am writing this in vehemence and hope that the Korean country will not be stripped of a mere bona fide capital.
I am not fighting due to the common bias that the old generation Korea carried against Japan, but solely to fight for simple morality. Thank you.
