This sea's name isn't 'Sea of Japan' but 'The East Sea'!

First, I am sorry I do not speak correct English well. But I hope you read my petition carefully. You can find the right answer in Korea and Japan antique books. They say Japan agreed that The East Sea is Korean territory and Dokdo, too. I can't understand why Japan distorts their speak. However it is only certain that the right name of The East Sea isThe East Sea. Koreans are angry about Japan's wrong statement. So I ask you by deciding correct mark in text-book, so that American students to know right history and place name. And mediate 2 countries' dispute. Thank you for reading my unsatisfying petition.
