Actually, it is in dispute what word would be correct ¡°East Sea¡± or ¡°Sea of Japan¡±. Throughout the history, ¡°East Sea¡± would be more correct because ¡°Sea of Japan¡± is related with the period of imperialism but, currently UN recommends describing the water between Korea and Japan using both words, ¡°East Sea¡± and ¡°Sea of Japan¡±, at the same time.
Therefore, I would appreciate if you revise your article by changing the word ¡°mar de Japon¡± into ¡°Mar Oriental¡± or at least using both words at the same time.
hope that errors in your website will be corrected as soon as possible. If you don¡¯t mind, you can get more information about Dokdo by visiting the site (http://www.mkoreadokdo.com/). It would be very useful if you reference this site because it revise many errors about Dokdo. But I¡¯m afraid that all articles written in Korean. If you want, you can e-mail to me for any questions.
Thank you again for you help. I¡¯m looking forward to hearing from you.
