"The Sea Of Japan was written  400 years , East Sea written 2000 years.

History says "East Sea" is correct.

Geographical names contain history and culture.

The nomination "East Sea", 「 In Samguk Sagi 」 dongmyeongwang (59 BC) side of Japanese source of the Sea of Japan, which first appeared in nomination the name of a country about 700 years earlier than the emergence of.

In addition, Goguryeo was named East Sea. China said that King Gwanggaeto, the rain (414), sinjeungdonggugyeojiseungnam 「 of Eight State Map, 」 (1531), yeojido 「 this country gun 」 (the late 18th century,), and much more will appear in the nation's food.

Japanese literature can not be found even before the end of the 18th century, even in the Sea of Japan nomination also be marked on maps that refer to the sea. The history of the 25 years, compared to the name East Sea, which have been used - Sea Of Japan nomination a very short.

Thank you for your attention, as this is a huge concern that should not be overlooked. 

I would be looking forward to hear from you.

Please read this letter and make the correction.
