Dokdo is the territory of Korea, located at 135th meridian east, 37 ¡Æ north latitude.
Korea's record of ruling over Ulleungdo and Dokdo can be first found in the <Chronicles of the Three States>, an ancient book written in 1145.
And until now, Korea has recognized Dokdo as our territory and continued to exert sovereignty over it.

Also, considering the historical legitimacy of the name of the East Sea, the topographic characteristics of the East Sea waters, and the international norms on geographical names ect., it is right to use the name of 'East Sea' of Korea and 'Sea of Japan' of Japan together.
So we thought that equal opportunity must be provided to the ¡®East Sea¡¯ when doing activities like searching for the location of particular area on the map.
Actually, ¡®East Sea¡¯ is the appellation which has started to be used 700 years before the appearance of the nation named ¡®Japan¡¯.
For people who don't know much about this, it can be viewed that the real appellation of the area is not the ¡®East Sea¡¯ but the ¡®Sea of Japan¡¯, owned by Japan alone.
