Injustice of Designation of East Sea of Korea as "Japan Sea" (2)

Pyongyang, September 8 (KCNA) -- Prof. and Dr. Jo Hui Sung, director of the History Institute of the Academy of Social Sciences, contributed the following article laying bare the injustice of changing the name of the East Sea of Korea into "Japan Sea":
After the signing of the "Ulsa Five-point Treaty" in 1905, the Japanese imperialists began to mark "East Sea of Korea" as "Japan Sea" on maps. In 1929 Japan began to mark the East Sea of Korea as "Japan Sea" with a meeting of the International Hydrographic Organization as an occasion.
The sea east of Korea had long been called either "East Sea of Korea" or "East Sea" worldwide.
Typical examples are a map attached to "Mongolian travelogue" (1245-1247) written by an Italian who traveled Central Asia in the 13th century, "Asia map" drawn by a Portuguese cartographer in 1615 and "East Asia map" published in Britain in 1647.
Many countries began to call the sea east of Korea "Koryo Sea" (Korea Sea) according to practice. Maps published in Europe marked the East Sea of Korea as "SEA of COREA".
Typical historical facts include "Complete Map of Asia" published in Japan in 1794, "Sketch of Japan" published in 1809, "Whole Map of Islands" published in 1810 and "Map of Great Japan" in 1872.
A map which was published with a copper plate by Kageyasu Takahashi, astronomer in the era of Edo, Japan, was put on display at the Haejong Museum in Kyonggi Province this year. On this map the East Sea of Korea was marked "Korea Sea". There are plenty other historical Japanese maps and data in which the East Sea is marked "Korea Sea".
