context_page_description: A dispute exists over the international name for the body of water which is bordered by Japan, Korea and Russia. In 1992, objections to the name Sea of Japan were first raised by North Korea and South Korea at the Sixth United Nations Conference on the Standardization of Geographical Names. The Japanese government supports the exclusive use of the name "Sea of Japan", while South Korea supports the alternative name "East Sea", and North Korea supports the name "Korean East Sea". Currently, most international maps and documents use either the name Sea of Japan by itself, or include both the name Sea of Japan and East Sea, often with East Sea listed in parentheses or otherwise marked as a secondary name. The International Hydrographic Organization, the governing body for the naming of bodies of water around the world, in 2012 decided it was still unable to revise the 1953 version of its publication S-23 – Limits of Oceans and Seas, which includes only the single name "Sea of Japan", to include "East Sea" together with "Sea of Japan".
  The involved countries have advanced a variety of arguments to support their preferred name.
context_section_description: To provide evidence for the date when Sea of Japan came to be used internationally, both South Korea and Japan have undertaken surveys of various historical maps.
  In 2004, South Korea surveyed ancient maps archived in the British Library, the Cambridge University Library, the University of Southern California (USC) East Asian Map Collection, the U.S. Library of Congress, the National Library of Russia, and the French National Library examined 762 maps.  They found that 440 maps had used Sea of Korea (Corea), Oriental Sea/East Sea, 122 had used Sea of Japan, and 200 had used other terms. In the French language, the word orientale includes both the meaning of "eastern" related to compass direction and the meaning of "oriental", the Asiatic region. The same ambiguity is present in the Russian language, with both "eastern" and "oriental" indicated by one word.
  From 2003 to 2008, Japan conducted a number of surveys of different collections. In 2010, the Ministry of Foreign Affairs (MOFA) published their conclusions; they found that among 1,332 maps from the Berlin Library, 279 used Sea of Korea, Oriental Sea, or East Sea (or some combination thereof), 579 used Sea of Japan exclusively, 47 used China Sea (with or without other names), 33 used another term, and 384 used no term. MOFA said the Struck collection (a collection of antiquarian maps owned by a European map collector) showed that out of 79 maps, 35 used Sea of Japan, 9 used the Sea of Korea, 2 used Oriental Sea, and 33 were unmarked. MOFA reported that among four Russian libraries and document archives holding 51 maps, 29 used Sea of Japan, 8 used Sea of Korea, 1 used Korea Strait, 1 used East Sea, 1 used Sea of China, and 11 used no name.  MOFA said that among 1,213 maps from the U.S. Library of Congress, ones that gave a name for this body of water showed that 87 percent used Sea of Japan, 8 percent used Sea of Korea, 5 percent used other terms, and none used Oriental Sea or East Sea. Similarly, MOFA said that 58 maps from the British Library and the University of Cambridge showed 86 percent used Sea of Japan, 14 percent used Sea of Korea, and none used Oriental Sea, East Sea, or other terms. MOFA said that they looked at 1,485 maps in the French National Library. They reported that 95 percent of 215 French maps used Sea of Japan.
  In November 2007, the National Geographic Information Institute of South Korea published a report on a survey of 400 ancient maps. According to the report, nine maps used East Sea for the water currently called Sea of Japan, while 31 maps used East Sea for the water currently called East China Sea. The number of maps that used Sea of Japan is not disclosed. Furthermore, the report says "In the late 18th century (1790–1830) the name Sea of Japan emerged. From the 19th century (1830 onward), there was a rapid increase in the use of the name Sea of Japan." Japan stated, "This clearly shows the fallacy of the ROK's assertion that the name Sea of Japan was the result of the Japanese policy of expansionism and colonial rule, and can be interpreted as affirming that the name Sea of Japan was in widespread use well before Japan's colonial rule over the Korean Peninsula".
