On 5 May 2012, the general assembly of the International Hydrographic Organization (IHO) stated a five-day conference in
with over 300 delegates from 80 members states. The meeting convenes once every five years. The South Korean delegate once again has pushed to add the name “ Monaco East Sea” for the waters separating the Koran Peninsula and . In early 1920s, Imperial Japanese government successfully registered the official name with the IHO as “Sea of Japan;” the term Japan Sea of Japan became widely adopted globally. According to the Japanese media no one except the US supports Japan’s position keeping the name of Sea of Japan (News Searchina. Ne.jp 26 April 2012). “As the meeting is held only once every five years, the power of the board of the committee is relatively strong,” a Foreign Ministry official said on condition of anonymity (Korean Herald 1 May 2012).”
