Previously, South Korea had been pushing the IHO to recommend only using the term East Sea, but announced on 2 May 2011, that it now preferred the gradual approach of using both names now, and eventually dropping the Sea of Japan name.
此前，韩国长期推荐IHO只使用东海的称呼，但韩方于2011年5月2日宣布，它现在倾向于循序渐进的方式，先将两个名称共同使用，后面再慢慢去掉日本海这个称呼。
