The occupation of Takeshima by the ROK is an illegal occupation without any legal ground whatsoever in terms of international law. No measure taken by the ROK during its illegal occupation with regard to Takeshima has any legal justification. Japan has consistently been making strong protests against each and every measure taken by the ROK and demanding the withdrawal of these measures.
Japan has proposed to refer this case to the International Court of Justice on three occasions since 1954. However, the ROK has rejected all of these proposals.
Korea is a most important neighboring country for Japan. In order to establish genuine, friendly relations between the two nations, Japan will continue to seek the settlement of the issue of Takeshima on the basis of international law and in a calm and peaceful manner.
