The purpose of this study is to trace the origins of the “Takeshima Day” ordinance in Shimane Prefecture, Japan. The discussion focuses on the period before and after the establishment of the ordinance in Shimane Prefecture in 2005, limited to the period of transition from a fishing issue to a territorial sovereignty issue in the contentious structure of the Japan-Korea relationship, since the entry into force of the UN Convention on the Law of the Sea in 1994. The issue of Takeshima in Shimane Prefecture began with the assertion of territorial sovereignty for the fishing rights around Dokdo. The justification for modifying related policies in a direction that takes an active and proactive role in making noise about the Takeshima territorial dispute was found to be closely related to institutional changes, such as changes in the Japan-Korea fisheries regime, the introduction of fishing quotas, and the expansion of the influence of local NGOs. In this way, the fundamental reason why Shimane Prefecture raised the territorial sovereignty issue through the establishment of the “Takeshima Day” ordinance was the fishing problem for securing its survival. Japanese coastal fisheries, especially those in Shimane Prefecture, showed a rapid decline in catch volume starting in 1998, and there were continuous demands for a solution to the survival problem due to the economic impact on fishermen resulting from the conclusion of the new Japan-Korea fisheries agreement. To overcome these problems, Shimane Prefecture argued that it was necessary to establish territorial sovereignty to secure safe fishing rights in the provisional waters around Takeshima. The logical basis for this was that Shimane Prefecture's fishermen, who have a higher proportion of fishing, believed that if they could secure the Takeshima territorial sovereignty, they could increase their catch volume through securing new fishing grounds. In other words, the fundamental reason why Shimane Prefecture was able to establish the “Takeshima Day” ordinance can be traced back to the fishing problem rather than the territorial sovereignty issue.
