This research analyzes how a series of Allied occupation directives (SCAPINs 677, 841, and 677/1) interacted with the drafting and implementation of the 1951 San Francisco Peace Treaty to shape the legal status of Dokdo Islands (Takeshima). The author argues that, first, SCAPIN 677 excluded Dokdo from Japan’s governmental and administrative control by defining “Japan” for occupation purposes and listing excluded areas. Second, Paragraph 6 clarified that this definition did not predetermine ultimate sovereignty. Third, SCAPIN 841 partially amended SCAPIN 677 by returning the Izu and Nanpo Islands north of and including Sofu Gan to Japanese administration. Fourth, SCAPIN 677 remained operative for other excluded areas, including Dokdo. This essay contends that Dokdo’s omission does not imply a Japanese title because its exclusion had already been implemented under SCAPIN practice and reflected in the UK draft. While SCAPINs did not themselves determine ultimate sovereignty, their unrevoked administrative separations were “inherited” by the San Francisco framework.
