<i>Isotakeshima Oboegaki</i> and Japan’s Confirmation of Dokdo as Korean Territory in the Late Seventeenth Century
Bibliographic record
Abstract
The Japanese Ministry of Foreign Affairs officially claims that Japan had discovered Takeshima (Dokdo) since the seventeenth century, but this article argues that quite to the contrary, Isotakeshima Oboegaki, a primary source that confirms Japan’s recognition of Dokdo as Korean territory, clearly corrects this claim. Isotakeshima Oboegaki’s importance can be explained in three ways. First, Japan’s official position regarding Dokdo wrongly conflates different uses of “Takeshima” depending on historical context and ignores that it was because of a paucity of Japanese sources confirming Japanese ownership over Takeshima (Ulleungdo) and a comparative certainty from the Korean government, forcing a reluctant Bakufu to admit the deficit in historical evidence and order that Japanese fishermen cannot trespass into Ulleungdo. Second, Isotakeshima Oboegaki was not just a document of its time but a key primary source that the Meiji government invoked as undeniable evidence to officially declare in the Dajokan Directive that neither Dokdo nor Ulleungdo were under Japanese sovereignty due to a paucity of evidence. Finally, Isotakeshima Oboegaki terminates Japan’s logic regarding Dokdo because it contradicts the Japanese Ministry of Foreign Affairs’ claim of “original discovery” regarding Dokdo and Ulleungdo and corrects the mistaken notion of terra nullius.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
