Abstract

The study examines Masatomi Uchikawa’s 1966–67 espionage case. A co-optee employed by Japan’s semi-governmental World Political and Economic Research Council (WPC/PRC), subcontracted to the Cabinet Intelligence and Research Office (CIRO), Uchikawa shifted from open-source analysis to covert operations in the Soviet Far East, where aggressive reconnaissance conflicted with his civilian cover, leading to arrest and imprisonment. Using Co-optation and Principal-Agent theories, the research shows Japan’s post-war intelligence fragility, institutionally constrained intelligence capability, and reliance on non-professional operatives. The case exemplifies governance failure: political priorities over operational security, exposing co-optees when plausible deniability fails, offering enduring lessons in tradecraft and accountability.
