Irregular warfare and strategic adaptation in modern Japan: institutions, intelligence, and total war

This article examines irregular warfare in modern Japan as a strategic adaptation to late modernization, imperial competition, and total war rather than as a product of enduring cultural tradition. Using institutional and irregular warfare theory, it analyzes how intelligence, covert action, political warfare, and civilian mobilization developed from the Meiji Restoration through 1945. It shows that these methods emerged through organizational experimentation, bureaucratic rivalry, and geopolitical constraint rather than formal doctrine or historical continuity. By treating Japan as a comparative modern case, the article contributes to debates on strategic culture, state adaptation, and the escalation risks associated with deniable warfare.
