Japan institutionalizes drone warfare amid manpower crisis and regional threat

Japan has formally established two dedicated unmanned systems offices within the Ground Self-Defense Force, backed by a ¥1 trillion ($6.3B) five-year procurement plan for thousands of drones across all service branches. The structural driver is dual: lessons from Ukraine and the Iran war demonstrating drone effectiveness, and a shrinking domestic workforce making manpower-intensive force structures unsustainable. Japan is explicitly targeting multi-domain unmanned capability (aerial, ground, surface, subsurface) with strike roles, representing a constitutional and doctrinal threshold crossing that reshapes the regional military balance vis-à-vis China.
