Japan accelerates security document revisions to address AI and drone warfare

The Japanese government is accelerating the revision of its three core national security documents, aiming for completion by the end of 2026. This move, led by Prime Minister Sanae Takaichi, seeks to address rapid shifts in modern warfare driven by technologies such as artificial intelligence and unmanned systems.

The documents under review include the National Security Strategy, the National Defense Strategy, and the Defense Buildup Program. Key objectives involve integrating lessons from recent global conflicts, specifically regarding the tactical dominance of low-cost drones, autonomous systems, and AI-based command networks. The government also intends to expand long-range missile arsenals and ensure defense spending reaches 2% of GDP.

This strategic shift is prompted by a deteriorating regional security environment, including the military expansion of China—identified as Japan’s ‘greatest strategic challenge’—and increased military cooperation between China and Russia. Additionally, the government is looking to strengthen domestic defense industries and centralize intelligence capabilities to better respond to new forms of warfare.
