Japan national security and defense strategy evolution

Overview

Japan is implementing a comprehensive shift in its national security posture, transitioning from reactive defense to a proactive strategy focused on great power competition. Under the “Japan National Defense 2026” document and the Defense White Paper released under Prime Minister Sanae Takaichi, the government is integrating diplomacy, defense, economy, technology, and intelligence into a unified national power strategy.

Key components include the acceleration of long-range missile defense architecture and the establishment of the National Intelligence Office. This new agency, comprising approximately 700 personnel, aims to centralize strategic information, surveillance, and cyber capabilities. To bolster these efforts, the Ministry of Defense plans to deploy advanced artificial intelligence for preemptive cyber defense. National Cyber Director Yoichi Iida noted that as AI models become more proficient at detecting vulnerabilities, the speed of attacks may increase, making sophisticated AI defense “inevitable.”

Under Prime Minister Takaichi, the government is accelerating revisions to its three core security documents—the National Security Strategy, the National Defense Strategy, and the Defense Buildup Program—with a target completion date by the end of 2026. Takaichi has identified AI and unmanned systems as central pillars of this strategy, noting they evolve faster than traditional equipment. The Ministry of Defense has requested a record budget of 8.89 trillion yen for the 2027 fiscal year to support developments like low-cost attack drones and AI-integrated command structures.

These developments are driven by regional tensions, identifying China as the “principal strategic challenge” and acknowledging the possibility of conflict regarding Taiwan. Other drivers include North Korea’s nuclear programs and increased military coordination between China, Russia, and North Korea.
