Budget Request Structure

The 8.9 trillion yen figure is an opening bid rather than a final price tag. The request will be sent to the Finance Ministry for consideration before a decision in late December. Prime Minister Takaichi Sanae's government plans to revise the National Security Strategy, National Defense Strategy, and Defense Buildup Program by the end of 2026. Procurement quantities for some major equipment could change as part of that review.

Defense Transformation Priorities

The ministry organized the request around three main pillars and nine priority areas. The first pillar covers AI, unmanned systems, stand-off capabilities, integrated air and missile defense, space, and cyber. The second focuses on sustained response capabilities, including Pacific and sea-lane defense. The third centers on the foundations of defense, including the defense industrial and technological base and personnel.

AI and Unmanned Systems

The ministry plans an AI-based decision-support system for the Self-Defense Forces' Joint Operations Command. The request includes a next-generation AI platform and secure cloud infrastructure. It also includes UAVs for intelligence, surveillance, reconnaissance, and targeting, attack UAVs, small unmanned ground vehicles, and research into a stand-off missile launch module for unmanned underwater vehicles. The Acquisition, Technology, and Logistics Agency requested 234 billion yen ($1.5 billion) for the Global Combat Air Program fighter jet, plus an item request.
