Japan Restructures Its Defense Posture In A More Contested Asia-Pacific

Japan is undergoing its most significant transformation in defense policy since World War II. Under Prime Minister Sanae Takaichi, reforms initiated under her predecessors are increasingly being translated into greater military capabilities and a more proactive security strategy. The shift reflects a changing Asia-Pacific security environment, growing US pressure on allies to share the defense burden and the growing convergence of economic and national security. For businesses, the transformation presents significant opportunities across Japan’s defense industrial base. But careful balancing will be needed against rising geopolitical risk, regulatory complexity and supply chain realignment to successfully leverage Japan’s burgeoning industry.
