Japan's defense market growth is largely fueled by a steady increase in the nation's budget to strengthen military capabilities. With the growing security concerns in the Asia-Pacific, particularly due to the rise of China and North Korea’s provocative actions, the country is prioritizing the modernization of its defense infrastructure. In December 2024, the cabinet of the Japanese Prime Minister approved about ¥ 8.7 Trillion in defense spending for the fiscal year 2025. This is enabling the acquisition of advanced technologies and improved defense systems, from missile defense to unmanned systems.

Additionally, the growth of the country is also driven by a strong focus on modernizing its self-defense forces (SDF) in response to changing local and regional threats. This effort includes upgrading military assets like replacing outdated fighter jets with advanced F-35s, improving naval capabilities, and expanding missile defense systems. Furthermore, Japan is making significant strides in new areas such as space defense and unmanned technologies, thereby understanding their critical role in future security challenges. In October 2024, the defense ministers of Japan, Italy, and the UK agreed to develop a next-generation fighter jet to replace Japan's retiring F-2s. Besides this, the integration of advanced technologies, such as unmanned systems, artificial intelligence, and robotics, is crucial in replacing the workforce and maintaining operational efficiency. Drones, autonomous vehicles, and AI-driven systems are becoming more prominent, which is ensuring Japan's military remains strong and capable.
