Japan’s Ministry of Defense has submitted a record defense budget request of approximately 8.9 trillion yen ($55.6 billion) for fiscal year 2027, marking a continued rise in the country’s military spending and signaling a significant shift in its national security strategy. The request reflects Tokyo’s efforts to enhance its Self-Defense Forces’ capabilities amid concerns over regional security challenges, particularly citing China’s growing military assertiveness.
Under a five-year defense plan established in 2022, Japan aims to increase defense spending to around 2 percent of its gross domestic product, effectively doubling previous commitments. The strategy focuses on expanding Japan’s military role beyond traditional homeland defense toward strengthening offensive and counterstrike capabilities. The Ministry of Defense plans to invest in advanced technologies including attack drones that can be deployed from the air or underwater, and hypersonic missiles launched from submarines. The budget request also includes funding to develop an integrated artificial intelligence (AI) platform for enhanced command and control functions, combining domestic and foreign technologies, including those from the United States.
Experts have noted this budget surge as part of a broader move by Japan to modernize and expand its military posture. Chen Hong, director of East China Normal University’s Asia Pacific Studies Center, described the increase as a systematic acceleration of Japan’s force transformation, shifting from defense-oriented operations to long-range strike and unmanned combat systems. Chen highlighted concerns about the regional implications, warning that Japan’s expanding military capabilities could elevate tensions and destabilize the security environment in Northeast Asia.
The Japanese government’s portrayal of China as a growing security threat has been a central justification for the defense buildup. Analysts such as Chen suggest that this narrative serves political aims to relax Japan’s longstanding constitutional restrictions on military expansion and security policy.
Similarly, Liu Shuliang, an associate researcher at the Tianjin Academy of Social Sciences, emphasized that Japan’s focus on emerging warfare technologies like AI and drones is designed to align with global military developments but also represents a departure from its traditionally defensive orientation. Liu indicated that Japan’s goal is to emerge as a major military power, a development that could trigger a regional arms race and increase risks of miscalculation or unintended escalation due to the widespread use of AI-enabled and unmanned weaponry.
Domestically, analysts point to challenges Japan faces, including an aging population, growing social security demands, and high public debt. Liu warned that prioritizing military expenditure over social needs might intensify internal tensions while complicating regional security dynamics.
Overall, Japan’s escalating defense budget and strategic shift have sparked concern among neighboring countries, who view the developments as signs of remilitarization that could further heighten geopolitical tensions and undermine peace and stability across the region.
