Japan’s Push for Independent AI Defense Capabilities Amid Shifting U.S. Policies

Japan's Strategic Push for AI in Defense

Japan faces a critical need to develop its own artificial intelligence technologies for defense amid shifting global alliances. With the United States adopting an “America First” stance under former President Donald Trump, reliance on U.S.-centric AI services may expose Japan to political vulnerabilities. Advanced AI is increasingly becoming a tool for geopolitical leverage, especially in defense and cybersecurity sectors.

AI as a Political and Defense Asset

David Ha, CEO of the Japanese AI startup Sakana AI, emphasizes the importance of Japan building its own AI capabilities. “AI services could serve as a bargaining chip for countries,” he said. The ability to produce and control AI systems is essential for maintaining national security and for Japan’s resilience in a changing geopolitical environment.

Japan’s alliance with the U.S. has become more uncertain due to calls for increased host-nation support and criticism of the alliance’s balance. This uncertainty highlights the need for Japan to reduce dependency and develop autonomous defense technology, including AI systems tailored to its specific needs.

AI Applications in Defense and Public Safety

Sakana AI is actively pursuing projects that intersect with government priorities, focusing on defense and public sector challenges. Their AI-driven simulations enable:

• Prediction of infectious disease outbreaks and their origins
• Detection of AI-generated images and videos related to war, propaganda, and natural disasters
• Accurate modeling of virus spread scenarios in the event of a bioattack, assisting in formulating countermeasures

These applications highlight how AI can enhance national preparedness and counter misinformation during crises.

Progress and Challenges for AI Integration in Defense

Despite Sakana AI’s rapid rise—becoming Japan’s fastest startup to reach unicorn status—the path to government adoption remains gradual. Defense-related collaborations typically require extended timelines due to the sensitive nature of the sector. Ha notes that engagement with public sector defense projects often spans years or even decades.

The startup recently earned recognition with an Innovative Spirit Award for its potential in dual-use security technology, reflecting growing interest in AI’s role in national defense. Currently, Sakana AI is in early talks with government entities, signaling a cautious but promising collaboration trajectory.

Government Commitment and International Context

Prime Minister Shigeru Ishiba has pledged to increase AI funding to over ¥50 trillion in the next decade, aiming to strengthen both government and corporate AI efforts. His meetings with U.S. tech leaders from companies such as OpenAI, AMD, and Nvidia underscore Japan’s intent to boost bilateral AI cooperation.

Globally, the U.S. and China dominate AI innovation, holding 60% of AI patents and producing a third of AI research. With most leading AI companies based in these two countries, Japan’s push to develop indigenous AI technology is a strategic move to secure its defense capabilities and reduce external dependencies.

Looking Ahead

Japan’s focus on AI in defense aligns with broader national security needs in an increasingly complex geopolitical landscape. Building domestic AI expertise and infrastructure will be key to maintaining sovereignty and operational readiness.
