Opinion: Japan has entered a new strategic era, coupling its revitalised Free and Open Indo-Pacific vision with an expanded Official Security Assistance program to transform from a passive donor into an active regional security provider, linking defence, diplomacy, and industry to reshape the Indo-Pacific’s strategic landscape, explains PACFORCE’s Guy Boekenstein.
This week Japan unveiled two landmark foreign policy initiatives that signalled a historic evolution in its regional role: a renewed commitment to the Free and Open Indo-Pacific (FOIP) vision and the rapid expansion of its Official Security Assistance (OSA) program.
Together, these initiatives represent a transformation in Japan’s defence diplomacy linking economic development, dual-use innovation, and regional security in ways that could redefine the Indo-Pacific’s strategic landscape.
From vision to implementation: The Free and Open Indo-Pacific
Originally introduced by former Prime Minister Shinzo Abe in 2016, FOIP has become the strategic centrepiece of Japan’s foreign and security policy. Prime Minister Sanae Takaichi’s reaffirmation of FOIP this week underscores its centrality to Japan’s efforts to maintain peace, connectivity and rules-based order across the Pacific and Indian Oceans.
The framework integrates economic, diplomatic and defence instruments to foster regional stability and counter coercive influence, particularly in the maritime domain.
FOIP’s strength lies in its recognition that economic and national security are increasingly intertwined. The framework connects Asian and African economies through infrastructure, digital technology and defence capacity-building, transitioning Japan from a primarily financial donor to an active strategic partner.
In doing so, FOIP supports broader multilateral and minilateral frameworks, including ASEAN, the Quad, and AUKUS, as part of a networked approach to regional stability.
Official Security Assistance: Japan’s strategic pivot
To operationalise FOIP, Japan’s National Security Strategy established OSA as a core mechanism for delivering tangible defence and dual-use capabilities to partner nations. OSA serves as a direct counterweight to China’s Belt and Road Initiative by offering recipient states practical security cooperation based on transparency, rule of law and sovereignty.
Through OSA, Japan provides equipment, training and technology for non-combat operations such as maritime surveillance, disaster response and peacekeeping. The program currently supports 16 countries and multinational organisations across six key domains:
- Disaster risk reduction
- Maritime security and safety
- Mine clearing
- Counter-terrorism
- Counter-piracy
- Post-conflict management
OSA marks a historic policy shift away from Japan’s postwar restrictions on arms exports. For decades, Tokyo’s interpretation of Article 9 of its constitution prohibited the transfer of defence technology abroad.
The OSA program changes this, enabling Japan to engage directly in defence capacity-building without contravening its pacifist principles.
Financially, OSA has expanded rapidly: its budget has quadrupled over three years, reaching US$56 million in FY2024–25, with projections of up to $136 million by FY26–27. The program rests on three foundational pillars:
- Peace, stability, and rule of law – reinforcing maritime governance and freedom of navigation.
- Humanitarian assistance – supporting disaster relief, medical evacuation and post-crisis recovery.
- International peace cooperation – improving interoperability with partner militaries and regional organisations.
Implications for the Australian defence sector
Japan’s re-emergence as an active security provider opens significant opportunities for defence and technology industries across the Indo-Pacific, including, of course, Australia, now with the SEA 3000 decision.
Japanese defence primes including Kawasaki Heavy Industries, Mitsubishi Heavy Industries, Mitsubishi Electric, NEC Corporation, and Japan Marine United Corporation are now integrating OSA-related objectives into their research and development and export strategies. These firms are focusing on capabilities that enhance situational awareness, maritime patrol and interoperability with allied forces.
By aligning industrial policy with defence diplomacy, Japan is positioning itself not merely as a donor but as a regional integrator – organising, training and equipping partner militaries while cultivating enduring industrial relationships.
This strategy strengthens the Indo-Pacific’s defence ecosystem and supports the development of interoperable, scalable technologies across multiple domains. It also offers new opportunities for the Australian defence industry sector.
Strategic outlook
Japan’s OSA and FOIP frameworks mark a decisive end to its postwar limitations on defence engagement. By coupling diplomatic outreach with industrial collaboration, Tokyo is constructing a more resilient regional order rooted in deterrence, transparency and shared prosperity.
For allied nations and defence companies, Japan’s evolving role offers both opportunity and a model: a pragmatic balance of hard power and economic statecraft. As Prime Minister Takaichi’s administration continues to deepen engagement across allied nations, Japan’s integrated approach – anchored in dual-use innovation and interoperability – may well define the Indo-Pacific’s next era of strategic cooperation.
