India and Japan Sign Maritime Security Pact to Deepen Defence Ties
India and Japan have entered into a Memorandum of Arrangement on Maritime Security Cooperation to strengthen operational ties, information exchange, and defence industry collaboration. The agreement was reached during high-level ministerial discussions held in New Delhi between Indian Defence Minister Rajnath Singh and Japanese Defence Minister Shinjiro Koizumi.
What Happened
During their bilateral meeting on August 20, 2026, the defence ministers agreed to enhance defence cooperation under the framework of the Japan-India Special Strategic and Global Partnership. Both nations reaffirmed their commitment to maintaining a free and open Indo-Pacific amid escalating global tensions, voicing opposition to unilateral attempts to alter the status quo through coercion or force, as well as actions hindering freedom of navigation and overflight.
The newly formalised maritime arrangement establishes a cooperative framework uniting the Indian Navy and the Japan Maritime Self-Defense Force. This initiative covers Maritime Domain Awareness, humanitarian assistance, disaster relief, and search and rescue operations.
Key Highlights
- Maritime Security Framework: Enhanced operational coordination, reciprocal access to ports, logistics support, and maintenance and ship repair facilities between both navies.
- Protection of Sea Lanes: Stronger measures to safeguard Sea Lines of Communications through regular naval visits, personnel exchanges, and subject matter expert discussions.
- Naval Co-development and Shipbuilding: Joint exploration of naval shipbuilding and design by combining Japanese technological capability with Indian manufacturing facilities under the Make in India initiative, alongside cooperation in mine countermeasures.
- Expanded Military Drills: Broadening of bilateral drills including Dharma Guardian, JAIMEX, and the Veer Guardian 26 air exercise, which will feature Japanese fighter aircraft operating in India for the first time.
- Integration of Modern Capabilities: Plans to integrate unmanned systems into exercises, explore short-notice joint drills, and facilitate interactions between Special Operations Forces, with future cooperation planned for India’s integrated theatre commands.
- Defence Equipment and Technology: Recommitment to the early realisation of the shipborne UNICORN integrated communications antenna system, collaboration between India’s DRDO and Japan’s ATLA, and the establishment of a Defence Industry Forum.
- Joint Working Group: Creation of a dedicated Working Group led at the Director-General or Joint Secretary level to manage cooperation spanning intelligence, technology, equipment, and operations.
Why This Matters
The agreement provides an institutional structure for the two countries to protect essential maritime corridors and coordinate responses during regional contingencies. By linking Japan’s technological expertise with India’s domestic production base, both nations aim to expand naval construction, repair infrastructure, and defence technology sharing, while maintaining regional stability across sea and air routes.
What to Watch Next
Looking ahead, the two nations agreed to accelerate preparations for the fourth India-Japan 2+2 Foreign and Defence Ministerial Dialogue scheduled to take place in Tokyo later this year. Additionally, observers will monitor the implementation of the UNICORN antenna system project and the inaugural deployment of Japanese fighter jets to India for the Veer Guardian 26 exercise.
