India and Japan on Thursday moved to strengthen defence cooperation with a new maritime security agreement covering information sharing, maritime domain awareness, search and rescue, and humanitarian assistance. Defence Minister Rajnath Singh and Japanese Defence Minister Shinjiro Koizumi held bilateral talks in New Delhi as the two countries sought to deepen strategic coordination in the Indo-Pacific.

The agreement marks another step in the expanding India-Japan defence partnership. Both sides also discussed defence equipment and technology cooperation, military exchanges, industrial collaboration and efforts to strengthen the resilience of supply chains.

The talks come against a changing security environment across the Indo-Pacific, where India and Japan have increasingly aligned their interests around maritime security and a free, open and rules-based regional order.

New Maritime Security Pact

The two defence ministers signed a Memorandum of Arrangement on Maritime Security Cooperation. The pact will provide a framework for greater cooperation between the Indian Navy and the Japan Maritime Self-Defense Force.

The agreement covers maritime domain awareness, information exchange, search-and-rescue activities and humanitarian assistance and disaster relief. These areas can improve coordination during maritime emergencies and natural disasters while strengthening operational communication between the two forces.

The arrangement also provides scope for the two navies to build practical cooperation through existing defence exchanges and maritime activities.

Focus On Indo-Pacific

Singh and Koizumi reiterated the importance of maintaining a free, open, peaceful and resilient Indo-Pacific.

India and Japan have expanded their strategic partnership in recent years through regular defence ministerial meetings, military exercises and high-level diplomatic engagement. Maritime cooperation has become a central component of that relationship because both countries depend heavily on secure sea lanes for trade and energy supplies.

The latest agreement gives greater institutional support to that cooperation.

Push For Defence Manufacturing

Defence manufacturing and technology remained another major focus of the discussions.

India has been seeking greater foreign investment, technology partnerships and domestic production under its Make in India and defence indigenisation initiatives. Japan, meanwhile, has been expanding defence equipment and technology cooperation with partners amid a more challenging regional security environment.

The two sides discussed opportunities to strengthen industrial cooperation and encourage collaboration between their defence sectors. The joint statement also highlighted the importance of cooperation in defence equipment and technology.

Military Interoperability Expands

India and Japan have steadily increased military-to-military engagement. Their cooperation includes exercises, training exchanges and discussions between the armed forces.

The maritime agreement could further improve coordination between the Indian Navy and Japanese maritime forces, particularly in areas requiring timely information exchange and joint responses.

Both countries have also previously explored cooperation involving ship maintenance in India and other defence-industrial initiatives. Japan's defence ministry has described equipment and technology cooperation with India as an important part of the bilateral security relationship.

Japan Disaster Response Highlighted

During the meeting, Singh expressed India's solidarity with Japan following the recent earthquake in the country.

He praised Japan's emergency response and preparedness and reaffirmed India's willingness to provide assistance and support during the recovery effort. The reference to disaster response also underlined the practical importance of humanitarian assistance and disaster relief cooperation in the new maritime arrangement.

For both countries, disaster-response capabilities are increasingly viewed as part of broader maritime security cooperation.

Regional Security In Focus

The discussions took place as India and Japan face a more complex security environment across the Indo-Pacific.

Japan continues to monitor developments involving North Korea and regional maritime security, while India remains focused on the security of the Indian Ocean and wider Indo-Pacific. Tokyo has also been strengthening defence partnerships with several regional countries.

Japan's Defence Ministry has separately highlighted the increasingly challenging regional security environment and the need for stronger cooperation with partners.

What The Pact Means

The latest agreement adds a practical maritime component to the broader India-Japan strategic partnership. It can help both countries improve information exchange, coordinate humanitarian responses and build greater familiarity between their naval forces.

For India, stronger Japanese defence cooperation can support its maritime-security priorities and defence manufacturing ambitions. For Japan, deeper engagement with India strengthens its network of security partnerships across the Indo-Pacific.

The India-Japan defence pact therefore goes beyond a single agreement, reinforcing a wider partnership focused on maritime security, technology, industrial cooperation and a stable Indo-Pacific.
