As maritime connectivity becomes central to economic security and regional stability, India and Japan are expanding cooperation across ports, logistics, supply chains, and Indo-Pacific connectivity. The partnership between RIS-CMEC, JTTRI, and the Indian Ports Association reflects a growing commitment to building resilient maritime infrastructure and a rules-based regional order.
Maritime connectivity is no longer a technical subject limited to ports, ships, and cargo movement. In the 21st century, it has become a central pillar of international relations. The security of sea lanes, the efficiency of port infrastructure, the resilience of supply chains, and the sustainability of ocean-based development now directly shape national growth and regional stability.
This is especially true in the Indo-Pacific. The region sits at the heart of global trade, energy flows, and strategic competition. More than 80 percent of global trade by volume moves by sea, and recent disruptions in the Red Sea, the Strait of Hormuz, and the South China Sea have shown how quickly maritime instability can affect fuel prices, food security, shipping costs, and industrial supply chains. Maritime trade is also entering a more uncertain phase. UNCTAD has noted that global seaborne trade grew by 2.2 percent in 2024 but was expected to slow sharply in 2025, reflecting geopolitical disruption, rerouting, and pressure on global logistics.
For India and Japan, this changing maritime environment is not distant. It is central to their strategic and economic future. Both countries are major Indo-Pacific stakeholders, both depend on secure sea lanes, and both have an interest in preserving a free, open, inclusive, and rules-based maritime order. Their cooperation has therefore moved beyond naval diplomacy. It now includes port modernisation, maritime domain awareness, supply chain resilience, blue economy partnerships, digital port systems, green shipping, and regional connectivity.
India's Maritime Transformation and Vision 2047
India’s maritime ambitions have gathered considerable momentum. Under the Sagarmala programme, India is implementing 845 projects worth around ₹6.06 lakh crore, with 315 projects worth about ₹1.57 lakh crore already completed. India’s major ports handled a record 915 million tonnes of cargo in FY 2025–26, reflecting the growing scale of the country’s maritime economy. Sagarmala 2.0, backed by a proposed support of ₹85,482 crore, is expected to catalyse further investment in port-led development, coastal shipping, shipbuilding, and logistics infrastructure.
The direction is clear: India wants to become a global maritime leader by 2047. The Maritime Amrit Kaal Vision 2047 sets this ambition within a wider framework of port capacity expansion, logistics efficiency, shipbuilding, cruise tourism, inland waterways, and green maritime development. Recent policy steps also show a shift toward performance-based and technology-driven port governance. In May 2026, India launched the Logistics Port Performance Index for FY 2024–25, along with new digital initiatives aimed at improving transparency, governance, and ease of doing business in the shipping ecosystem. This is important because future maritime competitiveness will depend not only on building more infrastructure, but on making ports smarter, faster, cleaner, and globally benchmarked.
Japan's Role in Shaping Indo-Pacific Connectivity
Japan brings a complementary strength to this partnership. Its Free and Open Indo-Pacific vision is built around the rule of law, connectivity, quality infrastructure, and the safe use of the maritime commons. Japan has long experience in port management, shipping technology, logistics systems, resilient infrastructure, and maritime safety. For Japan, India’s ports and maritime corridors are increasingly relevant not only as economic opportunities but also as strategic nodes in a wider Indo-Pacific connectivity network.
From Strategic Convergence to Practical Cooperation
Recent developments show that this convergence is becoming more operational. In April and May 2026, Japanese delegations engaged with Deendayal Port Authority at Kandla to explore cooperation in shipbuilding, ship repair, port development, and maritime infrastructure. This is significant because Kandla is not merely a port; it is a strategic gateway for northern and western India and a potential node in future supply chain and energy corridors. Such port-level engagement indicates that India-Japan maritime cooperation is moving from broad strategic language to practical project identification.
The Quad and the Emerging Maritime Architecture of the Indo-Pacific
At the multilateral level too, the maritime agenda is becoming more concrete. The Quad Foreign Ministers’ Meeting in New Delhi in May 2026 announced new initiatives on maritime security, port infrastructure, energy security, and supply chains. The Quad also welcomed India’s operationalisation of the Indian Ocean Region programme under the Indo-Pacific Partnership for Maritime Domain Awareness through the Information Fusion Centre–Indian Ocean Region in Gurugram. This matters because maritime domain awareness is no longer only a defence issue. It is essential for tracking illegal fishing, securing shipping routes, responding to disasters, monitoring grey-zone activity, and protecting trade.
Why the RIS–JTTRI–IPA Partnership Matters
In this wider context, the signing of a Memorandum of Understanding between the Centre for Maritime Economy and Connectivity at RIS, the Japan Transport and Tourism Research Institute, and the Indian Ports Association is a timely and meaningful step. The MoU creates an institutional foundation for sustained academic exchange, joint research, policy dialogue, and practical cooperation in the maritime and port sectors. It brings together research capacity, Japanese transport expertise, and India’s port-sector institutional network.
The value of such a partnership lies in its ability to connect strategy with implementation. Maritime cooperation cannot be built only through diplomatic statements. It requires data, technical studies, port-level assessments, industry participation, training, and regular policy engagement. Research institutions and port authorities can help identify where cooperation is most feasible: digital port systems, logistics benchmarking, ship repair, green hydrogen export infrastructure, coastal shipping, maritime skill development, blue economy financing, and sustainable port operations.
Ports, Supply Chains, and the Future of India–Japan Economic Relations
There is also a strong economic case. India-Japan bilateral trade stood at around US$27.47 billion in FY 2025–26, but the relationship still has considerable untapped potential. The 7th India-Japan CEPA Joint Committee Meeting held in Tokyo in March 2026 reviewed the implementation of the trade agreement and discussed ways to strengthen bilateral economic engagement. Better maritime connectivity can support this goal by reducing logistics friction, improving supply chain reliability, and enabling more efficient movement of goods between Indian and Japanese firms.
Building a Sustainable and Rules-Based Maritime Order
The strategic case is equally important. The Indo-Pacific is witnessing growing competition over ports, sea lanes, undersea infrastructure, energy routes, and island connectivity. Many developing countries in the region need better maritime infrastructure, but they also seek partnerships that are transparent, sustainable, and respectful of sovereignty. India and Japan are well placed to offer such a model. Their cooperation can support an alternative approach to connectivity: one based on quality infrastructure, local capacity-building, environmental sustainability, and open regional norms.
The roundtable on India-Japan Maritime Cooperation and Imperatives for the Indo-Pacific should therefore focus on concrete questions. How can Japanese expertise support India’s port modernisation and ship repair ecosystem? How can Indian ports become stronger nodes in Indo-Pacific supply chains? What role can digital port systems and performance benchmarking play in improving competitiveness? How can both countries cooperate on maritime sustainability and green shipping? And how can institutional partnerships generate regular, evidence-based recommendations for policymakers?
The Next Phase of India–Japan Maritime Cooperation
For India and Japan, the maritime domain is not simply a space of transit. It is a space of opportunity, responsibility, and shared leadership. India offers geography, scale, and a rapidly expanding maritime economy. Japan offers technology, capital, institutional experience, and a long-standing commitment to a rules-based maritime order. Together, they can help shape a more secure, connected, and sustainable Indo-Pacific.
The CMEC-RIS, JTTRI, and IPA partnership is therefore more than a ceremonial MoU. It reflects the next stage of India-Japan cooperation: practical, institutional, and outcome-oriented. As maritime challenges become more complex, the success of the India-Japan partnership will depend on its ability to convert strategic convergence into port-level, policy-level, and region-level outcomes.
If pursued with seriousness, India-Japan maritime cooperation can become one of the defining pillars of their Special Strategic and Global Partnership and a meaningful contribution to the future stability of the Indo-Pacific.
