Major Pillars of the Partnership
Defence and Security Cooperation
India and Japan cooperate through:
- Annual Summit meetings
- Foreign and Defence Ministers’ 2+2 Dialogue
- Defence Ministerial Dialogue
- Defence Policy Dialogue
- Service-level staff talks
- Coast Guard cooperation
Major military exercises include:
- JIMEX/JAIMEX between the navies
- Dharma Guardian between the armies
- Veer Guardian between the air forces
- Malabar Exercise with the United States and Australia
The Acquisition and Cross-Servicing Agreement, signed in 2020 and effective from 2021, enables reciprocal logistical support between their armed forces. Cooperation is also expanding into maritime-domain awareness, defence technology, naval maintenance and joint production under Make in India.
Economic and Investment Partnership
Japan is an important source of:
- Foreign direct investment
- Technology
- Official Development Assistance
- Infrastructure finance
- Industrial expertise
The India–Japan Comprehensive Economic Partnership Agreement, in force since 2011, facilitates trade in goods, services and investment.
Key initiatives include:
- India–Japan Industrial Competitiveness Partnership
- Japan Industrial Townships
- Supply Chain Resilience Initiative
- SME and startup cooperation
- Investment in automobile, electronics, logistics and manufacturing sectors
At the 2026 Annual Summit, both sides agreed to review the CEPA and improve the investment environment. They also noted progress towards the investment and financing target of 10 trillion yen announced in 2025.
Infrastructure and Connectivity
Japan has played an important role in financing and developing major infrastructure projects in India, including:
- Delhi Metro
- Mumbai–Ahmedabad High-Speed Rail
- Dedicated Freight Corridors
- Metro systems
- Industrial corridors
- Urban transport and water projects
India has been one of the largest recipients of Japanese Official Development Assistance. The two countries also cooperate on connectivity between South Asia and Southeast Asia through the synergy between India’s Act East Policy and Japan’s Partnership for Quality Infrastructure.
Economic Security and Critical Technologies
Economic security has emerged as a major pillar of the partnership. Cooperation focuses on:
- Semiconductors
- Critical minerals
- Information and communication technology
- Pharmaceuticals
- Clean energy
- Resilient supply chains
The two countries oppose economic coercion, arbitrary export restrictions and excessive dependence on a single country for strategic goods. In 2026, they adopted a Joint Declaration on Economic Security Cooperation to promote project-based collaboration in critical sectors.
Energy and Climate Cooperation
India and Japan cooperate through the Clean Energy Partnership in areas such as:
- Green hydrogen
- Clean ammonia
- Solar energy
- Biofuels and biogas
- LNG
- Nuclear energy
- Energy efficiency
- Strategic petroleum reserves
In 2026, the two countries launched the Cooperative Biogas for Growth Initiative and agreed to deepen cooperation on energy resilience and secure maritime energy supply chains.
Science, Technology and Digital Cooperation
Cooperation is expanding in:
- Artificial intelligence
- Digital public infrastructure
- 5G and telecommunications
- Quantum technology
- Space
- Cybersecurity
- Robotics
- Biotechnology
The inaugural India–Japan AI Strategic Dialogue was held in 2026, and the two sides adopted a joint statement promoting safe, secure, trusted and human-centric artificial intelligence.
People-to-People Relations
Both countries promote cooperation in:
- Education and research
- Tourism
- Skill development
- Japanese-language training
- Student and professional exchanges
- Healthcare and nursing
- Cultural exchanges
Japan’s ageing population and labour shortages create opportunities for skilled Indian professionals, while closer educational and cultural interaction can provide a stronger social foundation for strategic ties.
Indo-Pacific Significance
India and Japan share an interest in:
- Freedom of navigation
- Respect for international law
- Peaceful resolution of disputes
- Maritime security
- Secure sea lanes
- Opposition to unilateral changes in the status quo
Japan’s Free and Open Indo-Pacific vision aligns closely with India’s Indo-Pacific Oceans Initiative and MAHASAGAR framework. Both are also members of the Quad, along with Australia and the United States.
Significance for India
- Provides access to capital and advanced technology.
- Supports infrastructure development and industrialisation.
- Strengthens India’s maritime and defence capabilities.
- Helps diversify supply chains away from excessive dependence on China.
- Supports Make in India and Atmanirbhar Bharat.
- Strengthens India’s Act East Policy and Indo-Pacific role.
- Provides cooperation in semiconductors, critical minerals and clean energy.
Challenges
- Bilateral trade remains below its potential.
- India continues to face a considerable trade deficit with Japan.
- Japanese investment is concentrated in a few sectors and regions.
- Regulatory and land-acquisition difficulties affect projects.
- The high-speed rail project has faced delays and cost concerns.

- Language and cultural barriers limit people-to-people exchanges.
- Both countries sometimes differ in their economic and diplomatic approaches towards China and Russia.
Way Forward
- Accelerate CEPA review and diversify bilateral trade.
- Promote joint defence research, co-development and manufacturing.
- Expand semiconductor and critical-mineral partnerships.
- Improve the ease of doing business for Japanese companies.
- Complete major infrastructure projects within revised timelines.
- Strengthen cooperation in India’s Northeast and the wider Indo-Pacific.
- Expand student, professional and skilled-worker mobility.
- Convert strategic convergence into commercially viable projects.
Conclusion
The India–Japan Special Strategic and Global Partnership has evolved from an economic relationship into a broad strategic partnership based on shared democratic values, mutual trust and common Indo-Pacific interests.
Its future significance lies in combining India’s scale, human resources and growing market with Japan’s capital, technology and industrial capabilities. Effective implementation of defence, economic-security, connectivity and technology initiatives can make the partnership an important pillar of a stable and prosperous Indo-Pacific.
