India-Japan Relations

India-Japan relations represent a strong and future-oriented partnership built on civilisational links, democratic values, economic cooperation, technology collaboration, defence partnership and a shared commitment to a free, open and rules-based Indo-Pacific. The relationship has evolved into a Special Strategic and Global Partnership, with growing convergence in security, connectivity, supply chains, clean energy, digital technology and global governance.

Historical Background of India-Japan Relations

• Ancient to Cold War Phase- India-Japan relations began with Buddhist civilisational links in the 6th century and later gained political importance during India’s freedom struggle through leaders like Rash Bihari Bose and Subhas Chandra Bose. Diplomatic relations were established in 1952, but Cold War dynamics limited deeper strategic engagement.

• 2000–2006: Global to Strategic Partnership- Relations entered a new phase with the Global Partnership in 2000 and were upgraded to a Strategic and Global Partnership in 2006.

• 2008: Security Cooperation Framework- The Joint Declaration on Security Cooperation laid the foundation for structured defence ties.

• 2011: CEPA Signed- The Comprehensive Economic Partnership Agreement (CEPA) was signed to liberalise trade and strengthen economic engagement.

• 2014: Special Strategic and Global Partnership- Under the Modi-Abe leadership, India-Japan relations were upgraded to a Special Strategic and Global Partnership.

• 2015: India-Japan Vision 2025- Both countries announced India-Japan Vision 2025 to provide a long-term framework for cooperation in security, economy, technology and regional connectivity.

• 2016: Civil Nuclear Agreement- The India-Japan Civil Nuclear Agreement reflected high strategic trust, as Japan became willing to cooperate with India in the sensitive nuclear energy sector.

• 2017: Act East Forum- The Act East Forum was created to promote development cooperation in India’s Northeast and improve connectivity with Southeast Asia.

• 2019: 2+2 Ministerial Dialogue- The launch of the 2+2 Ministerial Dialogue strengthened high-level defence and foreign policy coordination.

• 2020: ACSA Agreement- The Acquisition and Cross-Servicing Agreement enabled logistics support between the armed forces of both countries.

• 2025: Joint Vision for the Next Decade- During Prime Minister Narendra Modi’s visit to Japan, both sides announced the India-Japan Joint Vision for the Next Decade, covering economic partnership, security, mobility, ecological sustainability, technology, innovation, health, people-to-people ties and state-prefecture engagement. Japan also pledged 10 trillion yen / USD 68 billion private investment over the next decade.

Areas of Cooperation Between India and Japan

Broad Area	Key Dimensions of Cooperation
1. Geopolitical & Strategic Cooperation	India and Japan share a common interest in a free, open, inclusive and rules-based Indo-Pacific. India’s Act East Policy and Indo-Pacific Oceans Initiative align with Japan’s Free and Open Indo-Pacific vision. Both countries cooperate through platforms such as the Quad, G20, G4, UN, CDRI, ISA and SCRI.
2. Defence & Security Cooperation	Defence cooperation has expanded through the Joint Declaration on Security Cooperation, 2+2 Ministerial Dialogue, ACSA, and regular military exercises such as Malabar, JIMEX, Dharma Guardian, Veer Guardian and Milan. Recent cooperation includes DRDO-ATLA collaboration on missile defence and maritime surveillance, along with movement towards co-production of defence equipment.
3. Indo-Pacific & Maritime Cooperation	Both countries support freedom of navigation, maritime security and a rules-based order in the Indo-Pacific. Their cooperation is significant in the context of China’s growing assertiveness in the Indo-Pacific, East China Sea and Indian Ocean Region.
4. Economic, Trade & Investment Cooperation	The CEPA 2011 liberalised trade between India and Japan. Bilateral trade reached about USD 25.15 billion in FY 2024–25, though the trade balance remains in Japan’s favour. Japan is also India’s 5th largest FDI source, with investment of around USD 43 billion in 2024.
5. Infrastructure & Connectivity Cooperation	Japan has been India’s largest Official Development Assistance donor since 1958. Major projects include the Mumbai-Ahmedabad High-Speed Rail, Delhi Metro support, industrial corridors and Northeast connectivity under the Act East Forum. Japan has also supported India’s broader vision for high-speed rail development.
6. Technology, Space & Innovation Cooperation	India and Japan are cooperating in AI, semiconductors, robotics, shipbuilding, space awareness, nuclear energy and digital technology. The Digital Partnership 2.0, India-Japan AI Initiative and ISRO-JAXA cooperation for the Chandrayaan-5 / LUPEX lunar polar mission reflect growing technological convergence.
7. Supply Chain & Economic Security Cooperation	Through the Supply Chain Resilience Initiative with Australia, India and Japan aim to diversify global supply chains and reduce over-dependence on a single country. The Joint Action Plan on Economic Security further strengthens cooperation in resilient manufacturing and critical sectors.
8. Energy, Climate & Green Cooperation	India and Japan cooperate on clean energy, hydrogen, ammonia, sustainable fuels and climate action. The Joint Crediting Mechanism under the Paris Agreement, declarations on Clean Hydrogen and Ammonia, and the Clean Energy Partnership 2022 are important initiatives in this area.
9. People-to-People & Skill Mobility	India’s young workforce and Japan’s ageing population create strong demographic complementarities. Both countries agreed on human resource exchange to facilitate mobility of 5 lakh people, including 50,000 Indian workers. However, people-to-people connectivity still remains below potential.
10. Africa & Regional Development Cooperation	India and Japan cooperate for development in Africa through the Asia-Africa Growth Corridor and the Japan-India Cooperation Initiative for Sustainable Economic Development in Africa. This reflects their shared interest in transparent, sustainable and rules-based development partnerships.

Challenges in India-Japan Relationship

Trade Imbalance- Despite CEPA, trade remains in Japan’s favour due to non-tariff barriers, strict import standards and slow CEPA reforms.
Divergent Strategic Outlooks- India’s strategic autonomy and Japan’s US alliance create differences on issues like Russia sanctions and the Ukraine war.
Different Regional Priorities- India prioritises South Asia and the Indian Ocean, while Japan focuses more on East Asia, China and North Korea.
Slow Project Implementation- Projects like the Mumbai-Ahmedabad High-Speed Rail and Asia-Africa Growth Corridor face delays.
Defence Procurement Issues- Deals like ShinMaywa US-2 remain stalled due to technology transfer and pricing concerns.
Limited People-to-People Ties- Small diaspora presence and limited student exchanges restrict deeper social and cultural connectivity.

Significance of India-Japan Relations

Indo-Pacific Stability- Cooperation through Quad and maritime frameworks supports a free, open and rules-based Indo-Pacific.
Strategic Balance in Asia- India’s Indian Ocean role and Japan’s East Asian position help balance China’s assertiveness.
Economic Development- Japanese investment supports India’s infrastructure, manufacturing, metro rail and high-speed rail projects.
Supply Chain Resilience- Cooperation reduces dependence on China-centric supply chains and promotes trusted networks.
Technology Partnership- Collaboration in AI, semiconductors, space, robotics and clean energy strengthens India’s technological capacity.
Global Governance Reform- Both cooperate in G20, G4 and UN reforms to reflect contemporary global realities.
Northeast Connectivity- Japan’s role under the Act East Forum strengthens India’s Northeast and Southeast Asia connectivity.

India and Japan should review CEPA, reduce trade imbalance, improve market access and remove non-tariff barriers. They should fast-track defence co-production, connectivity projects, Northeast development and cooperation in AI, semiconductors, 5G, space, clean energy and supply chains. Stronger student exchange, skill mobility, tourism and diaspora engagement can further make the partnership a key pillar of regional stability and a rules-based Indo-Pacific.
