Challenges to India and Japan Relations

• The China Factor in Indo-Pacific Stability: Chinese maritime assertiveness in the East and South China Seas threatens regional security.
  • India is more vocal in criticising Beijing, while Japan remains cautious due to economic interdependence.
  • Overdependence on China for semiconductors and critical minerals exposes vulnerabilities.
  • Efforts for supply chain diversification need greater investment and technology transfer.
  • India’s post-Galwan clash (2020) balancing act—deepening ties with Japan while cautiously engaging China—shows the trust deficit persists.
• Geopolitical Balancing and Strategic Autonomy: The regional balance of power is shaped by the interplay of the US, China, Japan, and India.
  • Trump 2.0’s tariff policies and unpredictability weaken Quad coherence and complicate long-term strategy.
  • India maintains strategic autonomy, balancing Quad cooperation with membership in BRICS, SCO, and AIIB, while Japan follows a more pro-US orientation.
  • Russia factor: Japan adheres to US–G7 sanctions, while India continues energy imports and defence cooperation with Moscow. India’s participation in Vostok Exercises near the disputed Kuril Islands highlighted divergences.
• Economic and Demographic Challenges: Bilateral trade remains modest compared to India–China trade volumes.
  • Indian exporters face language barriers, quality standards, and policy divergences on E-commerce rules (Osaka Track) and RCEP membership.
  • Japan’s ageing population and India’s youthful workforce create natural complementarities, but lack of migration frameworks, skill partnerships, and social security coordination limit potential gains.
• Strategic and Infrastructure Collaboration Issues: The Asia–Africa Growth Corridor (AAGC) struggles with financing, feasibility, and scale, weakening its image as a counterweight to China’s BRI.
  • Defence cooperation faces bureaucratic delays, cost challenges, and stalled negotiations (e.g., US-2 amphibious aircraft deal).
  • India’s push for defence exports may sometimes compete with Japanese ambitions, creating friction in collaboration.

Way Forward

• Enhancing Regional Role: India and Japan should leverage their economic and military strengths to offer a credible counterbalance to China in the Indo-Pacific.
  • Strengthening Quad-based initiatives, joint naval exercises, and cyber-security cooperation can reinforce deterrence.
• Green Technologies and Environmental Cooperation: Japanese innovations can help India combat pollution and climate change.
  • Examples include the Miyawaki afforestation technique and the Joint Crediting Mechanism (JCM) that incentivises low-carbon technology transfer.
• Addressing Trade Bottlenecks: Expanding trade beyond automobiles and IT into pharmaceuticals, digital services, and green tech is crucial.
  • Joint ventures merging Japanese manufacturing expertise with Indian raw materials and labour can strengthen supply chains.
• Defense and Strategic Cooperation: Finalising the US-2 aircraft deal and deepening cooperation in submarines, robotics, quantum technology, and unmanned vehicles will expand strategic trust.
• People-to-People and Workforce Exchanges: Encouraging migration of Indian IT professionals and skilled workers can support Japan’s digitalisation and ageing society.
  • Academic and cultural exchange will cement long-term societal linkages.
• Expanding Science & Technology Partnerships: Cooperation in 5G, submarine cable systems, quantum communication, and semiconductor R&D will help both nations reduce technological dependence on China.
• Strategic Connectivity and Infrastructure: Linking South Asia with Southeast Asia through synergy of India’s Act East Policy and Japan’s Partnership for Quality Infrastructure will boost regional influence.
  • Joint projects in Africa and Southeast Asia can enhance credibility of development partnerships.

Conclusion

• The India–Japan partnership has evolved from aid-driven cooperation to a comprehensive strategic alliance with global implications. The 15th Annual Summit marks a leap forward, embedding cooperation in economic security, critical technologies, climate, and space exploration, while reinforcing traditional defence and infrastructure pillars.
