India and Japan forge strategic AI alliance targeting ¥10 trillion investment over next decade

India-Japan Partnership Transforms Into Economic Security Alliance

The India-Japan partnership has undergone a decisive transformation, evolving from traditional development aid into a strategic AI alliance focused on economic security and technological sovereignty. At the 16th India-Japan Summit held during Japanese Prime Minister Sanae Takaichi's visit to India, both nations announced an ambitious roadmap that includes ¥10 trillion in Japanese investment over the next decade and plans to double the number of Japanese companies operating in India 5

. Foreign Secretary Vikram Misri described AI as a "major sunrise sector" in bilateral cooperation, with both countries aligning their vision on governance frameworks, innovation, infrastructure and applications. The collaboration brings together India's strengths in software engineering, digital public infrastructure, and AI talent with Japan's expertise in advanced manufacturing, robotics, semiconductors, and precision engineering 3

Strategic Focus on Semiconductors and AI Infrastructure

The strategic AI alliance recognizes that AI is not primarily a software story but equally a hardware story. Japan's dominance in the global silicon wafer supply through companies like Shin-Etsu and SUMCO complements India's opportunity in assembly, testing, system integration and the vast manufacturing ecosystem that a semiconductor industry requires . Both sides agreed to strengthen cooperation in secure digital ecosystems, including data centres, GPU capacity, semiconductors and AI compute resources, while assessing vulnerabilities across the AI technology stack from an economic-security perspective 4

. This talent exchange represents a strategic swap where India receives capital and manufacturing technology while Japan gains access to India's strong AI human capital. Key agreements include collaboration between IIT Bombay's BharatGen and Japan's National Institute of Informatics on multilingual scientific large language models, and between Sarvam AI and Preferred Networks on full-stack AI development 4

Defence Co-Development and Trusted Digital Innovation

Beyond AI, the 16th India-Japan Summit produced significant outcomes in defence cooperation. Modi announced that India and Japan have signed an agreement for their first defence co-development project involving the Naval Radio Antenna 'Unicorn', opening a new chapter in their defence technology partnership 2

Northeast India as Industrial Gateway to Indo-Pacific Strategy

The strategic importance of Northeast India has shifted from a connectivity project to an industrial gateway within the broader India-Japan partnership. The region is being linked to semiconductors, biofuels, industrial value chains, and skill development, with both countries committed to developing manufacturing corridors connecting the Northeast with the Bay of Bengal through BIMSTEC 1

. Three spotlight programmes reinforce this role: semiconductor activities, the newly launched Cooperative Biogas for Growth Initiative targeting 1,000 biogas plants, and emphasis on AI for infrastructure like roads, bridges, and power grids. The cooperation aligns with India's MAHASAGAR vision and Japan's updated Free and Open Indo-Pacific framework, including strengthening AI collaboration with like-minded countries across the Indo-Pacific and the Global South 4
