Expanding Horizons: Japan’s Infrastructure Investments in India

Japan is significantly enhancing its infrastructure partnership with India, extending beyond the high-profile Mumbai–Ahmedabad bullet train project. During a recent summit, Prime Minister Narendra Modi and Japanese Prime Minister Shigeru Ishiba unveiled a “Joint Vision for the Next Decade,” aiming to mobilize $67 billion in private investment across various sectors, including clean energy, semiconductors and defense cooperation.

The Japan International Cooperation Agency (JICA) has been instrumental in financing major metro rail systems in India. In March 2025, JICA signed a loan agreement of ₹4,649 crore for Delhi Metro Phase 4, addressing congestion and pollution issues. Over the past two decades, JICA has extended loans exceeding ¥1.3 trillion to metro systems in cities such as Delhi, Bengaluru, Chennai, Mumbai, Kolkata and Ahmedabad.

Japan’s involvement extends to critical infrastructure projects like the Mumbai Trans Harbour Link, India’s longest sea bridge, which opened in January 2024. JICA financed approximately 85% of the project’s total cost through Official Development Assistance (ODA) loans. Additionally, Japan is supporting the Western Dedicated Freight Corridor, linking Delhi and Mumbai, with a loan of about ₹2,254 crore, facilitating efficient freight movement.

This comprehensive collaboration underscores Japan’s commitment to India’s infrastructure development, fostering economic growth and regional connectivity.
