The Quiet Partner at the Top: Japan’s Rise to India’s Largest FDI Source

Last week, the Department for Promotion of Industry and Internal Trade (DPIIT) released data on finance and capital for the first quarter of Financial Year 2026-27. One line deserved more attention than it received in the daily news cycle: Japan became India’s largest single source of Foreign Direct Investment. Japan contributed $5.71 billion of the aggregate $19.81 billion that came in between April and June. Public cooperation also advanced through Japanese yen loans worth JPY 275.858 billion for urban transport, healthcare and agriculture projects. Bilateral efforts focused on manufacturing, automobiles, semiconductors, clean energy, critical minerals, digital technology and supply-chain resilience. Both countries also promoted local-currency transactions, payment-system cooperation and the longer-term goal of mobilising JPY 10 trillion in private investment. For those who have tracked and analysed the financial and supply-chain relationship between India and Japan, the number was less of a surprise and more of a confirmation; the data has finally synchronised with a positive shift that has been building for a while.

From Maruti to the Metro: A Four Decade Arc

It is worth recalling how this meaningful relationship began. In 1982, Suzuki Motor Corporation of Japan signed a joint venture agreement with the Government of India to set up Maruti Udyog Limited, taking an initial 26 per cent stake in a company that was majority-owned by the Indian government. By any measure, this was an act of faith on both sides; India was still operating under an import-substitution regime, and Suzuki was the first Japanese manufacturer to bet on the opening of India’s economy. The Maruti 800 was launched in 1983 at Rs. 47,500. Within two and a half decades, Suzuki went from being a minority partner to becoming the full owner, having bought out the government’s residual stake by 2007. That single project arguably did more to shape India’s auto-component ecosystem through ancillary units, supplier discipline and shop-floor quality culture than any policy initiative of that era.

For the two decades that followed, the Japan relationship was defined less by equity and more by concessional development finance. The Japan International Cooperation Agency (JICA) became, in effect, India’s largest external partner for urban infrastructure. It financed and provided technology for the Delhi Metro from its earliest phases, funded close to 90 per cent of the cost of the Western Dedicated Freight Corridor and underwrote a substantial share of the Mumbai Trans Harbour Link. This was patient, low-visibility capital, structured as Official Development Assistance rather than equity. It rarely showed up at the top of country-wise FDI tables dominated by Singapore’s treaty-routed flows or Mauritius’s historical tax advantages. Japan was, in a sense, undertaking the plumbing while other jurisdictions took the visible investment credit.

The equity side of that story is easy to miss because, for years, there was so little of it. DPIIT’s calendar-year series shows Japanese FDI equity of under half a billion dollars in almost every year between 2000 and 2006, as low as $94 million in 2003, before Daiichi Sankyo’s acquisition of Ranbaxy took the 2008 figure to $4.47 billion, the first real spike. Flows then settled into a $1–3 billion band, with telecom (NTT Docomo’s stake in Tata Teleservices) and steel (JFE’s investment in JSW) among the larger cheques, until 2016 delivered the series high of $5.78 billion. Even so, the cumulative total from 2000 to 2022 stood at $38.45 billion, 6.14 per cent of all FDI equity into India and good for fifth place, with automobiles (18 per cent), services (14 per cent) and pharmaceuticals (12 per cent) the leading sectors.

Seen against the recent historical trend, the Q1 FY27 figure of $5.71 billion in a single quarter is striking. It is close to the best full year in the 25-year record. The pattern has shifted from episodic, deal-led spikes towards a broader, sustained build-up of manufacturing and technology capital.
