As geopolitical tensions rise, Delhi and Tokyo are positioning themselves as trusted strategic partners, in an increasingly uncertain world
The optics were carefully choreographed — a ceremonial reception at Rashtrapati Bhavan, a santoor session recalling Takaichi’s days as a college drummer, and Modi’s warm invocation of her as “meri chhoti behen.” But beneath the pageantry lay a substantive recalibration. The two prime ministers stressed the strategic salience of the India-Japan partnership in an increasingly volatile geopolitical environment and agreed to advance cooperation in three priority areas: economic security, energy resilience and technology.
That framing is telling. This is no longer a relationship built primarily on Japanese aid and infrastructure financing, the template of the past two decades. Both governments are now working to reduce vulnerabilities in global supply chains, particularly in semiconductors, critical minerals and advanced manufacturing, and — perhaps most significantly — they signed an agreement on their first joint defence co-development project, the naval radio antenna effort dubbed “Unicorn.” For two countries that have historically kept defence cooperation at arm’s length compared to their economic ties, this is a genuine step-change, one Modi framed as opening a new chapter in defence technology partnership. The China factor hovers over all of it, even if never named outright in the joint statements. Modi and Takaichi discussed the situation in the Indo-Pacific, a region that has witnessed growing Chinese military muscle-flexing, and the drive toward resilient supply chains is explicitly aimed at reducing dependence on China for critical minerals and active pharmaceutical ingredients. Add to this the disruption from West Asia’s conflict — which has exposed vulnerabilities in the movement of critical goods and energy — and the summit reads less like a ceremony and more like risk management between two trading nations trying to insulate themselves from a world of choke points. On technology, the two sides leaned into complementarity rather than competition. Modi’s formulation — that the convergence of Japan’s precision technology and India’s software capabilities would impart new momentum to global AI development — captures the pitch both governments are making to investors: Japan brings hardware and industrial discipline, India brings scale and digital talent.
The Japan-India Economic Forum pulled in over 150 Japanese companies and produced 120 fresh business agreements, alongside pacts spanning clean energy, healthcare and biotechnology. Three takeaways stand out. First, defence cooperation has crossed a symbolic threshold, with Tokyo’s review of its arms-transfer principles opening the door to deeper co-development beyond token gestures. Second, “economic security” has replaced “connectivity” as the organising vocabulary of the relationship — a shift that mirrors how both nations now think about China and West Asia simultaneously. Third, the personal rapport between Modi and Takaichi, still new to her role, suggests continuity of India-Japan warmth across a change of Japanese leadership. The biggest takeaway, however, is that Delhi and Tokyo intend to be each other’s hedge against an unpredictable world — this maiden visit has done its job.
