Seventy-five years of diplomacy, and the bond is still building. Prime Minister Narendra Modi on Wednesday, October 7, 2026, responded warmly to Japanese Prime Minister Sanae Takaichi on X, calling her July 2026 visit to India 'unforgettable' and expressing confidence that bilateral relations will reach 'a new height' as both nations mark the 75th anniversary of their diplomatic ties. Writing in both Hindi and Japanese — a rare dual-language gesture that itself signals the depth of the relationship — Modi told Takaichi: 'Your India visit in July this year will remain unforgettable for me too. This has further strengthened the India-Japan partnership.' He added that both countries 'will continue to work together for global peace, stability and prosperity, taking their longstanding friendship further forward.'

A July visit that left a mark

PM Takaichi's July 2026 visit to New Delhi was the latest in a sustained run of high-level exchanges between Asia's two largest democracies. The visit evidently produced enough momentum that both leaders are still publicly reflecting on it months later — a sign that the diplomatic homework done during the trip has carried into ongoing work rather than fading into the usual post-summit silence.

The weight of 75 years

India and Japan established formal diplomatic relations in 1952, making 2027 the formal golden anniversary year — though the 75th milestone being invoked here points to a broader commemorative arc the two governments are already framing. Over those decades the relationship has evolved from post-war goodwill into one of the most structured partnerships in the Indo-Pacific: covering defence equipment cooperation, high-speed rail infrastructure, Official Development Assistance, semiconductor supply chains, and the Quad framework alongside the United States and Australia. Modi's choice to write a portion of the message in Japanese — '高市首相、誠にありがとうございました' ('Prime Minister Takaichi, thank you sincerely') — is not incidental. It is a deliberate diplomatic signal, underscoring personal warmth and respect for Japan's language and culture that has characterised Modi's engagement with Tokyo across successive prime ministers.

Indo-Pacific framing and what the 75th year could unlock

The phrase 'global peace, stability and prosperity' is the operational vocabulary of the Quad and of India-Japan joint statements — shorthand for a rules-based Indo-Pacific order, maritime security in the South and East China Seas, and supply-chain resilience away from single-point dependencies. By invoking it in a personal exchange, Modi signals continuity: the strategic architecture being built between New Delhi and Tokyo is not contingent on any single leader's tenure. The 75th anniversary milestone gives both governments a natural diplomatic hook — expect joint commemoration events, possibly a fresh five-year roadmap, and enhanced people-to-people exchanges — all of which tend to generate binding commitments that outlast the celebratory year itself. Seventy-five years in, the relationship still has room to run — and both capitals are clearly intent on proving it.
