Japanese Prime Minister Sanae Takaichi on 3 July 2025 declared that India and Japan are committed to deepening their partnership 'as brother and sister,' following bilateral talks with Prime Minister Narendra Modi at Hyderabad House in New Delhi. The two leaders identified three priority areas to anchor their cooperation as both nations prepare to mark 75 years of diplomatic relations in 2027.

Key Developments from the Summit

Addressing a joint press conference after the talks, Takaichi expressed gratitude for India's hospitality and warmly acknowledged Modi's reference to her as a 'beautiful younger sister.' She said the sentiment captured the spirit of the bilateral relationship. 'Japan and India must leverage our respective strengths to become stronger and more prosperous together,' she said. 'In the midst of international affairs in disarray, the establishment of such an inter-complementary cooperative relationship has become ever more important.'

The two leaders reaffirmed the breadth of their shared agenda and agreed to focus cooperation on three central pillars: strategic alignment, economic partnership, and people-to-people ties ahead of the diplomatic anniversary.

Strategic Cooperation and Indo-Pacific Alignment

On the strategic front, Takaichi highlighted convergence between Japan's updated Free and Open Indo-Pacific (FOIP) framework — which she said now emphasises self-reliance and resilience — and Prime Minister Modi's MAHASAGAR initiative, described as the Great Ocean Initiative, which seeks to help Indian Ocean nations defend their sovereignty and maritime space through their own efforts. 'This is perfectly aligned with FOIP,' Takaichi said.

Maritime security cooperation emerged as a centrepiece of the talks. Takaichi announced that a destroyer from Japan's Maritime Self-Defence Force and an Indian Navy vessel are scheduled to conduct a joint exercise during her visit. Both sides also agreed to enhance exercises in the Indian Ocean, expand naval maintenance, repair, and overhaul cooperation, and strengthen equipment collaboration under the Make in India framework.

Economic Vision and Viksit Bharat

Takaichi drew an explicit link between Modi's Viksit Bharat vision — India's goal of becoming a developed nation by 2047 — and Japan's own growth ambitions, describing the two as complementary. She said both countries share the goal of making their nations stronger through 'future-focused investments,' signalling that economic cooperation will be a key driver of the relationship's next phase.

This comes amid a broader global realignment, with major democracies seeking to build supply-chain resilience and reduce dependencies on single-source economies. India and Japan have been deepening industrial ties through existing frameworks, and Thursday's summit is expected to add further momentum to joint manufacturing and infrastructure initiatives.

75th Anniversary and the Road Ahead

With 2027 marking 75 years of India-Japan diplomatic relations, Takaichi framed the current moment as a historic inflection point. 'I would like to seize this opportunity to further bring closer together the people of our two countries,' she said. Under the India-Japan Special Strategic Global Partnership, she added, the relationship is moving into 'a new phase.' She concluded by extending an invitation to Modi to visit Japan for the next round of talks.

The summit signals that both governments view the bilateral relationship not merely as a regional arrangement but as a structural pillar of the emerging Indo-Pacific order.
