August 30, 2025 12:00 PM IST First published on: Aug 30, 2025 at 12:00 PM ISTPrime Minister Narendra Modi’s eighth visit to Japan for the annual summit is significant. This is his first such summit with Prime Minister Ishiba Shigeru, though the two have met on the sidelines of the East Asia Summit (EAS) and the G7. Ishiba currently faces a political deficit, having lost the majority in both the lower and, more recently, the upper houses of the Japanese parliament. Yet, efforts to oust him from the leadership of the ruling Liberal Democratic Party (LDP) remain muted, perhaps because few wish to shoulder the burden of managing a turbulent relationship with a rampaging US administration.For India and Japan, both Quad partners, this summit provides an opportunity to assess the regional situation and the future of the Quad, as well as their respective engagement with the US, which is discomfiting for both. They reiterated their commitment to continue the Quad arrangement, but in the absence of a clear signal from the US, the next Quad summit remains uncertain. It may, therefore, be timely for India, Japan, and Australia to convene their own summit, perhaps on the sidelines of the upcoming EAS in Malaysia this October, to reaffirm their shared commitments.AdvertisementEconomically, both India and Japan remain targeted by US tariffs and related measures. Despite having reached certain agreements, Japan continues to tread cautiously, while India is showing greater resolve in the face of tariffs, sanctions, and the absence of a comprehensive trade deal. In this context, the need for closer India-Japan cooperation has never been more urgent, and this was clearly reflected in the visit.Economic collaboration, traditionally the main pillar of the India-Japan partnership, is reinforced with efforts to boost bilateral trade beyond the current level of $23 billion to offset potential losses in the US market. Indian imports are about $18 billion and exports $5 billion. Japan announced a decision to double its investment in India: The earlier target of JPY 5 trillion set in 2022 will now rise to JPY 10 trillion by 2035. This major boost instills confidence and ensures continuity in Japanese investment decisions. This will likely augment trade. India and Japan launched the Economic Security Initiative to promote supply chain resilience in strategic sectors such as semiconductors, clean energy, telecom, pharmaceuticals, critical minerals as well as new and emerging technologies. They also issued an Economic Security Fact Sheet as an illustrative list of suggested cooperation.Of particular significance is the growing depth and diversity of Japanese investment in India, spanning these sectors. For instance, while Japan remains cautious about EV adoption domestically, Maruti Suzuki recently inaugurated an EV plant in India in the presence of Modi. These new investment plans are expected to bring more Japanese businesses and visitors to India.AdvertisementAmid global economic uncertainty, India offers Japanese companies a rare flicker of hope. During recent engagements that I had in Japan, there was widespread enthusiasm among business leaders for deeper cooperation with India in the coming years. In this context, Ishiba, while inaugurating the ninth Tokyo International Conference on African Development (TICAD 9) in Yokohama on August 20, announced Japan’s intent to work with the Indian Ocean-Africa region to promote economic development and maintain a free and open Indo-Pacific — where India would play a pivotal role. The trilateral cooperation between India, Japan, and Africa, an idea championed since 2016, is now evolving into a concrete government policy.Also Read | What India should and should not do to combat Trump’s tariffsJapan’s approach toward Africa is not to increase ODA but to support Japanese companies in expanding trade, investment, and supply chains for critical minerals, possibly working in partnership with Indian companies. Under this emerging framework, African countries could supply critical minerals for beneficiation and initial investment, after which they would be sent to India for processing. The processed materials could then support Japanese industries in semiconductors, climate-friendly technologies, defence electronics, and space. This would help build resilient supply chains, reducing dependence on China. While this concept has received government endorsement and was included in the India-Japan communiqué, the responsibility now lies with the business communities to operationalise it. A supportive MoU to advance cooperation in supply chain resilience for critical minerals, including through the development of processing technologies, joint investments for exploration and mining and efforts for stockpiling critical minerals, was agreed upon.The long-pending bullet train project is also showing signs of renewed coherence between Indian and Japanese stakeholders. Instead of supplying technology from the date of the original agreement, Japan is now prepared to provide the latest E10 Shinkansen coaches as they are introduced domestically. Should the bullet train commence operations earlier, it will initially use the E5 or Indian-made coaches, a move that could pave the way for an expanded network of fast trains in India based on Japanese models, though not necessarily as full Shinkansen lines. These are envisaged in the mobility partnership.most readDefence and strategic cooperation have yielded tangible results during this visit. The Unicorn antennas earlier agreed upon are reportedly ready and will soon be provided to India. Negotiations are also underway for joint R&D and production in India, particularly in defence electronics. Naval cooperation is likely to deepen as Japanese companies gain confidence in supplying armaments, potentially including warship collaboration, as Japan recently initiated with Australia for six vessels.While Japan is prepared to collaborate with India across the Indian Ocean and in Africa, its willingness to work jointly in ASEAN remains limited. Extending similar efforts to ASEAN, through partnerships with Indian companies, could unlock new supply chains, expand India’s economic footprint, and elevate regional trade relations.The writer, a former diplomat, is author of The Mango Flavour: India & ASEAN After 10 years of the AEP
