Tokyo and New Delhi: A Strategic Partnership Reshaping Asia

The strategic environment in Asia is shifting, and the deepening ties between India and Japan lie at the heart of this change. What started as a robust economic link is now broadening into defence, technology, finance, and security, creating a long‑term partnership driven by shared concerns over China’s expanding military and economic reach in the Indo‑Pacific.

Japan’s recent defence moves illustrate this evolution. In March 2026 Tokyo stationed its first long‑range Type‑12 missiles at bases in Kumamoto and Shizuoka, a historic break from its post‑World‑War‑II self‑defence posture. With a range approaching 1,000 km, these missiles can strike parts of mainland China. Japan calls the deployment necessary given a more complex security landscape, while Beijing sees it as a major departure from nearly eight decades of Japanese military restraint.

Beyond defence, the India‑Japan relationship is also advancing economically. At the 16th India‑Japan Annual Summit in New Delhi in July 2026, the two nations announced a yen‑rupee settlement mechanism. This system will let businesses settle trade directly in Japanese yen and Indian rupees, bypassing the US dollar. Currently, Indian‑Japanese trade requires converting yen to dollars and then dollars to rupees, adding costs and exposing firms to exchange‑rate swings. Direct settlement streamlines the process, cuts transaction expenses, and strengthens financial links between the two economies.

India has already set up similar local‑currency arrangements with Russia, the UAE, and Indonesia, but Japan’s involvement is especially noteworthy. It shows that two of Asia’s largest democracies are exploring financial frameworks that offer more flexibility and less reliance on the dollar, without directly challenging its global dominance.

The scale of bilateral trade remains modest—$27.47 billion in FY 2025‑26, with Japan exporting $21.43 billion worth of goods to India—far below India’s trade with the United States or China. Yet the significance of the yen‑rupee initiative lies in its signal: two major Asian economies are demonstrating that dollar intermediation is not essential, even for a portion of their commerce.

Japan’s openness to such financial cooperation is rooted in history. The 1985 Plaza Accord, which coordinated a dollar‑yen devaluation to curb U.S. trade deficits, caused the yen to surge, hurting Japanese exports and contributing to the prolonged stagnation known as the “Lost Decade.” That experience made Tokyo wary of over‑reliance on externally driven currency regimes. Partnering with a fast‑growing economy like India lets Japan deepen economic ties while retaining greater control over its financial interests.

Defence collaboration is also reaching new heights. Japan has proposed local production of its advanced Mogami‑class stealth frigates in India under the Make in India initiative. If realized, this would mark Japan’s first major defence platform transfer to India and one of its most significant defence exports ever. The deal reportedly includes technology transfer, domestic manufacturing, and integration of India’s BrahMos supersonic cruise missile. Building these warships in Indian shipyards would markedly boost India’s naval strength while allowing Japan to expand its defence‑industrial partnerships beyond traditional allies.

The timing aligns with growing anxieties about China’s expanding naval presence in the East China Sea, South China Sea, and the wider Indo‑Pacific. As regional security dynamics shift, India and Japan are bolstering bilateral defence cooperation to preserve a stable balance of power.

Economic ties are expanding just as quickly. Japan has reaffirmed its pledge to invest 10 trillion yen in India over the next decade. The latest summit generated more than 120 new business agreements covering semiconductors, clean energy, artificial intelligence, and advanced manufacturing, reinforcing India’s status as a key long‑term partner for Japanese capital.

Another notable shift is Japan’s evolving investment strategy. Japanese investors are trimming their holdings of U.S. Treasury securities as domestic bond yields rise. Although Japan remains the largest foreign holder of U.S. government debt, higher returns at home are encouraging capital to stay domestically or seek opportunities elsewhere. India’s rapidly growing economy, expanding manufacturing base, and stable policy environment make it an increasingly attractive destination for Japanese investment.

Individually, these developments—a missile deployment, a local‑currency settlement system, defence technology transfers, and rising investment—might appear as routine bilateral steps. Together, however, they point to a broader trend.

India and Japan are steadily constructing a comprehensive strategic partnership grounded in shared security interests, economic resilience, technological collaboration, and supply‑chain diversification. Their cooperation does not aim to form a formal alliance or target any single country; instead, it reflects a common goal: reducing strategic vulnerabilities while fostering a stable, secure, and multipolar Indo‑Pacific.

As China’s influence continues to expand across Asia, the partnership between New Delhi and Tokyo is emerging as one of the defining geopolitical relationships of the decade. By marrying India’s growth potential with Japan’s technological and financial strengths, the two democracies are helping shape a regional order built on resilience, cooperation, and strategic balance.
