India-Japan Ties & QUAD

India-Japan Ties & QUAD: A Strategic Pivot with Uneven Ground Realities

On October 27, 2025, Japan’s first woman Prime Minister, Sanae Takaichi, pledged to push defense spending beyond 2% of GDP and strengthen strategic engagements within the QUAD alliance. What stands out is her administration’s deviation from Japan’s post-World War II pacifism — a profound shift rooted in constitutional constraints under Article 9.

Japan’s Defense Shift: Breaking from a Decades-Old Paradigm

The proposed rise in Japan's defense expenditure signals an unprecedented move. Japan has long defined its military capabilities as strictly defensive, shaped by the trauma of WWII. Article 9 of its Constitution prohibits offensive military actions, and even the Self-Defense Forces (SDF) have operated within carefully calibrated limits. Not anymore.

Sanae Takaichi’s push to operationalize Japan as a "normal power" aligns with her commitment to modernizing the SDF, revisiting constitutional clauses that curb military action, and fortifying QUAD alliances—India at the forefront. This policy shift mirrors intensified geopolitical tensions from China's expansionist activities in the South China Sea and North Korean missile tests.

While Takaichi’s assertive stance contrasts with earlier leaders’ temperate approach, it builds on the groundwork laid by Shinzo Abe, who relentlessly advocated for Japan’s global security role through the ‘Proactive Contributor to Peace’ doctrine. Yet the scale of her ambitions raises critical questions about execution in a country culturally attuned to restraint.

Institutional Machinery Behind India-Japan’s Strategic Partnership

The bilateral framework between India and Japan is structured meticulously under the Special Strategic and Global Partnership (2014). Three institutional pillars stand out:

• The 2+2 Ministerial Dialogue, ensuring alignment between foreign and defense initiatives.
• Joint defense exercises—such as Dharma Guardian and JIMEX, complemented by QUAD’s Malabar drills.
• The Acquisition and Cross-Servicing Agreement (ACSA) (2020), enabling reciprocal logistics support in the Indo-Pacific.

The partnership has also woven economic nodes into defense strategies. Japan’s investment commitments in India exceed $40 billion since 2014, aiding sectors like high-speed rail and smart cities. Moreover, the India-Japan Action Plan aims to facilitate cross-skilling of 500,000 professionals, including 50,000 Indians, underscoring workforce interdependence.

What the Numbers Reveal: Trade, Defense, and Unrealized Potential

The bilateral trade figures tell an uneasy story: total trade between India and Japan amounted to a modest $21.5 billion in 2024, growing at 6% annually compared to ASEAN states, which witnessed double-digit growth in their trade figures with Japan. Japan remains India’s fifth-largest investor, but India's exports have consistently lagged behind.

In defense, items like unmanned aerial vehicles and critical surveillance equipment are set to be co-developed under India’s ‘Atmanirbhar Bharat’ initiative. However, the volume of defense tech transfer raises questions about Japan’s alignment with its stated QUAD goals. A glaring bottleneck lies in the Mumbai-Ahmedabad bullet train project, which suffers extensive delays, primarily due to land acquisition challenges and regulatory quagmires.

The touted Resilient Supply Chain Initiative (RSCI), designed to reduce dependencies on China, faces headwinds as Japanese businesses hesitate over India's complex labor laws and infrastructure deficits. While frameworks exist, tangible outcomes are uneven.

Uncomfortable Questions: Asymmetry, Coordination, and Strategic Autonomy

Despite the ambitious rhetoric surrounding QUAD, uncomfortable frictions persist, especially between India and Japan. Japan’s strategic position as a close ally of the United States presents an institutional asymmetry. India remains committed to strategic autonomy, often pursuing routes independent of Western consensus. This divergence influences QUAD’s collective posture on China, rendering coordinated action cumbersome.

Economic disparity further complicates matters. Japan’s advanced manufacturing and robotics expertise remain unmatched, whereas India’s strengths lie in IT and digital services. Efforts to synergize such contrasting strengths — through initiatives like 5G collaboration — lack robust policy mechanisms for R&D alignment.

There is also legitimate skepticism over Japan's internal ability to sustain its recalibrated defense goals. Constitutional reform faces domestic backlash, while a defense budget hike beyond 2% of GDP must overcome fiscal constraints in a country grappling with demographic decline and a shrinking workforce. Political will is clear. Institutional hurdles, however, loom large.

Comparative Anchor: South Korea's Strategic Play

Japan’s defense modernization efforts draw inevitable comparisons with South Korea’s military transformation under Moon Jae-In. By increasing its defense spending to 2.7% of GDP in 2018 and initiating offensive platform upgrades (F-35 fighter jets, submarine-launched ballistic missiles), Korea successfully balanced against threats from China and North Korea while integrating seamlessly into US-led alliances.

However, unlike South Korea’s clear US alignment, Japan faces strategic fluidity in regions dominated by varying QUAD perspectives. India’s differing priorities, particularly its border skirmishes with China, complicate a unified Indo-Pacific doctrine.
