India Japan relations

1. Introduction

India and Japan share a Special Strategic and Global Partnership, founded on shared democratic values, respect for the rule of law, strategic convergence and mutual commitment to a Free and Open Indo-Pacific (FOIP). Since the establishment of diplomatic relations on 28 April 1952, India Japan relations have evolved into one of India’s most trusted and comprehensive bilateral relationships, encompassing economic cooperation, infrastructure development, defence, technology, connectivity, clean energy and global governance. India Japan Cooperation has therefore emerged as an important pillar of India’s external relations.

Japan has emerged as one of India’s most important development and strategic partners. It is a leading source of Official Development Assistance (ODA), a major investor in India’s manufacturing sector, and a key contributor to flagship infrastructure projects such as the Mumbai–Ahmedabad High-Speed Rail (Bullet Train), Delhi–Mumbai Industrial Corridor (DMIC) and metro rail projects. These initiatives have given India Japan Cooperation a strong developmental and economic dimension and have further strengthened India Japan relations.

The partnership has gained greater strategic significance amid the changing geopolitical landscape of the Indo-Pacific. Both countries cooperate closely through the Quad, G20, G4, East Asia Summit (EAS) and other multilateral forums to promote regional stability, resilient supply chains, maritime security and reform of global governance institutions. This expanding India Japan Cooperation has made India Japan relations increasingly important for regional peace and stability.

Today, India and Japan are natural partners whose relationship is driven by economic complementarity, technological collaboration and shared strategic interests. The partnership is expected to play a pivotal role in advancing India’s Act East Policy, Japan’s Free and Open Indo-Pacific (FOIP) vision, and the broader objective of ensuring a peaceful, prosperous and rules-based Indo-Pacific region. Thus, India Japan relations and India Japan Cooperation are expected to remain central to India’s strategic engagement in the Indo-Pacific.
