Japan and India share a relationship that goes far beyond modern politics. Their connection combines ancient Buddhist links, economic cooperation, infrastructure, technology, defence and a shared interest in a peaceful Indo-Pacific.

Today, India and Japan describe their relationship as a Special Strategic and Global Partnership. In 2025, Prime Minister Narendra Modi and then-Japanese Prime Minister Shigeru Ishiba agreed to deepen cooperation in defence, investment, technology, AI, critical minerals, space and people-to-people exchanges.

Important current update: Japan is now led by Prime Minister Sanae Takaichi. She visited India in July 2026 for the 16th India–Japan Annual Summit, where she and Modi discussed the future of the partnership.

🇯🇵 Japan — Quick Facts

🕉️ The Ancient Connection Between India and Japan

The India–Japan relationship is not something that started only with modern governments.

One of its deepest connections is Buddhism.

Buddhist teachings that originated in India travelled across Asia through different routes and eventually became deeply influential in Japan.

This historical connection created a cultural bridge between the two countries.

Even today, Buddhist philosophy, temples and spiritual traditions provide an important connection between Indian and Japanese civilisation.

🤝 Modern Diplomatic Relations

India and Japan established diplomatic relations in 1952.

Over the decades, the relationship expanded from diplomacy into:

• 💰 Trade
• 🏭 Investment
• 🚄 Infrastructure
• 💻 Technology
• 🛡️ Defence
• 🚀 Space
• ⚡ Energy
• 🎓 Education
• 🌏 Indo-Pacific cooperation

The partnership has become especially important over the last decade.

🇮🇳 Narendra Modi and Japan

Prime Minister Narendra Modi has placed considerable importance on India’s relationship with Japan.

Japan has also become an important partner in India’s infrastructure and industrial development.

The two countries hold annual summits and maintain numerous dialogue mechanisms across different sectors. The 2025 summit noted that India and Japan had more than 70 dialogue mechanisms and working groups covering various areas of cooperation.

🚄 Japan’s Biggest Gift to India’s Infrastructure Story?

When Indians hear Japan + India, one project immediately comes to mind:

🚄 Mumbai–Ahmedabad High-Speed Rail

Japan is assisting India with its high-speed rail project between Mumbai and Ahmedabad.

The project uses Japanese Shinkansen technology and is intended to introduce high-speed rail technology on a major Indian route.

For India, this isn’t simply about a faster train.

It represents:

Technology + engineering + infrastructure + India–Japan cooperation.

🏭 Japan and Make in India

Japanese companies have invested in India across several sectors.

These include:

🚗 Automobiles
🔌 Electronics
🏭 Manufacturing
💻 Technology
🏦 Finance
🏗️ Infrastructure

Japanese investment is particularly valuable to India because Japanese companies are known for advanced manufacturing, precision engineering and long-term industrial planning.

💻 India + Japan = Technology Partnership

Technology is becoming one of the most important areas of cooperation.

The two countries have been working together on:

• Artificial intelligence
• Digital technology
• Semiconductors
• Startups
• Research
• Cybersecurity
• Advanced manufacturing

At the 2025 summit, Modi and Ishiba welcomed India–Japan Digital Partnership 2.0 and a Japan–India AI Cooperation Initiative covering AI research, industry–academia collaboration and other areas.

🤖 AI Cooperation

Artificial intelligence is changing the global economy.

India has a large technology workforce and growing startup ecosystem.

Japan has strong capabilities in:

🤖 Robotics
🏭 Automation
🔬 Research
🚗 Advanced manufacturing

Combining these strengths could create opportunities for both countries.

That is why AI and digital cooperation have become important parts of the modern India–Japan relationship.

🛡️ India–Japan Defence Cooperation

Japan and India are also becoming closer in defence and security.

The two countries conduct military exercises and cooperate on maritime security.

Their security relationship includes:

⚓ Naval cooperation
✈️ Air exercises
🪖 Military exchanges
🌊 Maritime security
💻 Cybersecurity
🚨 Disaster relief

India and Japan have also agreed to improve logistics and interoperability between their defence forces.

🌊 Why Is the Indo-Pacific Important?

India and Japan are both major Indo-Pacific countries.

The region includes some of the world’s most important:

• Shipping routes
• Trade networks
• Ports
• Energy routes
• Technology supply chains

India and Japan want the Indo-Pacific to remain free, open, peaceful and stable.

Their cooperation therefore has importance far beyond their two countries.

🇮🇳🇯🇵 The Quad Connection

India and Japan are both members of the Quad, along with:

🇺🇸 United States
🇦🇺 Australia

The Quad discusses cooperation in areas such as:

🌊 Maritime security
💻 Technology
🌏 Regional connectivity
🚨 Disaster response
🏥 Health
🔋 Critical technologies

India and Japan see the Quad as an important platform for Indo-Pacific cooperation.

⚡ Energy Cooperation

Energy security has become increasingly important for both countries.

Japan is a major energy importer.

India is one of the world’s largest and fastest-growing energy markets.

In July 2026, Modi and Japanese Prime Minister Sanae Takaichi discussed strengthening energy resilience, including cooperation on strategic stockpiling and energy security.

This shows that the relationship is expanding beyond traditional trade and infrastructure.

🪨 Critical Minerals

Modern technology requires critical minerals.

These materials are important for:

🔋 Batteries
🚗 Electric vehicles
💻 Electronics
🌞 Renewable energy
🛰️ Advanced technology

India and Japan have agreed to cooperate more closely in this area.

The 2025 summit included a memorandum on mineral resources and efforts to build more resilient supply chains.

🚀 India and Japan in Space

India and Japan are also cooperating in space science.

One important project is the planned LUPEX mission, a joint lunar exploration effort involving ISRO and Japan’s space agency JAXA.

The mission is intended to study the Moon’s polar region.

This is a fascinating example of two Asian countries combining their space capabilities.

🌱 Clean Energy and Climate Cooperation

Both India and Japan are working toward cleaner energy systems.

Cooperation includes areas such as:

🌞 Solar power
🔋 Batteries
⚡ Energy efficiency
🌱 Green technology
🚗 Electric mobility

The countries included clean-energy cooperation among the areas highlighted in their 2025 summit.

🏙️ Japanese Cities and Indian States

An interesting development is the growth of state–prefecture partnerships.

Indian states and Japanese prefectures have begun developing direct relationships for:

🏭 Business
🎓 Education
🌱 Environment
🏗️ Infrastructure
👥 Cultural exchange

The 2025 India–Japan summit highlighted partnerships involving Andhra Pradesh–Toyama, Tamil Nadu–Ehime, Uttar Pradesh–Yamanashi and Gujarat–Shizuoka.

This means India–Japan relations are no longer limited to New Delhi and Tokyo.

🇯🇵 Japan’s Role in India’s Northeast

Japan has also supported infrastructure and development projects in India’s Northeast.

This region is strategically important because it connects India with Southeast Asia.

Better roads, bridges and connectivity can help strengthen India’s Act East Policy.

Japan’s development cooperation therefore has significance not only economically but also strategically.

👨‍🎓 People-to-People Connections

India and Japan are also trying to increase people-to-people links.

These include:
