Why in News
Japan amended its Three Principles on Transfer of Defence Equipment and Technology on April 21, 2026, effectively removing blanket export restrictions and enabling, in principle, the transfer of all categories of defence equipment. India’s MEA welcomed the move as a boost to the Special Strategic and Global Partnership. Simultaneously, Japan proposed co-production of Mogami-class stealth frigates in Indian shipyards, and the 8th India-Japan Army-to-Army Staff Talks were held in Tokyo (April 22–24).
Japan’s Three Principles: What Changed?
Original Framework
Japan’s post-WWII pacifist constitution and three consecutive sets of principles (1967, 1976, 2014) restricted defence exports severely. The 2014 Three Principles allowed limited exports to: allies (US), UN peacekeeping, humanitarian use, and “countries that contribute to Japan’s security.”
April 2026 Amendment
| Aspect | Before (2014 principles) | After (2026 amendment) |
|---|---|---|
| Transfer scope | Limited categories; strict criteria | All defence equipment transferable in principle |
| Countries | Named partners only | Broader framework |
| End-use monitoring | Required | Retained + strengthened |
| Joint development | Limited | Explicitly enabled |
| Re-export | Prohibited without consent | Consent mechanism retained |
Net effect: Japan moves from a whitelist model (only permitted transfers) to a default-permissive model (all transfers permitted unless restricted).
Mogami-Class Stealth Frigates: What Is on Offer
The Ship
The Mogami-class frigate (30FFM class) is Japan’s latest multi-role surface combatant:
| Feature | Detail |
|---|---|
| Displacement | ~3,900 tonnes |
| Length | ~133 metres |
| Speed | 30+ knots |
| Crew | ~90 (highly automated) |
| Mission | Anti-submarine warfare (ASW), surface warfare, mine countermeasures |
| Stealth features | Low radar cross-section hull design |
| Weapons | 127mm gun; vertical launch system; torpedoes; anti-ship missiles |
The Proposal
Japan offered:
- Design transfer: India builds Mogami-class frigates in Indian shipyards
- Selected material supply: Japan supplies critical components/materials
- Technology support: potential for specific technology transfer under oversight
This would make India the first foreign country to co-produce Mogami-class frigates, a significant diplomatic signal.

Why the Partnership Has Been Slow
Despite strategic convergence (both concerned about China’s rise), defence cooperation has faced structural constraints:
- Japan’s constitutional and political reluctance on exports
- India’s preference for technology transfer vs. buying finished products
- Price competitiveness (Japanese equipment expensive)
- India’s strategic autonomy principle, diversifying supply chains
8th India-Japan Army-to-Army Staff Talks (April 22–24, Tokyo)
Topics discussed:
- Enhancing interoperability through bilateral exercises (Dharma Guardian)
- SME (Subject Matter Expert) exchanges
- Disaster response cooperation
- Regional security assessment (Indo-Pacific)
