Germany–Japan Relations:
Implications of Chancellor Merz’s Visit
Chancellor Friedrich Merz’s visit to Japan on 28–29 October 2026 and meeting with Prime Minister Sanae Takaichi strengthened a partnership increasingly organised around economic security and defence . The principal significance is the attempt to connect industrial cooperation with strategic resilience—though turning agenda into reduced dependencies and usable military capabilities still requires demonstration.
✓ Substantive Expansion: Explicitly links Euro-Atlantic & Indo-Pacific security while launching AI, mineral, and high-tech dialogues.
! Decisive Test is Implementation: Declarations establish an agenda; reduced dependencies and military capabilities still require proof.
⚡ Commercial Friction: Tokyo raised strong concerns over the EU’s Industrial Accelerator Act .
An Established Partnership Gains Depth
The October 2026 visit builds on existing legal and economic institutions that already provide practical foundations for closer bilateral cooperation.
EU–Japan Economic Partnership Agreement (EPA)
Operating since February 2019, the EPA anchors bilateral trade and investment governance between the European Union and Japan.
Acquisition and Cross-Servicing Agreement (ACSA)
Entered into force on 12 July 2024, facilitating reciprocal military supplies and services between German and Japanese forces.
Connecting Euro-Atlantic & Indo-Pacific Security
Analytically, the new leaders’ statement treats pressures in Europe and Asia as interconnected challenges to sovereignty, secure trade, and the use of force .
Economic Security Links Trade, Tech & Defence
Filter the 12 cooperation areas established across the Joint Leaders’ Statement and the separate Economic Security and Advanced Technology declarations.
Critical Minerals
Diversification of critical mineral supplies, recycling initiatives, and coordinated stockpiling.
Supply-Chain Monitoring
Joint monitoring mechanisms to reduce vulnerability to disrupted supplies and economic pressure.
Investment & Tech
Closer coordination over investment screening and sensitive technology protection.
High-Level AI Dialogue
Establishes a dedicated high-level bilateral dialogue on artificial intelligence governance and cooperation.
Semiconductors & Maritime
Identifies semiconductors and maritime industries as priority sectors for industrial cooperation.
Space Cooperation
Develops bilateral scientific and technological collaboration across the space domain.
Fusion Energy
Expands advanced research collaboration on next-generation fusion energy technologies.
Clean Hydrogen & R&D
Advances clean hydrogen technology and institutional research exchanges.
Fighter-Aircraft Study
Announced an exploratory examination of possible cooperation in fighter-aircraft development.
Keen Sword Exercise
Deployment of more than 100 Bundeswehr personnel participating in Exercise Keen Sword.
Uncrewed & Cyber Ops
Prioritises uncrewed systems, cybersecurity, and operational cooperation across theatres.
Cross-Border Production
Stated preference for cooperative production across borders—contingent on market access rules.
Where Political Announcements Meet Practical Constraints
The summit declarations establish an ambitious agenda, yet their capacity to reduce concentrated dependencies or improve military capabilities still requires demonstration.
1. Fighter-Aircraft Development
Merz announced an examination of possible cooperation in fighter-aircraft development.
Does not establish a joint aircraft programme, a procurement commitment, or a mutual-defence obligation.
2. Economic Security & De-Risking
Reduce vulnerability to disrupted supplies and economic pressure via complementary capabilities and diverse partnerships.
Depends on commercially viable projects, financing, and alternative production capacity—not declarations alone.
Comparing Political & Agenda Ambition against Demonstrated Operational / Commercial Maturity as of October 2026:
Prime Minister Takaichi raised strong concerns about the EU’s Industrial Accelerator Act and called for reciprocal consideration of trusted partners in strategic industrial support .
Bottom Line: Policies intended to strengthen European industry can complicate cooperation with Japan unless cross-border preferences influence eligibility rules, investment decisions, and market access .
Parallel Diplomacy:
Merz in Tokyo, Steinmeier in China
Chancellor Merz’s summit in Tokyo took place during Federal President Frank-Walter Steinmeier’s concurrent visit to China, scheduled for 27–31 October 2026 .
Read together, the two visits suggest a German approach combining engagement with Beijing and stronger alternative partnerships.
Analytical Boundary: This is an analytical interpretation, rather than evidence that Germany has resolved the trade-offs between commercial exposure and strategic risk.

Chancellor Merz’s Visit to Tokyo & Parallel Diplomacy
Produced the Joint Leaders’ Statement and separate declarations on Economic Security and Advanced Technology. Concurrently, President Steinmeier visited China (27–31 Oct), highlighting Germany’s dual approach of engaging Beijing while building stronger alternative partnerships.
4 Litmus Tests of Implementation
Implementation is the decisive test. The strongest evidence of substantive progress will require four concrete outcomes:
Funded Industrial Projects
Moving beyond declarations to commercially viable, financed projects in semiconductors, AI, space, and clean energy.
Demonstrably Diverse Supplies
Tangible reduction in concentrated dependencies through alternative production capacity, mineral recycling, and stockpiling.
Sustained Military Interoperability
Translating Keen Sword participation (>100 Bundeswehr personnel) and exploratory fighter studies into usable military capabilities.
Reciprocal Access for Firms
Ensuring EU industrial support rules (Industrial Accelerator Act) reflect reciprocal consideration for trusted partners.
