Japan is taking concrete steps to expand its defense partnerships.
On June 16, 2026, Japan's Defense Minister met with his Dutch counterpart in Tokyo, agreeing to begin formal talks on a Defense Equipment and Technology Transfer Agreement (DETTA). This is a significant move that operationalizes Japan's newly overhauled defense export policy, creating a legal pathway for selling completed weapons systems to the Netherlands.
The most direct driver behind this development is a landmark policy change from April 2026. First, Japan revised its 'Three Principles on Transfer of Defense Equipment and Technology,' effectively making exports of finished weapons possible in principle. However, there's a crucial condition: such exports are only allowed to countries that have signed a DETTA with Japan. This self-imposed legal requirement makes the talks with the Netherlands not just a good idea, but a necessity.
Second, this isn't happening in a vacuum. It reflects a broader trend of strengthening security ties between the Euro-Atlantic and Indo-Pacific regions. The Netherlands, under a new defense-forward government, has already demonstrated its commitment by conducting naval patrols near Japan to enforce UN sanctions. These prior actions have built a strong foundation of operational trust, making a formal defense-industrial pact a natural next step.
Third, there are compelling technological and economic incentives for both nations. The Netherlands is a global leader in advanced radar and semiconductor manufacturing technology (home to ASML), while Japan is significantly increasing its defense budget toward 2% of GDP and rebuilding its industrial base. The agreement allows them to build 'trusted-supplier' networks for critical technologies, a shared goal in today's geopolitical climate.
In essence, this meeting is more than a diplomatic handshake. It's a strategic move to construct a legal and industrial bridge between two key allies, driven by recent policy shifts, shared security concerns, and mutual economic interests.
