Poland‑Japan defence pivot

Japan and Poland used Donald Tusk’s April 15 visit to Tokyo to raise ties to a comprehensive strategic partnership and put defense closer to the center of the relationship. (mofa.go.jp) Tusk met Japanese Prime Minister Sanae Takaichi in Tokyo on April 15 after Japan and Poland had already signed a 2025-2029 action plan through their foreign ministers on February 28, 2025. The new joint statement says the two governments are launching “a new phase” of cooperation. (mofa.go.jp 1) (mofa.go.jp 2) Japan’s side of the shift is legal as well as diplomatic. Its Acquisition, Technology and Logistics Agency says Tokyo revised the Three Principles on Transfer of Defense Equipment and Technology on December 22, 2023, and then widened rules again on March 26, 2024 for finished products tied to joint programs. (mod.go.jp) Those rules matter because Japan had long kept arms exports tightly constrained. The foreign ministry says the current framework permits transfers when they contribute to peace, international cooperation, or Japan’s own security, while still requiring government control over end use and re-transfer. (mofa.go.jp) Poland has been one of Europe’s fastest-growing defense buyers since Russia’s full-scale invasion of Ukraine, and Japan has been looking for partners beyond its traditional U.S.-centered supply chain. Reuters reported on April 15 that Warsaw is interested in working with Tokyo on anti-drone and electronic-warfare systems. (reuters.com) (defensenews.com) One concrete example is drones. Defense News reported that Poland’s WB Group signed a tentative deal last year with Japanese aircraft maker ShinMaywa, a sign that the relationship is moving from political language toward industrial projects. (defensenews.com) The April 15 Japan-Poland statement also linked Europe’s security and Asia’s security in unusually direct language. It says the two leaders see the security of the Euro-Atlantic and Indo-Pacific regions as “inseparable” and opposed attempts to change the status quo by force or coercion. (mofa.go.jp) That language extended to the Taiwan Strait. Taiwan’s foreign ministry said on April 16 that the Japan-Poland statement had reiterated the importance of peace and stability across the strait and support for peaceful resolution through dialogue. (mofa.gov.tw) The backdrop is pressure from two directions at once: Russia’s war in Ukraine and rising military tension around China. In the same statement, Takaichi and Tusk condemned Russia’s aggression against Ukraine and voiced concern about growing military cooperation between Russia and North Korea. (mofa.go.jp) The result is not a formal alliance, and neither government announced a signed weapons contract on April 15. But the documents, the export-rule changes, and the early drone and electronic-warfare talks show Tokyo and Warsaw building a defense relationship that would have been much harder for Japan to pursue even two years ago.
