Japan opens defence supply chains

Japan has opened the way for broad overseas weapons sales, its biggest defence-export rule change in decades. (taipeitimes.com) Tokyo approved the revision on April 21, 2026, removing five export categories that had confined most transfers to rescue, transport, warning, surveillance and mine-sweeping equipment. Ministers and officials will now judge proposed sales case by case. (taipeitimes.com) Japan kept its Three Principles on Transfer of Defense Equipment and Technology, which still bar transfers to countries involved in conflict and require controls on re-export and end use. The government’s official guidelines say transfers may be permitted when they contribute to Japan’s security through joint development, production, parts or services with security partners. (cas.go.jp) This is the next step after earlier loosening. Japan revised the Three Principles on December 22, 2023, and on March 26, 2024, separately allowed transfers of finished products from the Global Combat Air Programme to countries beyond the core partner countries. (mod.go.jp) The policy shift comes as Japan tries to keep more defence production alive at home and tie it to allied manufacturing networks. Japan and the United States said on April 14 that their defence-industry talks had entered a “concrete implementation phase,” including missile co-production discussions on the AIM-120 AMRAAM and faster output for the SM-3 Block IIA and PAC-3 MSE. (mod.go.jp) Europe is moving in the same direction with Tokyo. At the first European Union-Japan Defence Industry Dialogue on April 17, officials said both sides had a “strong shared interest” in more resilient defence supply chains, including dual-use sectors that serve both civilian and military markets. (europa.eu) Potential buyers are already surfacing. Reuters reported that officials and diplomats said countries from Poland to the Philippines are exploring procurement options, and one early deal could involve used Japanese warships for Manila. (kesq.com) The Philippines has built the legal plumbing for that kind of deal over the past year. Japan’s Foreign Ministry said the Japan-Philippines Reciprocal Access Agreement entered into force on September 11, 2025, and the two countries signed an Acquisition and Cross-Servicing Agreement in Manila on January 15, 2026. (mofa.go.jp 1) (mofa.go.jp 2) Prime Minister Sanae Takaichi defended the change by saying partner countries that support each other with defence equipment are necessary. China’s Foreign Ministry said it was “deeply concerned,” and Xinhua said Beijing warned against what it called a return to Japanese militarism. (taipeitimes.com) (english.scio.gov.cn) Japan’s export rules now cover more than selling hardware abroad. They give Tokyo a way to trade production capacity, parts supply and industrial access with countries it already treats as security partners. (cas.go.jp) (europa.eu)
