Three Principles on Transfer of Defense Equipment and Technology

While maintaining its basic philosophy as a peace-loving nation that conforms to the Charter of the United Nations and the course it has taken as a peace-loving nation, Japan will control the overseas transfer of defense equipment and technology based on the Three Principles on Transfer of Defense Equipment and Technology. Main contents of the Principles are as follows; (1)Clarification of cases where transfers are prohibited (the First Principle) Overseas transfer of defense equipment and technology will not be permitted when: i) the transfer violates obligations under treaties and other international agreements that Japan has concluded, ii) the transfer violates obligations under United Nations Security Council resolutions, or iii) the defense equipment and technology is destined for a country party to a conflict (a country against which the United Nations Security Council is taking measures to maintain or restore international peace and security in the event of an armed attack). (2)Limitation to cases where transfers may be permitted as well as strict examination and information disclosure (the Second Principle) In cases not within (1) above, cases where transfers may be permitted will be limited to the following cases. Those cases will be examined strictly while ensuring transparency. The transfer contributes i) to active promotion of peace contribution and international cooperation, or ii) Japan’s security. Significant cases that require especially careful consideration from the viewpoint of Japan’s security will be examined at the National Security Council (NSC). As for the cases that were deliberated at the NSC, the Government will disclose their information in accordance with the Act on Access to Information Held by Administrative Organs (Law No. 42 of 1999). (3)Ensuring appropriate control regarding extra-purpose use or transfer to third parties (the Third Principle) In cases satisfying (2) above, overseas transfer of defense equipment and technology will be permitted only in cases where appropriate control is ensured. More concretely, the Government will in principle oblige the Government of the recipient country to gain its prior consent regarding extra-purpose use and transfer to third parties.
