U.S. and Japan Mutual Defense Assistance Agreement
The Government of the United States of America and the Government of Japan,
Desiring to foster international peace and security, within the framework of the Charter of the United Nations, through voluntary arrangements which will further the ability of nations dedicated to the purposes and principles of the Charter to develop effective measures for individual and collective self-defense in support of those purposes and principles;
Reaffirming their belief as stated in the Treaty of Peace with Japan signed at the city of San Francisco on September 8, 1951  that Japan as a sovereign nation possesses the inherent right of individual or collective self-defense referred to in Article 51 of the Charter of the United Nations;
Recalling the preamble of the Security Treaty between the United States of America and Japan, signed at the city of San Francisco on September 8, 1951,  to the effect that the United States of America, in the interest of peace and security, would maintain certain of its armed forces in and about Japan as a provisional arrangement in the expectation that Japan will itself increasingly assume responsibility for its own defense against direct and indirect aggression, always avoiding armament which could be an offensive threat or serve other than to promote peace and security in accordance with the purposes and principles or the Charter of the United Nations;
Recognizing that, in the planning of a defense assistance program for Japan, economic stability will be an essential element for consideration in the development of its defense capacities, and that Japan can contribute only to the extent permitted by its general economic condition and capacities;
Taking into consideration the support that the Government of the United States of America has brought to these principles by enacting the Mutual Defense Assistance Act of l949, as amended, and the Mutual Security Act of 1951, as amended,  which provide for the furnishing of defense assistance by the United States of America in furtherance of the objectives referred to above; and
