<P> Under the treaty, both parties assumed an obligation to maintain and develop their capacities to resist armed attack in common and to assist each other in case of armed attack on territories under Japanese administration . It was understood, however, that Japan could not come to the defense of the United States because it was constitutionally forbidden to send armed forces overseas (Article 9). In particular, the constitution forbids the maintenance of "land, sea, and air forces ." It also expresses the Japanese people's renunciation of "the threat or use of force as a means of settling international disputes". The scope of the new treaty did not extend to the Ryukyu Islands, but an appended minute made clear that in case of an armed attack on the islands, both governments would consult and take appropriate action . Unlike the 1951 security pact, the new treaty provided for a ten - year term, after which it could be revoked upon one year's notice by either party . </P> <P> Article 6 of the treaty contains a Status of Forces Agreement on the stationing of United States forces in Japan, with specifics on the provision of facilities and areas for their use and on the administration of Japanese citizens employed in the facilities . </P> <P> The Agreed Minutes to the treaty specified that the Japanese government would be consulted prior to major changes in United States force deployment in Japan or to the use of Japanese bases for combat operations other than in defense of Japan itself . Also covered are the limits of the two countries' jurisdictions over crimes committed in Japan by United States military personnel . </P> <P> The Mutual Security Assistance Pact of 1954 initially involved a military aid program that provided for Japan's acquisition of funds, materiel, and services for the nation's essential defense . Although Japan no longer received any aid from the United States by the 1960s, the agreement continued to serve as the basis for purchase and licensing agreements ensuring interoperability of the two nations' weapons and for the release of classified data to Japan, including both international intelligence reports and classified technical information . </P>
