AGREEMENT BETWEEN THE INTERNATIONAL ATOMIC ENERGY AGENCY, THE GOVERNMENT OF JAPAN AND THE GOVERNMENT OF THE UNITED STATES OF AMERICA FOR THE APPLICATION OF SAFEGUARDS BY THE AGENCY TO THE BILATERAL AGREEMENT BETWEEN THOSE GOVERNMENTS CONCERNING CIVIL USES OF ATOMIC ENERGY

　WHEREAS the Government of the United States of America (hereinafter called the "United States") and the Government of Japan (hereinafter called "Japan") have been co-operating on the civil uses of atomic energy under their Agreement for Cooperation of 16 June 1958, as amended (hereinafter called the "Agreement for Cooperation"), which requires that equipment, devices and materials made available to Japan by the United States be used solely for peaceful purposes and establishes a system of safeguards to that end; and

　WHEREAS the Agreement for Cooperation reflects the mutual recognition by the two Governments of the desirability of arranging for the International Atomic Energy Agency (hereinafter called the "Agency") to administer such safeguards as soon as practicable; and

　WHEREAS the Agency is, pursuant to its Statute and the action of its Board of Governors, now in a position of apply safeguards to certain equipment, devices and materials covered by and existing agreement between Member States in accordance with the Agency's safeguards procedures set forth in Agency document INFCIRC/26, approved by the Board on 31 January 1961 (hereinafter called the "Safeguards Document"); and

　WHEREAS the two Governments have reaffirmed their desire that equipment, devices and materials supplied by the United States under the Agreement for Cooperation or produced by the use of such equipment, devices and materials or otherwise subject to that Agreement shall not be used for and military purpose and, accordingly, have requested the Agency to apply the Agency's safeguards to such equipment, devices and materials as hereinafter set forth insofar as the Agency has appropriate provisions to do so; and
