The instrument of ratification of the Treaty by Japan was accompanied by a statement by the Government of Japan, a translation of the text of which reads as follows:
“Today the Government of Japan is depositing its instruments of ratification of the Treaty on the Non-proliferation of Nuclear Weapons with the Governments of the United Kingdom, the Soviet Union and the United States, and Japan becomes a party to this treaty.
“Japan, as the only nation to have suffered atomic bombing, has consistently followed a fundamental policy of forsaking nuclear armament and has steadfastly pursued the foreign policy of a nation committed to peace under its peace constitution. On the occasion of the depositing of its instruments of ratification of this treaty, the Government of Japan declares anew to the world this fundamental policy. It firmly believes that Japan’s adherence to this treaty will contribute to stability in international relations, and, in particular, to peace and stability in Asia.
“Japan, as a party to this treaty, is determined hereafter to intensify its efforts to prevent the proliferation of nuclear weapons and to contribute to international cooperation with respect to the peaceful uses of nuclear energy.
“This treaty permits only the nuclear-weapon states to possess nuclear weapons and allows them a special status. The Government of Japan holds the belief that the nuclear-weapon states must rectify this discrimination in the future by totally abolishing their nuclear weapons. To achieve this end, the Government of Japan is determined to make special efforts for the furthering of nuclear disarmament.
“On the basis of these fundamental considerations, the Government of Japan stresses especially the following points:
1. The Government of Japan hopes that as many states as possible, whether possessing a nuclear explosive capability or not, will become parties to this treaty in order to make it truly effective. In particular, it strongly hopes that the Republic of France and the People’s Republic of China, which possess nuclear weapons but are not parties to this treaty, will accede thereto.
2. The Government of Japan urges the nuclear-weapon states, which have special responsibilities for nuclear disarmament, to take concrete nuclear disarmament measures such as the reduction of nuclear arms and the realization of a comprehensive nuclear test ban, in accordance with Article VI of this treaty. It urges the nuclear-weapon states not party to this treaty also to take nuclear disarmament measures.
3. The Government of Japan takes particular note of the declarations in June 1968 of the United Kingdom, the Soviet Union and the United States concerning the security of non-nuclear-weapon states, as well as of Security Council Resolution 255 (1968), and hopes that the nuclear-weapon states will make further efforts towards effective measures for the security of non-nuclear-weapon states. It further urges all states, both nuclear-weapon states and non-nuclear-weapon states, to refrain, in accordance with the Charter of the United Nations, from the threat or use of force in their international relations involving either nuclear or non-nuclear weapons.
4. The Government of Japan is convinced that, for the well-being of all mankind, international cooperation with respect to the peaceful uses of nuclear energy and the peaceful applications of nuclear explosions should be vigorously promoted in accordance with the provisions of this treaty. It considers that peaceful nuclear activities in non-nuclear-weapon states party to the treaty should in no way be hampered by this treaty and also that Japan should not be discriminated against in favor of other states party to the treaty in any aspect of such activities.
5. The Government of Japan appreciates the declarations of the United Kingdom and the United States, both nuclear-weapon states, that they will accept the application of safeguards of the International Atomic Energy Agency to their peaceful nuclear activities. It urges the other nuclear-weapon states to take similar action.
6. The Government of Japan hopes that review conferences, as provided for in this treaty, will continue to be held at regular intervals in order to ensure the appropriate operation of this treaty.”
