This article examines the history of Japan's nuclear program, its current stance on nuclear weapons, and international opinion on the matter. Japan has maintained a strong commitment to non-proliferation and disarmament since signing the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in 1968. Although Japan does not possess any actual nuclear weapons, it does possess some limited capabilities for producing them. The Japanese government officially maintains that it will never possess or develop any type of nuclear weapon under any circumstances and is actively involved with various international organizations such as IAEA which promote peaceful uses of atomic energy while discouraging any type of military use thereof. The majority of international opinion is largely supportive towards this decision, although there may be some disagreement among certain nations regarding this issue.
