Japan does not possess nuclear weapons and remains committed to disarmament and non-proliferation, despite initial considerations in the 1950s. The country adopted the Three Non-Nuclear Principles in 1967, which state that Japan will not possess, produce or permit the introduction of nuclear weapons into its territory. However, there have been concerns about a potential secret nuclear program, though no concrete evidence supports this claim. Japan is a signatory of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and has a significant nuclear power industry. The future of Japan's nuclear policy remains uncertain as debates continue over how best to ensure regional stability and global security.
