Japan has the means, motive, and opportunity to produce nuclear weapons. However, as a matter of long-standing policy, Tokyo has kept its options open, as long as it can rely on the U.S. nuclear umbrella. The perception is widespread that, due to its history as the only country upon which a nuclear weapon has been used, Japan has an innate nuclear allergy that precludes it from going down the path of nuclear proliferation.

This is partially true, but Japanese leaders have also preserved Japan’s nuclear option both by carefully and consistently articulating Japan’s policy in this regard, and by nurturing Japan’s actual capacity to produce and deploy nuclear weapons. In addition to its intrinsic merit, this nuclear latency approach serves to convince the U.S. that it must continually reassure Japan of the credibility of its nuclear umbrella to prevent Japan going nuclear.
