Japan Potential Nuclear Superpower


Analysis of the stockpiles of nuclear material available for use in bomb building reveals some surprising results, with Japan’s nuclear potential ranking high in an international comparison thanks to its large nuclear power industry.


As the chart suggests, it takes into account estimates of plutonium stockpiles, whether acquired expressly for the purposes of nuclear armament or for civilian power generation, to build a series of estimates of the potential nuclear stockpiles each nation could build.

Japan also possesses an additional distinction compared to a number of countries shown, in that it has an independent space program.
