Hell will freeze over before Japan sells plutonium to North Korea or China. However, it's easy to imagine Japan having their own covert nuclear program (and it's probably a wise decision on their part).

Oh I don't think Japan would sell plutonium to North Korea or a rogue state. I don't think that at all - what I do think is that it may have been pilfered.
