During the past few years, public opposition to Japan's nuclear power program has increased in reaction to a series of accidents at Japanese nuclear plants, including a March fire and explosion at the Tokai-mura reprocessing plant.

Other problems for Japan's nuclear power program have included rising costs of nuclear reactors and fuel, the huge investments necessary for fuel enrichment and reprocessing plants, several reactor failures, and the question of nuclear waste disposal. As of , Japan ranked third worldwide in installed nuclear capacity, behind the United States and France.

The Fukushima Daiichi nuclear disaster was the largest nuclear disaster since Chenobryl in To enhance its energy security, the government advocates uranium and plutonium recovery through reprocessing of spent fuel.

The Power Reactor and Nuclear Fuel Development Corporation PNC operates a reprocessing plant with an annual capacity of 90 tons but a larger reprocessing plant, Rokkasho-Mura, with a capacity of tons per year, originally planned for , isthe first reprocessing plant in an NPT non-nuclear weapon state.

Reprocessing is expensive and costs can quickly rise with new safety requirements and the development of new technologies. Japan also is interested in recycling recovered plutonium. In , Japan began, in two prefectures, a controversial mixed-oxide utilization plan, which involves burning a highly toxic mix of plutonium and uranium on a commercial scale.

Tokyo pledged in that it would adhere to the principle of not retaining surplus plutonium. As of December , the total inventory of separated plutonium managed by Japan was Japan's nuclear efforts were disrupted in April when a B raid damaged Nishina's thermal diffusion separation apparatus.

Some reports claim the Japanese subsequently moved their atomic operations to Konan [Hungnam, now part of North Korea]. The Japanese may have used this facility for making small quantities of heavy water. The Japanese plant was captured by Soviet troops at war's end, and some reports claim that the output of the Hungnam plant was collected every other month by Soviet submarines.

There are indications that Japan had a more sizable program than is commonly understood, and that there was close cooperation among the Axis powers, including a secretive exchange of war materiel. The German submarine U, which surrendered to US forces in May , was found to be carrying kilograms of Uranium oxide destined for Japan's own atomic program.

The oxide contained about 3.
