Japan's policy of basing its nuclear power program on reprocessed plutonium has aroused widespread suspicion that Japan is secretly planning to develop nuclear weapons. This book presents the views of a leading Japanese proponent of the reprocessing policy, Atsuyuki Suzuki, professor of nuclear engineering at Tokyo University; a leading critic, Jinzaburo Takagi, director of the Citizens Nuclear Information Center; and Taewoo Kim, a South Korean specialist who warns that the Japanese nuclear program could lead Seoul to pursue a reprocessing capability of its own.The introduction by Selig S. Harrison analyzes the history of the domestic debate in Japan over the acquisition of nuclear weapons and assesses the possibility of a Japanese nuclear weapons program.
