The Pentagon kept nuclear weapons on Japanese soil after World War II despite Tokyo’s opposition to the development or presence of such arms, this according to a report by a group of American scientists. Citing an unnamed Japanese source, the Bulletin of the Atomic Scientists said the United States stored the weapons on Chichi-jima, some 500 miles southeast of the Japanese mainland, and Iwo Jima, 760 miles south-southeast of Tokyo. The article, posted on the publication’s website, said the two islands became nuclear bases in the 1950s and that Chichi-jima continued to house warheads with their nuclear material until 1965. Actual nuclear weapons were pulled from Iwo Jima at the end of 1959.
