Abstract
On May 18, 1948, the Archivist of the United States accessioned from the Foreign Documents Branch of the Central Intelligence Agency a collection of over 30,000 volumes of official records which had been seized in Japan by the United States government. Known as the “World War II collection of seized enemy records: Japan,” these volumes now form part of record group 242 and occupy some 3,450 cubic feet of space in the War Records Division of the National Archives. Being in good condition and unrestricted, they form basic sources for any study of modern Japanese military history. They are one of the largest bodies of primary Japanese materials on any subject available in the United States and can be expected to shed light also on various phases of Japan's modern social, economic, political, and diplomatic development.
