Information on supply organization and procedures was compiled from interrogation of the cx-officors of the various bureaus, departments, and units concerned. Official records of the .army and Navy were destroyed in August 1945 on the direction of Imperial Headquarters. Consequently data on the actual distribution of supplies during the uar were similarly gained from interrogation of the cx officcrs v:ho had been directly associated uith the execution of these responsibilities, private records, though in most cases fragmentary, in the hands of these individuals, or estimates compiled by them, proferrcd in substantiation or expatiation of declared supply policies and procedures, were, in lieu of official documents, accepted upon satisfactory establishment of their credibility, and, where considered significant, incorporated in this volume. Intelligence gathered by investigators who prepared other volumes of this report was resorted to as a correlation-bases in the process of counter-checking infor mation submitted, and forestalling deliberate falsification or attempts at misleading reservation. Zv~ry possible check having been made to insure their accuracy, the information delineated and con clusions derived therefrom, it is believed, .are essentially correct. No separate chemical warfare service existed -with the Japanese i^rmed Forces. In the Army responsibility for storage and distribution of general chemical warfare supplies uas divided among four services- ordnance, intendance, medical, and veterinary—each of which maintained its own depots. Air depots stored principal stocks of chemic:..l bombs. Navy supplies v;.rc stored in the naval store departments and aeronaut ical depots of the naval stations* Japanese inventories of significant stocks of chomical warfare materiel in these installations were, in most cases, verified by Unit Chemical Officers or C b Technical Intell igence Teams, and are tabulated in this volumej the Ir.clz of definite confirmation, in the case of a few installations, is attributed to the difficulties experienced by investigating personnel in positive ident ification of some items, end to the fact that the arrival of qualified C'7S personnel at some of the less accessible targets found destruction of materiel already executed without accurate identification. The wide dispersal of stocks throughout scattered warehouses, public build ings, caves, tunnels, and open areas was cited by many investigators as having made specific designation of the targets themselves,- in so:JO instances, an uncertain process. In this connection, even the Japanese depot personnel were often vague, maintaining that comparatively little -IV attention hid be^ii paid to chemical v/arfaro supplies during the latter part of the ;,ar, and that lacking the records \;hich had been destroyed, they v:orc forced to locate stocks haphazardly.. Lack of definitely prescribed methods of storage in all but i few installations v;as emphasized in reports of target investi gation; this v;as largely due to the apparently frantic decentral ization of stocks that took place with the intensification of air raids during the v/ar. Although significant stocks of Air Force chemical warfare supplies arc tabulated in this volume, the investigation of Air Force depots and supply procedures is detailed in separate reports by Chemical Section ATIG-, Adv.. Ech., F-JAF on file in Air Documents Division, T-2, "Tright Field, Dayton, Ohio.

(Figure. 1). 2, The Ministry of War, (Rikugun oho), its chief directly responsible to the Emperor, was the administrative and supply agency of the Army. The Minister of War controlled the procurement and supply of all military equip ment, carrying out his functions with the assistance of Staff and Operation al Bureaus.
