Editor’s Notes:

I recently discovered my local university library has the entire collection of Japanese Monographs on 14 reels of microfilm. It appears to be the revised and edited version of the original Japanese Monographs as some of the documents is dated 1962. HyperWar already has a significant collection available but there are several of the monographs missing in PDF format or unavaliable at all. HyperWar organizes the monographs of theatre/topic and includes a brief description of each of them. I hope to fill in the gaps by digitalizing the missing monographs so that this valuable resource is fully avaliable on the internet.

For now this page will contain the monographs missing from the HyperWar website and will be expanded in the future to contain all 185 monographs. If you cannot find the one you are looking for and it is unavailable on both websites it will hopefully be scanned in the near future.

For pages that were unforunately unclear due to their originals being of poor quality as well as for large diagrams/pictures, multiple scans were taken at various brightness and contrast to ensure as much details were scanned properly. If there are any errors in the documents or specific sections you need a closer detailed scan please feel to use the contact page; I will try to help with any requests!

Also for those with limited bandwidth, note the number of pages on the link! Some of these files are quite large such as No 69 which is 125 pages at 78 MB!

Update History:

January 27, 2019 – Added Missing Monographs from Reel 6 [No. 69 to 83]

February 4, 2019 – Added Missing Monographs from Reel 1 [No. 1 to 5]

July 8, 2019 – Added No 7, 8, 9 and 114.

November 23, 2019 – Added No 165, 167, 168, 175, 176, 177, included HyperWar links for reference and completed list of monographs (makes it easier for me to figure out which one isn’t digitalized yet)

PREFACE

Through Instruction No. 126 to Japanese Government, 12 Oct 45, entitled “Institution for War Records Investigation”, steps were initiated to exploit military historical records and official reports of the Japanese War Ministry and the Japanese General Staff. * Upon the dissolution of the War Ministry and the General Staff, and the transfer of their former functions to the De-mobilization Bureau, the general research job continued and resulted in the development of a series of historical monographs. Detailed instructions covering the preparation of these monographs were included in Memoranda 15 December 1945 and 21 November 1946, subject “Japanese Operational Histories”.

The basic material contained in this operational record was developed by former officers, on duty in command and staff units within major units during the period of operations. It should be noted at once, that the enormous destruction by aerial bombardment and fire has practically wiped out the Tokyo records; much of this material was reconstructed from memory.

The paucity of original orders, plans and unit journals, which are normally essential in the preparation of this type of record, most of which were lost or destroyed during field operations or bombing raids rendered the task of compilation most difficult; particularly distressing has been the complete lack of official strength reports, normal in AG or G-3 records. However, while many of the important orders, plans and estimates have been reconstructed from memory and therefore are not textually identical with the originals, they are believed to be generally accurate and reliable. Further data as a result of continuing research and occasional recovery of hitherto unavailable original documents will be covered in a subsequent publication of “supplements” by the Demobilization Bureau.

*The action under this memorandum and incidental detailed instructions, which followed, were initiated by the Assistant Chief of Staff, G-2, GHQ, charged with responsibility for execution of the program under G.O. No. 9, SCAP, 2 October 1945.

In order to protect the interest of the United States, in exploitation of Japanese Military Information, sub-paragraph 4 of G.O. No. 9 further provided for the screening of enemy documents and established inventories in Japanese Governmental Archives. Careful examination of the first records submitted by the Japanese Government in the summer of 1946 detected a misconception on the part of the Japanese as to what should be included in comparative histories; in a memorandum issued by Assistant Chief of Staff, G-2, on 21 November 1946, the Imperial Japanese Government was directed to record the operations of the Japanese forces more extensively. The G-2 Section thereafter assumed coordination of the entire program, including the establishment of a small historical research section with the ATIS (Allied Translator and Interpreter Section.)
