Military History Documents at NIDS

The National Institute for Defense Studies (NIDS) has collected historical documents related to the Imperial Army and Navy, to conduct research on, and compile Japan’s military history. Most of the documents were destroyed by the military at the surrender of Japan in World War II, and the rest were scattered. The papers that had survived were seized by the Allied Occupation Forces and kept at the U.S. National Archives. After long diplomatic negotiations to take back the documents from the United States, they were finally returned to Japan in April 1958. Most of them are kept at the Military Archival Library of NIDS.
The collection at the NIDS includes the documents returned from the United States along with those kept at the Bureau of Repatriation of the Ministry of Health and Welfare after the war, and others gathered by NIDS itself. The collection consists of 58,000 volumes related to the Imperial Army and 38,000 volumes related to the Imperial Navy.

The following are the principal documents.
