Abstract
The National Archives of Japan facilitates the preservation and use of the Records of the Court-martials of the
former Japanese Army and Navy. Transferred to the National Archives in 2015, most of these records consist of
original copies of the court-martial judgements. As of the end of August 2020, the collection comprises 1,242 items.
This paper attempts to organize information pertaining to these Records to serve as a reference for users. Firstly,
the author explains the history of court-martials that created these records, by tracing back through the changes to
records management regulations in order to gain an overall understanding of the collection. The author then lists
its features. Finally, the author gives a brief reference guide to use the Records.
