This project, funded and coordinated by The Corts Foundation, aimed to translate into English a few volumes of the official Japanese publications of the war history series known as ‘Senshi Sōsho’.

The Senshi Sōsho project focused specifically on the volumes which are relevant to the study of the Japanese attack on and the subsequent occupation of the former Dutch East-Indies in the period of 1941 to 1945. The focus of TCF was not to translate texts about the general operations of Japanese forces, but only to describe the operations in the former Netherlands East Indies which were not translated before. These volumes deals with the Japanese campaign in the Netherlands East Indies in all its aspects (Army, Navy and their air forces).

A significant role in this project was the former Leiden University Office Tokyo (“LUOT”), that employed Japanese translators in Japan for translating and editing, final editing being done in The Netherlands.

To guarantee optimal results TCF worked closely with members of an Advisory Board in both Japan and in the Netherlands. 

Intermezzo: The introduction on the Senshi Sōsho series, by prof. Tobe Ryōichi here after >>

The task of compiling the official account of the Japanese involvement in World War II, the Senshi Sōsho (war history series), began in October 1955 with the opening of the War History Bureau ( the present Military History Department of the “National Institute for Defense Studies” in Tokyo. The bureau was led by Colonel Nishiura Susumu, a senior official in the War Ministry during the war. The 102 volumes of the series – the first of which was published in 1966 and the final one in 1980 – include 37 volumes on the Imperial Headquarters, 34 volumes on army campaigns, 21 volumes on navy campaigns, nine volumes about air services campaigns, and one volume of chronology.

The so-called Japanese Monographs and Studies published in the late nineteen-forties were the first effort by historians (mostly U.S. Army and Navy general staff officers) to record in English the Japanese military history of the war of 1937-45.

The archive material used for these Monographs and Studies was also the foundation for the 102-volume Senshi Sōsho history of the war written during the 1960s and 1970s. The Japanese War History Office in Tokyo was able to add more detailed information, including new data that came from Japanese documents returned to Japan in 1958 by the Allies which contained personal diaries and interviews with senior officers, etc. These Senshi Sōsho volumes and a few additional volumes, compiled later, were only published in Japanese.

The publication of the volumes was made possible by the financial support of not only the Corts Foundation, but also the Isaac Alfred Ailion Foundation, the Suntory Foundation, the Gravin van Bylandt Stichting, the Netherlands Institute of Military History (NIMH), the Samenwerkende Maritieme Fondsen (i.e. Vaderlandsch Fonds ter aanmoediging van ’s-Lands Zeedienst, Directie der Oostersche Handel en Reederijen, and the Vereeniging de Prins Hendrik Stichting).
