The total number of Japanese casualties in the Asia-Pacific War (1937-1945) is estimated to be around 3.1 million, with military fatalities accounting for 2.3 million. In contrast to the popular image in Japan of these war dead as “noble heroes” (eirei) who fought valiantly in service of the nation, however, the realities of war were quite different. Rather than being killed in combat, some sixty percent of soldiers (1.4 million) died away from the battlefield, succumbing to disease and starvation. Others suffered from the military's failure to secure dependable supply lines to provide food and equipment replenishments, resulting in a large number of otherwise preventable deaths. In this article, Professor Yoshida Yutaka focuses on the grim realities of war death as experienced by ordinary soldiers in the Imperial Japanese Army, a topic rarely touched upon by scholars. Combining a social historical approach with rigorous statistical analysis, Yoshida sheds light on the institutional issues and peculiarities of what was once proudly known as the “Emperor's military.”
