This paper has two purposes. The first is to discover traces of the Hachihonmatsu branch of the Hiroshima Army Weapon Supply Depot (hereinafter referred to as the Depot), which is a war site, by identifying aerial photographs and conducting field surveys. The second is to propose a method for organizing and utilizing information on the war ruins for educational purposes. From aerial photographs we identified 36 facilities that appear to have been used for ammunition or gunpowder storage. Next, through our field surveys, we discovered 13 stone marks indicating the boundary of the land owned by the military around Karimata Pond and some banks surrounding the ammunition storage. This survey revealed the distribution and existence of storage in the Depot. We examined how to utilize each in both school and social education and showed what is required and the significance of utilizing the war remains left over in the area. For education at school, we proposed multi methods including learning about peacetime. Regarding social education, we created a map that promotes a comprehensive understanding of the war ruins for citizens and visitors alike. This article is expected to help promote the reinvestigation and utilization of war ruins that have thus far not been thoroughly investigated.
