An objective of this study is to clarify the characteristics and distribution of the stone monuments in Saijo, Higashi-Hiroshima City, Hiroshima Prefecture, and discuss their significance for elementary and junior high school social studies teaching materials. Two hundred two monuments were recognized in this area. They were mostly located in temples, shrines, public institutions, roadsides, and irrigation ponds. The purpose of erecting monuments has changed over 150 years from the Meiji era to the present day, which reflects the transition of the history of the local community or local people’s consciousness about their community. All monuments were classified into three levels considering their significance for elementary and junior high school social studies teaching materials: i.e., A. Useful and sufficient information; B. Useful but insufficient information; and C. Others. As a result, we defined 6 monuments as level A, 71 as level B, and 125 as level C. We propose an example of a social studies teaching plan including information about the monuments according to each level. The monuments directly provided information about the history of the local community and the location of historical events; therefore, the teaching plan using information about the monuments has possibility to improve for social studies.
