Study on Letters and Diaries as Personal Media written by Soldiers during the Wars in Modern Japan

本研究以战时士兵的书信和日记作为个人媒介。我们在厘清资料来源的同时，考虑到士兵书信的内容、制度史，以及书信、日记作者对战争的意识和外在认知，进行了田野调查，收集了资料和照片，并进行了分析。此外，我们向公众开放了研究结果，并与全国各地的研究机构建立了合作关系。在这项研究中，我们了解到，参与保存这些历史资料的个人和机构一直在努力完成重印和出版日记的任务。基于此，我们发现这些信件和期刊仍然对许多人产生了影响，并认识到我们必须尝试对内容进行更深入的分析。

In this study, the letters and diaries of soldiers in wartime are taken as personal media. While clarifying where the materials were located, we considered the content and the institutional history of the soldier's letters, and the consciousness and external perception of the war among the people who had written the letters and diaries.For that purpose, we conducted fieldwork, and gathered materials and photographs, which we then tried to analyze. In addition, we opened the results of the study to the public and formed cooperative relationships with research organizations in various parts of the country. In the study, we grasped that individuals and institutions involved in the preservation of these historical materials were continually grappling with the tasks of reprinting and publishing of the diaries. Based on this, we find that these letters and journals still have an impact on many people, and recognized that we must attempt a deeper analysis of the contents.
