A Synthetic Research on Sen' yukai

战后日本的退伍军人志愿者协会被称为参友会，据说人数最多时超过5000人。按照最初的研究计划，我们对一些仙友会的成员进行了大量的采访。此外，我们还收集了各个千友会发表的各种文件，这些文件都传达了详细的信息。2012年，我们出版了千友会研究笔记（“千友会研究诺托”，东京清久沙），其中我们一方面整合了访谈和文件研究的结果，另一方面整合了2005年进行的调查研究的结果。这本书几乎涵盖了所有关于仙友会的问题，其中之一是为什么独特的自愿协会只存在于战后的日本。我们的结论是，仙友会的存在本身就是对战后日本整体的严厉批判。

Veteran's voluntary association in postwar Japan is called sen' yukai, the number of which was said to amount to more than 5, 000 at the highest. Following the original research plan, we had lots of interviews with the persons belonging to some of those sen' yukai associations. Also we collected varieties of documents published by each sen' yukai, which convey the detailed information with it. In 2012 we published Research Notes on Sen' yukai("Sen' yukai Kenkyu Noto", Seikyusha, Tokyo), where we integrated the results of interviews and those of document study on the one hand, and the results of the survey research conducted in 2005 on the other. The book covers almost all the questions concerning sen' yukai, among which is why the unique voluntary association exists only in postwar Japan. Our conclusion is that the existence of sen' yukai is itself a severe criticism of postwar Japan as a whole.
