Historical Research of Japanese Language Textbooks and Methodology

有一些研究报告是基于第二次世界大战之前印刷的日语教科书（更准确地说，是在1945年战争结束之前）。但是，对于1945年以后出版的教科书，还没有全面的报告。此外，我发现没有任何政府部门保存和管理这些教科书，甚至没有它们存在的记录。因此，我决定研究并寻找保存战后印刷的珍贵教科书副本的地方。我的计划是把这些教科书复制一份作为收藏，同时，为日语教育创建一个自战争以来印刷的材料的文献记录。在这个过程中，我意识到战后的文本仍然与战前印刷的文本具有相同的内容和形式。因此，作为第二次世界大战后日本教科书目录的一部分，我将1935年至2000年出版的日本教科书列入其中。共有1445本书被收录；475本战前教科书，970本战后教科书。从名单上可以看出，50年代的教科书只有16种，60年代的教科书有68种，70年代的教科书有146种，80年代的教科书有244种，90年代的教科书有463种。就日本教科书的发展而言，直到20世纪60年代，日本教科书的增长幅度很小，每年不到10本。然而，在20世纪70年代发生了很大的变化；从每年10份增加到25份，平均每年14.6份。80年代和90年代分别增加到24.4份和46.3份。我希望这份清单能对基础资料档案和今后的日语教育研究有所帮助。

There are some research reports that are based on Japanese language textbooks printed before World War II,(more precisely before the war ended in 1945). However, there has been no overall report made for the textbooks that got printed after 1945. Furthermore, I have found out that there is no government ministry or department that keeps and takes care of the textbooks or even a record of their existence. As a result, I have decided to research and find places that have kept valuable copies of textbooks that were printed after the war. My plan was to make a copy of those textbooks for a collection, and at the same time, create a documentary record of materials that have been printed since the war for Japanese language education. In the process, I have realized that post-war texts still share the same contents and formation as those that were printed pre-war. Therefore, as a part of the List of Japanese textbooks after World War II , I have included Japanese textbooks that were printed from 1935 to 2000. There are 1,445 books listed in total; 475 textbooks from pre-war, 970 textbooks from post-war.From the list, I identified that there were only 16 textbooks printed in 1950s, 68 textbooks in 60s, 146 textbooks in 70s, 244 textbooks in 80s, and 463 textbooks in 90s. In terms of Japanese textbook development, there were only very small increases up to 1960s, less than 10 copies in a year. However, in 1970s there was a big change; there was an increase from 10 copies to 25 copies per year, an average of 14.6 copies. Also, in 80s the average increased to 24.4 copies and in 90s it increased to 46.3 copies.I hope this list will be useful for a basic data file and for Japanese language education research in the future.
