In this study, Omura reviewed the changes in ma’s composition education after the war, and clarified the following three points. (1) Since Omura moved to a new junior high school, the categories that he has consistently focused on until he retires are “(1) ideas,” “(4) descriptions,” and “(5) suggestions.” (2) The period classification of new guidance on essay education in postwar Omura may be divided into the first to fourth periods. (3) The fact that Yasui’s list is “the culmination” is that “the learning material created after aggregating the practices up to Bunkai is what became the last fulfilling learning material of the career”, but in this paper, based on longitudinal research, the term “culmination” was corrected so that it is “the most suitable learning material for the guidance and evaluation of the third term (the late Bunkai).”
