The reality of the Middle School Japanese language Textbooks "Chuto-Kokubun" has not been made clear. In my previous paper, I described the compilation in Chuto-Kokubun through the analysis of "Morishita's Diary". In this paper, I will make out two points. as follows: (1) The thought of Chuto-Kokubun is realization of "Mononohu-no-michi" (the code of the samurai). (2) The teaching method of Chuto-Kokubun is repetition of reading aloud.
