In this paper, I paid attention to unsigned teaching materials of first post-war Japanese language official textbook“ Japanese Language Junior High School” for the junior high school, which Omura was involved in editing. I examined it by comparing it with the unsigned teaching materials of the textbook “Junior High School Comprehensive Japanese Language” issued by the educational book involved and the practice records by Omura and the learning records written by learners in the Omura Classroom. In the process of forming Omura’s listening and speaking learning instruction in the early stages of the post-war period, unsigned teaching materials in “Japanese Language Junior High School” envisioned learning instruction that incorporates the listening and speaking learning instruction in the learning instruction of writing in the learning guide. After that it was clarified that in “Comprehensive Japanese Language for Junior High School”, the direction of learning instruction was clearly positioned in the comprehensive unit.
