This study clarified what young people were learning at a “discipline dojo” in Okutama, Ichinoseki, Iwate Prefecture and clarified the contents of a lecture book used at the dojo in 1956. Furthermore, those contents were compared with those of a lecture book used at the dojo in 1973, 17 years later. Findings indicate that the dojo was a place to learn about local traditions and culture by learning about a wedding ceremony. From the lecture book used in 1955, the author gained detailed knowledge about ceremonies such as handing over a large chest of drawers, “nagamochi,” and about the “uchi-ita” and “kozairi-shiki” ceremonies. Polite Japanese expressions such as “gozaimasu” and “moushiagemasu” were used frequently in vocal messages presented in the lecture books. Also, an emcee known as “torimochi” began the ceremony with a guided meditation. A change in society was apparent from the reduction and simplification of the dojo contents which had occurred during those 17 years.
