In basic Japanese classes as a second language, input is usually the main focus because input is easier to control than output due to limitations such as the number of class hours and the large number of students. As a result, the development of oral and production skills tended to be slower than comprehension skills. As integrated activity from the beginning level are also becoming more and more important, integrated activity is a possible solution to this problem. Therefore, in this study, the author devised a syllabus that incorporates an integrated activity (production of a reading play) for learners of basic Japanese so that they can develop their oral and productive skills. From the results of this study, it was found that the basic Japanese class with integrated activity was effective in fostering not only Japanese language skills but also basic oral and productive skills, improving motivation, and promoting teamwork. Although there is room for further study in terms of implementation and support, it can be said that we have obtained some initial results that will enable us to design classes for non-Japanese majors that incorporate integrated activity.
