Each is often applied to improve Japanese pronunciation. The fourmethods include Verbo Tonal, Audio Lingual, Shadowing, and Minimal Pair. This study aims to determine the effectiveness of using the VASMmodelin mastering Japanese pronunciation. The sample in this study was 17studentsof the Department of Japanese Language Education, Universitas Muhammadiyah Yogyakarta. This study used a quasi-experimental method in which the sample was given seven treatments. The data collection technique uses a discourse reading test in which there are Japanese pronunciation sounds that the researcher wants to examine. The tests helped to determine the change that occurred before and after treatment using the VASMmodel.
