This study aimed in analyzing (1) the Japanese language skills of Monarch Bali Dalung students, especially in learning yobikake-outou no hyogen before the Grammar Translation Method (GTM) is applied; (2) the Japanese language skills of Monarch Bali Dalung students, especially learning yobikake-outou no hyougen after the Grammar Translation Method (GTM) is applied and its effect on students; (3) the factors that influence the application of the Grammar Translation Method (GTM) to Monarch Bali Dalung students in learning Japanese, especially learning yobikake-outou no hyougen. This research is experimental research with quantitative and qualitative approaches. The experimental research design used in this study is a quasi-experimental design. The theories used in this research are language learning theory, pragmatic theory, and sociocultural theory. The results showed that the Grammar Translation Method (GTM) method can improve Japanese language learning outcomes for Monarch Bali Dalung DMM students, especially in learning yobikake outou no hyougen. This can be seen from the average value of student learning outcomes that have increased, namely the average value of the initial test in the experimental group was 21.50 and the final test score is 71.10. The standard deviation of the initial test was 11,859 and the final test was 12,339, while in the control group the initial test score was 21.90 and the final test score was 50.70. The standard deviation of the initial test was 11,923 and the final test was 12,522. The hypothesis was tested by using t-test. Based on the effective category obtained according to the average value (mean) of N-Gain, that the GTM method in learning yobikake outou no hyougen was said to be 'quite effective'. The factors that influence the implementation of the Grammar Translation Method (GTM) were external factors and internal factors. External factors were in the form of unattractive applications, while internal factors are student motivation.
