The objective of this study is to evaluate the effectiveness of using flipbook media in Japanese language learning, with a particular focus on the material "Hajimemashite" for grade XI students at MAN Kota Palangka Raya. Research and Development (R&D) method was used to measure the improvement of students' understanding before and after the use of flipbook. The results are clear: the flipbook media is rated as very feasible, with language, material, and media validation tests. It is clear that students' posttest results increased significantly after using the flipbook (p-value < 0.05). The student response questionnaire showed that the flipbook increased the intensity of self-study. Advertisements that appear in the flipbook application do reduce students' learning comfort. This flipbook media is effective in improving students' understanding of Japanese. However, it needs improvement in technical aspects.
