ARTICLE INFOMany Japanese language learning modules have been prepared or developed independently by each department or study program. To get a new Japanese learning experience, students need learning media that present interesting and up-to-date, which can be accessed online anytime, anywhere. Interactive online modules are one of the media that can make this happen. Students can download and access the online module as an ebook via their PCs, laptops, or devices. The online module materials have links directly connected to explanation videos related to basic Japanese. In each chapter of the material, there are also interactive quizzes that can test students' insights. The method used in this research is Reeves' DBR (Design-Based Research) model, which consists of four phases. Phase 1 is in the form of identifying material, media, and module needs through interviews. Phase 2 is creating and preparing online modules following the syllabus for the basic Japanese course material. Furthermore, in phase 3, the module was tested twice on students who chose the basic Japanese courses. In phase 4, the trial data will be analyzed, and then it will be explained whether the online module that has been developed can be used in learning Basic Japanese. The results of the questionnaire in the trial showed that all aspects of the assessment received good responses and were included in the "high" category so that the module could be used in online elementary-level Japanese learning. Even so, it still needs several revisions and refinements related to evaluation questions and the content of the module's material before it can be implemented in learning in the following years.
