Despite the ubiquity of technology and the expanding role of CALL in language education, studies investigating the development of CALL at the national level remain scarce (Fathali & Emadi, 2022). Accordingly, this presentation reports on a methodological review that addresses this gap in the literature by systematically reviewing CALL research conducted in Japan. The study aimed to understand the trends and methodological characteristics (e.g., research designs, research topics, settings) related to the Japanese CALL context. Five leading CALL journals (CALICO Journal, Computer Assisted Language Learning, Language Learning & Technology, ReCALL, The JALT CALL Journal) were searched for relevant research published over a 10-year period (2015-2024). A total of 67 articles were selected according to the inclusion criteria. While analysis of the data is ongoing, the initial findings suggest that Japan-based CALL research has tended to favor quantitative or mixed-method designs over purely qualitative studies. Research on the university context also appears to be dominant. The full research findings and future directions for CALL in Japan will be discussed during the presentation.
