Since the beginning of 2020 following the spread of the COVID-19 epidemic, ODL has become the new norm in education either at the primary school level or in higher education institutions. This study is motivated to identify the student's perception of the teaching and learning platform chosen by the instructor so that the ODL session can be optimized and will successfully assist the students' attainment of the Japanese language course. The purpose of this study is to investigate how students perceive Telegram as an ODL platform for learning Japanese. This quantitative study used a 5-point Likert scale as an instrument. The survey was divided into five sections. Section A was the demographic profile, Section B was Learner-to-Learner Interaction, Section C was Learner-to-Instructor Interaction, Section D was Learnerto-Content Interaction and Section E was Learner-to-Platform Interaction. There are 26 items for the Four Types of Interactions. 186 students learning Introductory Japanese Level II participated in this survey. Data is analyzed using SPSS Frequency Statistics, Descriptive Statistics and Paired Samples T-Test. The findings of the study show that students agree with the choice of Telegram as an online Japanese learning platform and the interaction between students, instructors, content and platform is positive. It is suggested that qualitative studies are also conducted to explore more about their perceptions of Telegram being a platform for ODL.
