In this paper, we introduce the auditory-based online learning materials, in which elementary level's learners will get used to basic structure of Japanese. Our materials contain the following tasks; for example, to judge whether the sentence is affirmative or negative, to determine whether the actioner in the sentence of offering or asking a favor is a speaker or a listener, etc. Each task consists of 3 steps; 1) to listen to the essential grammatical element which is important to understand the whole meaning of the sentence, 2) to listen to the preceding word of the element above, and 3) dictation practice. Our new development enables learners to learn Japanese, keeping their own paces.
