As an attempt to establish an effective way of using natural conversation in Japanese language pedagogy, this study investigates which aspects of interaction learners notice when they see a video of natural conversation between native speakers of Japanese. As the result of classifying instances of noticing obtained from 24 participants who paid attention to grammar in the video, noticing of structural aspects was lowest at the beginner level, with advanced beginners noticing the most. Additionally, few of the beginners noticed pragmatic aspects, and intermediate and advanced learners noticed more in terms of the amount and types. The causes of the above results are discussed, and appropriate ways of showing natural conversation to learners are considered.
