Abstract
Using the BTSJ corpus, the study examines the frequency of interruptions by Japanese learners in conversation as well as transition of speakers which may take place after each interruption has occurred. As a result, in the cases of conversation at first-time meetings by people of equal relationship occurrences of interrupts is less frequent than in the case of known people. In addition, in the case of friend’s conversations, there was a tendency to liven up the conversation caused by the high rate of transition between the speaker and the turn-taking after the interruptions occurred.
