The current study examined the impact of video-based conversational interaction on the longitudinal development (one academic semester) of second language (L2) production by college-level Japanese English-as-a-foreign-language learners. Students in the experimental group engaged in weekly, dyadic conversation exchanges with native speakers in the US via telecommunication tools, wherein the native speaking interlocutors were trained to provide interactional feedback in the form of recasts when the non-native speakers’ utterances hindered successful understanding (i.e., negotiation for comprehensibility). The students in the comparison group received regular foreign language instruction without any interaction with native speakers. The video-coded data showed that the experimental students incidentally worked on improving all linguistic domains of language, thanks to their native speaking interlocutors’ interactional feedback (recasts, negotiation) during the treatment. The pre-/post-test data led to significant gains in their comprehensibility, fluency and lexicogrammar, but not in the accentedness and pronunciation dimensions of their spontaneous production abilities
