We convey or receive information by non-verbal behavior in conversation, too. This means there is each of the language system even in non-verbal behavior. Therefore, in this study, I would like to investigate and analyze nods in the conversation of Japanese native speakers and Korean native speakers and clarify the characteristics of each of nods. As a result, in addition to the differences in the number and function of nod, Japanese native speakers often nod consecutively. On the other hand Korean native speakers often nod with language behavior. It is caused by the difference in the style that Japanese conversation is a cooperative style, and the Korean conversation is dialogue.
