In the contact scene of Japanese learners and native Japanese speakers, a variety of exchange have been
made in order to provide a thorough understanding of each other. Learner must be made to communicate with native speakers in the information and knowledge of Japanese with limited. However, not only the problem of language format on to handle problems with communication in general, "negotiation of meaning" has become necessary to exchange them. Until now, in the "negotiation of meaning" research in Japanese, studies of task-oriented is the main current. Analysis of conversation from natural scene is rarely seen. In this paper, we
focus on the natural conversation of chat by Japanese learners and native Japanese speakers. There are two
research purposes. One is to figure out what kind of adjustment took place in order to solve the communication problems. And the other is to consider how the adjustment behavior of each is functioning in the interaction. We found that problem of "negotiation of meaning" in conversation education of Japanese should be recognized as a collaborative work to be performed for Japanese learners and native Japanese speakers to share information and understanding of the same common, but not only modification of speech.
