In Japanese conversations, it is often observed that speech styles shift from polite to plain and vice versa as seen by a speaker's utterances. A considerable amount of research has been conducted on style shift in Japanese. Many of the previous studies claim that style shift has two functions: (a) to control the psychological distance with interlocutor and (b) to act as a boundary marker of discourse. However, no speculation has taken place concerning the kind of situations where the shift to plain-style tends to occur and its occurring ratio. This study, based on eight conversations lasting approximately 200 minutes between  Japanese native speakers from the same generation in their initial encounter, examines the situations where the shift to plain-style occurs. The eight conversations are essentially in polite style, but 450 of the total 3,467 utterances shift to plain style. Analysis of the contexts where these 450 plain-style utterances occur indicates that there are at least eight situations where the shift to plain-style tends to occur. The eight situations can be classified into three types relating to: (1) reception of information, (2) arrangement and organization of information, and (3) expressing emotion. It is also indicated that the shift to plain-style seen in native Japanese speakers is performed subconsciously, but native Japanese speakers are aware that these eight situations present an opportunity whereby they can shift to the plain style in order to show intimacy towards the interlocutor and create a relaxed atmosphere., application/pdf},
