This discourse-analytical case study focuses on clarification requests in experimental social talk in ELF situations between unacquainted Japanese and Indian participants. Numerous types of clarification requests exist. Among them, a sequence of body movements employed by Japanese participants during the conversation was selected for the analysis. With the sequence of body movements, Japanese participants implied that they realized their lack of understanding. The Japanese tended to consider meaning by themselves without uttering clarification questions to the speaker. Indian participants showed that they were perplexed by the Japanese participants’ behavior, especially their body movements. It was found that clarification requests from Japanese participants did not work very well in conveying the message. It is assumed that their priority is set on politeness in social interactions.
