Abstract
This study compared the use of "~Nara" in outgoing and reply e-mail. The results showed that there was a difference between native Japanese speakers and non-native Japanese speakers when sending reply e-mail. In the case of outgoing e-mail, non-native Japanese speakers were able to assume the relationship with the other party by themselves, but it is thought that they were not accustomed to sending reply e-mail, and their writing style was different from that of native Japanese speakers. Therefore, it is necessary to provide instruction, not only for sending outgoing e-mail, but also for sending reply e-mail.
