This paper reviewed studies related to compliments in Japanese with respect to the factors of type, expression, subject, personal relations, response, and utterance sequence. From the viewpoint of Japanese language education, developing subjects of analysis is crucial to ensure that Japanese language learners can maintain and construct interpersonal relationships by using compliments within conversations. By analyzing conversations in their entirety, the workings of compliments in maintaining and constructing interpersonal relationships will become clearer, and the issues that Japanese language learners encounter will be elucidated.
