This paper discusses group activities in Japanese Anime Research class. A large number of Japanese learners are partial to Japanese pop culture. In Anime research class, we tried to analyze anime and participated in group presentations. The purpose of this work was to develop each student's speaking ability and gain experience in presentation. I analyzed the results of surveys from the view point of peer learning. Students considered the group work favorable. During group activities the presence of a listener made them use more effort in effective presentation. The respectful relationship between listener and speaker influenced the speaker's effectiveness.
