Abstract
The purpose of this research is to investigate the changes in exchange students’ social networks and Japanese language use over the course of studying abroad. Two exchange students participated in the study. Their social network data and interview data were gathered along with OPI and SPOT test results. Among two students, one showed a development of friends’ network in Japan, while the other did not show such development and kept communication with friends from his home country. The results indicated that two students’ social networks influenced who and how often they used Japanese outside the classroom.
