Tandem language exchange consists of a partnership between two learners studying each other’s language. Among the mutual advantages it provides is the opportunity to improve their linguistic and communicative competence and cultural knowledge. Based on reciprocity and autonomy, a self-access center (SAC) may be seen as one of the most suitable places to run this face-to-face exchange program. This ethnographical study collected perspectives from different actors involved in an established tandem program - organisational team and learners - in a SAC, at a Japanese university, through interviews. Findings allowed to gain insights into the program and further understanding of the practices, including benefits and suggestions for improvement. While parallels could be made, findings also showed several differences between the institutions’ initial intentions and the reality of practice. This research may provide other educational settings with ideas to encourage collaboration in outside-of-class exchanges to expand learners' linguistics, communicative, and cultural knowledge.
