Japan is experiencing a growing influx of international migrants. These individuals establish new social connections in both their private and professional lives, which often involves learning Japanese. However, Japanese is just one resource within a broader, multilingual repertoire. This presentation explores the lived experiences of multilingual individuals in Japan, focusing on two spheres that typically require distinct sets of communicative competences: romantic relationships and workplaces. Drawing on data from narrative interviews, our speaker will demonstrate how multilinguals rationalize their interactional partners’ behavior and attribute intentional states to them to make sense of their experiences and their implications for perceptions of language competence. He will argue that competence should be understood as an intersubjective capability that emerges in interactions between individuals, across time and spaces, and institutional contexts, all while being intertwined with emotional expressions.
