Research in language learning indicates that process drama (PD), an educational approach where students and teachers work in and out of role to explore themes and issues, can be well suited to the Japanese higher education (HE) context. Despite the benefits highlighted in the literature, PD remains a niche approach to language teaching and learning, with a limited number of practitioners in Japan. This study seeks to uncover language teachers' experiences of becoming Process Drama Practitioners (PDPs) and using and sharing PD as an English language teaching approach in Japanese HE. Data were collected via in-depth interviews with six experienced PDPs. The findings indicate that prior positive experiences with drama was an encouraging factor of the adoption and self-directed initial use of PD in their teaching practices. Positive student outcomes and feedback were primary motivators for continued use of PD. Experiences of sharing PD led to a perceived need to distinguish PD from theatre-based approaches and establish connections to familiar approaches to language teaching.
