Sign language interpreting plays a crucial role in ensuring effective communication between Deaf and hearing individuals, particularly in highly specialized settings such as court hearings and psychotherapy sessions. However, interpreting in these fields presents unique challenges, as it requires not only linguistic skills but also the ability to navigate cultural nuances, emotional contexts, and diverse communication needs. This research project examines the practices of Deaf and hearing sign language interpreters in Japan, focusing on how they handle demands, interpret nuances, and adapt their interpreting strategies to individual Deaf sign language users. Key areas of investigation include the strategies employed by interpreters in the courtroom, psychotherapy sessions, conferences, and media, and how these strategies vary according to context and audience, as well as their adaptation to the linguistically and culturally diverse needs of Deaf sign language users. This presentation will outline the research project and offer a critical overview of the research methodology employed in the study. Details and registration here
