Bridging Cultures: A Japanese Student’s Path to Intercultural Communication

While Japanese universities promote English proficiency and intercultural competence, admissions still rely heavily on the standardised TOEIC test, often prioritising linguistic accuracy over cultural understanding. This emphasis can marginalise the experiential and interpersonal aspects of language learning essential for developing intercultural communicative competence (ICC). Although ICC is most effectively developed through a combination of formal instruction and informal learning, particularly involving authentic intercultural interactions, there remains a paucity of research examining how learners develop ICC beyond the classroom. Addressing this gap, the present study investigates how Japanese university students’ language repertoires, intercultural experiences, and knowledge shape their studies, and how their ICC develops throughout undergraduate education. One English major student was selected for in-depth analysis following his employment in a culturally diverse workplace that fostered meaningful intercultural interactions. His development was examined using four research tools: a survey, a journal, an interview, and TOEIC scores. The survey and test scores revealed growth in communicative assurance and language proficiency, while journal reflections and interviews captured critical incidents—including a shift from indirect to direct speech—that marked cultural adaptation. These findings suggest experiential learning fosters real-time communication, builds learner confidence, and supports transformational ICC development.
