This presentation introduced the ELFJ-Corpus, a digitally curated collection of authentic interactions between Japanese university students and international speakers from diverse linguistic backgrounds, and explored its use in technology-enhanced, culturally situated language education. Drawing on English as a Lingua Franca (ELF) research, the presentation demonstrated how corpus-based learning activities helped students develop awareness of meaning negotiation, strategic communication, and intercultural interaction while engaging with familiar and culturally relevant topics. Examples of student responses illustrated how the corpus supported the development of ELF awareness, intercultural sensitivity, and confidence in expressing local cultural perspectives within global communicative contexts. The presentation also discussed interdisciplinary applications of the corpus and outlined future plans for international collaboration and the integration of additional digital tools to further enhance language learning and research.
