Buddy reading is a collaborative reading experience where individuals read the same book and discuss it together. This presentation introduces an online buddy reading community that encourages extensive reading among adults in Japan as a form of lifelong learning. Established in July 2023, the group has 27 members, meets monthly via Zoom, and communicates through LINE. So far, they have read five books. The presenters, one organizer and one participant, will share research findings focusing on how the community supports continuous language learning and fosters reading as a more social activity, based on data such as LINE communication records, participation notes, and interview transcripts. In addition, further details will be shared. This community model highlights how digital platforms can bring readers together from diverse backgrounds to share insights, build connections, and support one another’s learning journeys. The presentation will also explore ways to enhance engagement in similar online reading communities.
