Hiromichi Hosoma is a Professor at Waseda University's Faculty of Letters, Arts and Sciences, where he has been teaching since 2019. Previously, he was affiliated with The University of Shiga Prefecture's School of Human Cultures from 1995 to 2019. He holds a Doctor of Science degree from Kyoto University Graduate School and specializes in the study of human interaction through bodily movements, gestures, and multimodal communication. Professor Hosoma's research focuses on how multiple people coordinate their bodily movements and spatial awareness in various settings including daily conversations, traditional performing arts, and caregiving situations. His work spans cognitive science, social psychology, linguistics, and social welfare, with particular attention to interaction analysis, conversation analysis, gesture studies, onomatopoeia, and elderly care. He investigates how speech and gesture work together to create shared understanding in social contexts, examining phenomena from mundane activities like card games and page-turning to specialized settings like tap dance instruction and dementia care. His scholarly output reveals a consistent focus on multimodal interaction across diverse contexts, with recent work examining latency in telecommunication, weight representation through touch, and deaf-hearing interaction in dance instruction. His publications demonstrate an interdisciplinary approach that bridges cognitive science with practical applications in healthcare and cultural analysis. Professor Hosoma has secured multiple research grants from the Japan Society for the Promotion of Science, including his current project on home care for elderly people with dementia (2025-2028). He is an active member of the Japanese Cognitive Science Society, Qualitative Research in Psychology, and the Japanese Association of the Sociolinguistic Sciences, contributing to both academic discourse and public understanding through book reviews and media commentary on manga, animation, and visual culture.
