Dr. Jotaro Kato


KATO Jotaro is a Lecturer at Department of English, School of Letters, Mukogawa Women’s University.
After working in an NGO to support unauthorized migrants as a caseworker, he completed his PhD at Waseda University in September 2020.
He majors in migration studies, international labor mobility and global sociology. His research interest is on unauthorized migrants and migration infrastructure between Japan and Vietnam. He uses qualitative methods, with the belief that grassroots level observations, participation, interaction, and interviews contain as well as reveal the workings of greater thematic issues. He currently researches on the impact of COVID-19 to Vietnamese (ex-)technical interns. He also considers starting a new research project on old and new Vietnamese migrants’ community in Hyogo Prefecture.
