Abstract
This paper reports on a joint lesson between foreign students (joint classes of three faculties) and Japanese students (the Faculty of Law). Along with the concern of both foreign and Japanese students, "Solving Housing Problems" was given as a subject. An activity which deepens the understanding of the position of each other through role-playing was performed. Consequently, a new side of each group's social culture became evident. This became the motivation for promoting study and to understanding each other further.
