The main purpose of this study was to investigate the relationship between teacher's resources and group cultures in Japanese classrooms. According to Hargreaves (1972), the resource is the basis of both liking and power, and it is closely linked with the culture of group. In order to examine his theory, 209 elementary school children and 276 junior high school students were administered to measure perceived resources and power of and liking toward their teachers, and group cultures of classrooms. The following results were obtained: (1) There were six kinds of teacher's resources in classroom. They were "consideration", "appearance", "legitimacy", "leadership", ''expertness", and "play". (2) "Consideration" was the most important resource for teachers. (3) Importance of teacher's resource depended on the classroom culture.
