A qualitative study conducted in western Japan examined the perceptions of Korean students in Japanese junior high school to identify factors contributing to a consistently low high school advancement rate compared to mainstream Japanese students. Fourteen people were interviewed about their Korean students' experiences in Japan. The findings of this study suggest that factors contributing to the low high school advancement rate among Korean students cluster around three themes: (1) discrimination experienced in society at large and at school, (2) assimilation to become more like the Japanese, and (3) inconsistent cultural and insufficient academic support given by the school and teachers. Findings from this study indicate how the power structure in a social context of schooling influences minority students' learning and also confirmed in part Ogbu and Cummins' theories of how power relations between the subordinated and the dominant affect minority students' schooling experiences and learning.
