Psychological studies on adjustment of international students in Japan has become increasingly important in recent years because of the abrupt inflow of students from abroad. The results of existing research in this area, however, are not consistent over studies. One reason for this inconsistency is sampling bias due to limited subject numbers and under representation. A second reason is the wide variety of instruments used to measure the concept of cross-cultural adjustment, which has been defined differently by the investigators concerned. This study approaches adjustment through various scales, attempting to grasp as many factors as possible that may underlie the concept, and by attaining a sample that is as close to the characteristics of the international student population in Japan. This report deals with some descriptive statistics and results of factor analysis done on the adjustment scales.
