The present paper aims 1) to construct an objective feminism scale which measures the level of awareness of sexual equality and the independence of Japanese women and 2) to test the reliability and validity of this scale. A survey was conducted of 174 women between the ages of 20 and 59. The questionnaire consisted of 2 parts: 1) a feminism scale and 2) demographic and psychographic variables. The responses to the scale were statistically analyzed using GP analysis, factor analysis and coefficient reliability. The results show that the scale is reliable as a measurement of feminist awareness as I have defined it. The subjects were (1) divided into three groups (high, medium, low) on their level of awareness and (2) classified into groups for each variable. The fact that significant quantitative differences were found among the 3 groups based on various demographic and psychographic characteristics (e.g. age, education, marital status, work/plans and role consciousness) indicates the validity of the scale.
