The purpose of the study is to explore what kind of citizen characters Japanese expected Taiwanese to be and by what kind of citizenship education to complete their colonial goal under Japanese Ruling on Taiwan. It contains three parts of issues in this paper. First of all, introduce the evolution of colonial and educational policies during the period of Japanese Ruling on Taiwan. Secondly, illustrate the contents of citizenship education. Then, in the latest section, more findings and conclusions are mentioned. We discover that the Japanese course “Disciplining the Person” is not very democratic. The Japanese policy was to make Taiwanese people into semi-Japanese-people who were loyal to the Japanese crown without the same rights as the native Japanese. In other words, Taiwanese people were simply their “political instruments.” Through documentary analysis, historical approach, and comparative approach, several conclusions are made from the findings and discussions of this study. According to the conclusions, this study recommends some implications as follows: 1.extol the priority of Taiwan consciousness and reveal the autonomy of education in Taiwan. 2.implement indigenous education and emphasize native place education. 3.realize the equitable opportunities for schooling. 4.respect every culture and every native language.
