Primary education at this time consisted of elementary schools and public schools, with the former mainly for Japanese children, and the latter for Taiwanese children. The most important subject in school was the national language(Japanese) supplemented by classes in moral and physical education, composition, reading, writing, mathematics ,and singing. The primary goal of public school education was to train Taiwanese children into loyal, submissive Japanese citizens, and thus the schools aims to teach the skills needed to develop various resources in Taiwan. In the early years of Japanese rule, if a Taiwanese person graduated from a public school and wished to continue their education on the island, there were only two choices besides missionary schools: national language schools and medical schools, as there was no public secondary education at that time. It was not until 1915 (Year 4 of the Taisho regime) that the first middle school open to Taiwanese people was built, the Taichung Middle School. In 1919 (Year 8 of the Taisho regime), the Office of the Governor-General partially allowed the establishment of several middle schools, girls’ high schools, vocational schools and special schools. After 1922 (Year 11 of the Taisho regime), with the promulgation of the Taiwan Education Decree, more middle schools, girls’ high schools, vocational schools and special schools were opened. In 1928 (Year 3 of the Showa regime), Taihoku Imperial University was established, becoming the highest educational institution in Taiwan. The entire education system in Taiwan was modeled after the education system in Japan, and the classes taught in the former were interchangeable with those in the latter.
