The present paper aims to study the process in which the sports days in Taiwan primary schools became a sports ceremony on the initial stage of Japanese colonial period (1895~1911). Starting with the first sports day in Taiwan primary school, this study considers sports days as a kind of ceremony, a faith center of the colony, by investigating the changed locations of sports days. In conclusion, the sports days, originally a product of western civilization, were introduced to Taiwan because of Japanese colonization. Initially, sports days were not held on school campus, and the embryo form of them was "on foot trip." Later, the locations were moved to the school neighborhood or the campus. At the end, the school campus became the local assembly place for holding sports days, and even the education arena for educating Taiwanese under Japanese nationalization. Being different from the Taiwan traditional temple fairs, sports days in Taiwan primary schools combined modern sports with the solemn national ceremony to show the respect for the Japanese Emperor. In sum, Taiwan primary schools provided the space to demonstrate the result of educating and governing Taiwanese body under Japanese rule.
