This study is to investigate Taiwanese children’s resistances of colonial rule in elementary schools during the Japanese Colonial Period in Chiayi Area. This study adopts the oral history of nine graduates from elementary schools during the Japanese colonial period as the primary source datum, taking oral history series for references. Furthermore, the qualitative analysis software, “ATLAS.ti 5.0,” is used for coding, and management of datum. This study has discovered that there are three ways in which Taiwanese elementary school children resisted Japanese colonists: First of all, they covertly opposed while they appeared to agree. That includes “saying one thing while meaning another” (such as “playing pranks” and “being trouble-makers”) and resisting substitutes. Secondly, they had actions, such as “bullying Japanese children” and “bullying Japanese teacher,” to resist Japanese. Thirdly, those rebellious actions showed the Taiwanese children’s self-reflections on their own national identity. The resistances of Taiwanese children in Chiayi Area against the Japanese colonialism did not include “studying hard” which is common in the existing data, autobiographies and other oral history references. Their resistant styles are more multidimensional and interesting.
