In this study I researched the changing process of 'Chosun Educational Statute' of Japanese imperialism as a means for colonizing Korea, and during that time education of KRJ How was Japanese educational policy to KRJ proceeed, was the activities of ethnic consciousness education of KRJ promoted. During the 36 years since Japanese deprivation of Koreans' national rights in 1910, the Japanese colonial educational policy was consistent with 'Hyangkuksinminhya Education' (Japanese royal subjects who were faithful to its Emperor) or 'Assimilation Education' to make Koreans Japanized. 'Chosun Educational Statues' had changed four times. For Japanizing KRJ quickly, Japan drove 'Separation Education' and 'Isolation Education' as a means of a transitional period of active 'Assimilation Education', and enforced discrimination and assimilation with 'Concord Education'. But KRJ kept their traditional culture and set up night-schools and ethnic consciousness classes all over Japan and taught their children Korean language and the Korean history for inspiring the spirits of independence.
