This article aims to explore the virtuous cycle of transitional justice and oral history archives. Oral history research in Korea has been developed based on the experiences of the socially disadvantaged or social others, which influenced the activities of various truth committees pursuing the truth and reconciliation, but the relationship between the two was not sufficiently reviewed. Based on the case of the Truth and Reconciliation Commission from 2005 to 2010, the results of oral history research are of considerable help in finding the truth, but for further development of oral history research, it is necessary to draw up direct or indirect use of victims' statements or testimonies, paying attention to the Korean War civilian casualties and collective human rights violations. In this context, the concept of 'archival justice' has many implications, and preparations for the establishment of a human rights archive are needed, following the example of the already established 'Democratic Movement Archive'.
