This article aims to evaluate transitional justice carried out in South Korea from the perspective of democratic consolidation. The transitional justice of South Korea encompasses a wide array of historical issues including collaboration and forced mobilization under Japanese colonial rule, massacres before and during the Korean War, as well as the state violence and human rights abuses that occurred under military rule. Twenty-five laws related to the issues have been passed in the National Assembly, and twenty-two separate committees have been set up, in order for those who died, disappeared, were injured or arrested to recognize, restore their honor, and compensate their losses. incidents of human rights abuses under the authoritarian regimes like fake espionage, have been investigated and exposed, and relief measures for victims including retrial and institutional arrangements have been proposed to the government. However, vested interests formed under authoritarian governments continue to resist legislative and policy efforts aimed at transitional justice even after democratization. The responsibility of perpetrators has not been properly inquired, and investigations have been understaffed and lacked the enough time, drawn little attention of the public. There are some important tasks remaining with respect to transitional justice: it is to weaken the power of Cold War liked authoritarian forces, and to bring democratic values to the wider public in South Korea.
