This study aims at verifying how each societies and individuals interpret and add meanings to the mass-killings in which the nations in East Asia (such as Japan, China, and South Korea) had involved in the middle of twentieth century. To achieve this, I will focus on Battle of Okinawa, 228 Events of Taiwan, and Jeju April 3rd Events of South Korea as case studies. Each nation-state has applied various restoration plans or relief measures in coping with the deaths from the massacres. However, the ascription of meaning to mass-killing based on those laws and measures, that is to say 'victimization of the dead', has already encountered criticism that it is being incorporated into the nationalism. This study does not stop at criticizing the ascription of meaning to mass-killing simply as a negative nationalism and, by extension, intends to interpret it based on what they had experienced and felt free from the binary system of official and private matters. While investigating how the scars of the negative histories in East Asian societies have been dealt with and then how it have been contributing to the reconciliation and healing of the societies, this study is also a ground work to look for the possibility of new viewson death and lifefor non-experienced generationsand to generate the reconciliation and mutual understanding in East Asian Society of twenty-first century.
