Since 1991, scholars across Asia have dedicated themselves to reconstructing the history of the Japanese military's "comfort women," analyzing documentary records and interviewing survivors to reconstruct the facts related to this system of sexual slavery. As a result, the international community has gradually reached a consensus that this system was a war atrocity involving massive human rights violations, for which Japan should apologize. However, within Japan, many still deny responsibility for the invasion of China and its related atrocities. Therefore, we should spare no effort to remember this history and ensure it is remembered by future generations, for example, by discussing this sexual slavery atrocity in school textbooks, applying for UNESCO's Memory of the World Register, producing documentaries, or establishing museums and memorials. Other Asian countries continue to engage in heated debates with Japan regarding the nature and scale of the comfort women system and the appropriate terminology to describe it.
