The twentieth century, which has just come to a close, was a century of war and violence. The Second World War brought to humankind destruction and genocide on an unprecedented scale in which vast numbers of women were made victims of sexual violence. Now we are all witnesses to wars between nations and internal armed conflicts that are breaking out one after another throughout the world. Japan’s military sexual slavery (the “comfort women” system) before and during the Second World War was one of the most horrendous forms of wartime sexual violence against women known in this century.
