Unit 731 was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that undertook lethal human experimentation during the Second Sino–Japanese War (1937–1945) of World War II. (Wiki). Thousands of horrific medical experiments were carried out on captured men, women and children, including vivisection without anesthetics. All the articles below make for harrowing reading, and yet, like the Holocaust, it is vital that we remember. Not out of a grim fascination with the abject, but as a memorial to the victims. There are no answers to the questions which arise in the soul when looking on darkness. But just as looking at the eyes of the photographed victims of Pol Pot’s genocide is a profound encounter with the victims’ humanity, to remember is also to protest, to say, never again. It is to know a solidarity with those who have suffered. It is to condemn the evil that possesses men to inflict terrible harm on their fellow creatures. Remembrance is prayer.
