It is impossible to obtain absolute historical facts. Although history tends to be thought of as based on facts, data and past events, history by its very nature is subject to human biases, personal interpretations, personal interests, national interests and cultural values. The occurrence of the Nanjing rape continues to be subject to such interpretations. On December 12, 1937, Japanese troops committed an epidemic of mass murder and rape against Nanjing China during the Second Sino-Japanese War. This incident, which became known as the Nanjing Massacre or Rape of Nanjing, lasted six weeks during which the Imperial Japanese Army killed tens of thousands of Chinese civilians and disarmed fighters. Because Japanese military documents about the incident were deliberately destroyed or kept hidden, there is still no accurate estimate of the massacre's death toll. Typical death toll estimates range from 40,000 to 300,000. The incident continues to be a contentious and contentious political issue. Japanese nationalists and historical revisionists claim that the massacre was exaggerated or entirely invented for propaganda purposes. Because of nationalists' efforts to deny or justify war crimes, the debate over the massacre remains an obstacle in Sino-Japanese relations and Japanese interactions with other Asia-Pacific nations. Although the Japanese government admitted to the acts of killing of non-combatants, looting, and other violence committed by the Imperial Japanese Army, as well as veterans serving in Nanjing at the time, admitted to such acts, a vocal and passionate minority within of the Japanese government and society have argued that the death toll... at the heart of the document... and a variety of different views provided on the massacre. Everyone must understand the reality and horrors of war crimes to reduce the possibility of this happening again. Yet, instead of understanding and learning from the past crimes and mistakes of the Nanjing Rape, Japan hides, or worse, denies, the truth. This creates friction and hostility in Sino-Japanese relations. This influences the entire world's perception of Japan. This also prevents younger generations in Japan from fully understanding their country's contribution to World War II, thus allowing the possibility of similar colossal mistakes being repeated. History in general must be interrogated, understood and presented from different perspectives. The truth must come from impartial information; only then can the study of history be effective and reliable.
