Tokyo Tribunal 2000

After the Second World War, sexual violence committed by the Japanese Imperial Army was hardly prosecuted by the International Military Tribunal for the Far East (The Far East Tribunal) as set-up by the Allied Forces. An exception was the Batavia (Indonesia) Trial where the case of 35 Dutch women who had been victimized in Indonesia, brought their case against 12 Japanese Army officers at the Batavia court. Charges were made on the grounds of having committed war crimes and in defiance of the laws and customs of war, in the Dutch East Indies in 1944. One of the accused was condemned to death and others were sentenced to imprisonment ranging from two to 15 years. That was the only trial in history that gave justice to the comfort women. Today most of the comfort women are still denied of such justice.

Sarah Soh on Batavia trial

"Nonetheless, among the approximately fifty military tribunals convened at various Asian locales between 1945 and 1951, only one tribunal, conducted by the Dutch in Batavia (today's Jakarta), meted out stern punishments (including one execution) to Japanese officers who forced Dutch women into sexual servitude. The Batavia trial thus recognized the "forced prostitution" (to use the Dutch government's terminology) of thirty-five Dutch women as a war crime. However, it ignored similar suffering by a much greater number of native women in Indonesia, not to mention female victims in other Asian countries. What, then, is the meaning of the Batavia trial for the comfort women issue? Obviously, it was the action of a victorious nation-state protecting the human rights and personal security of its nationals in a colonial setting as a matter of national interest. It underscores the common deprivation of human rights of people under colonial rule."
