“There is just one thing that I am certain of about war crimes trials, that is, they are ‘uncertain things’ [futashika na koto],” so Capt. Sumi Toyosaburō wrote as he reminisced over his experience of the British war crimes proceedings at Singapore. He had been a midlevel officer of the Japanese army-navy joint occupation forces on a remote island of Car Nicobar in the Indian Ocean. Formerly British-controlled penal colonies, the Andaman and Nicobar Islands came under Japanese military control during the Pacific War with the view to provide air and naval support in the CBI theater. In March 1946, Sumi and fifteen others were brought to the U.K. Singapore courtroom on charges that in July and August 1945 they arrested, tortured, or otherwise mistreated a number of Nicobarese civilians in connection with spy allegations. The chief accused was Lt. Gen. Itsuki Toshio, formerly commanding officer of the Japanese occupation forces at Car Nicobar. He and two others also stood accused on allegations that they conducted illegal trials and executed eighty-three Nicobar islanders. The Singapore court found all but one guilty. Lt. Col. Saitō Kaizō, Itsuki’s chief of staff, was acquitted while the rest were convicted and received varying sentences: Itsuki was sentenced to death by shooting, five were sentenced to death by hanging, and the remaining nine received different terms of imprisonment ranging between three and fifteen years.
