Just take your pick: “comfort women,” the Bataan Death March (one of my relatives was killed in this one), Bombing of Singapore, the Parit Song Massacre, the Laha Massacre, the Kalagon Massacre, destruction of mosques and ethnic cleansing of Muslims (Hui, Moro, Suluk, and more), and on and on. The Japanese royal family oversaw most of these atrocities while Tojo took most of the blame.
