Sook Ching participant Empire of Japan
Aftermath
Trial
In 1947, after the Japanese surrender, British authorities in Singapore held a war crimes trial for the perpetrators of the Sook Ching. Seven Japanese officers: Takuma Nishimura, Saburo Kawamura, Masayuki Oishi, Yoshitaka Yokata, Tomotatsu Jo, Satoru Onishi, and Haruji Hisamatsu, were charged with conducting the massacre. Staff officer Masanobu Tsuji was the mastermind behind the massacre, and personally planned and carried it out, but at the time of the war crimes trials he had not been arrested. As soon as the war ended, Tsuji escaped from Thailand to China. The accused seven persons who followed Tsuji's commands were on trial.During the trial, one major problem was that the Japanese commanders did not pass down any formal written orders for the massacre. Documentation of the screening process or disposal procedures had also been destroyed. Besides, the Japanese military headquarters' order for the speedy execution of the operation, combined with ambiguous instructions from the commanders, led to suspicions being cast on the accused, and it became difficult to accurately establish their culpability.
