the Japanese invasion of China. Because Hou had directed and written a number of patriotic Chinese "national defence" films against that invasion, he was targeted by the Japanese immediately after Singapore fell and killed at the beginning of the massacre. 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. Verdict Saburo Kawamura and Masayuki Oishi received the death penalty while the other five received life sentences, though Takuma Nishimura was later executed in 1951 following conviction by an Australian military court for his role in the Parit Sulong Massacre. The court accepted the defence statement of "just following orders" by those put on trial. The condemned were hanged on 26 June 1947. The British authorities allowed only six members of the victims' families to witness the executions of Kawamura and Oishi, despite calls for the hangings to be made public. The mastermind behind the massacre, Masanobu Tsuji, escaped. Tsuji, later after the trial and the execution, appeared in Japan and became a politician there. Tsuji evaded trial, but later disappeared, presumedly killed in Laos in 1961. Tomoyuki Yamashita, the general from whose headquarters the order seems to have been issued, was put on another trial in the Philippines and executed in 1946. Other staff officers, who planned the massacre, were Shigeharu Asaeda and Sōsaku Suzuki. But, as Shigeharu was captured in Russia after the war, and Suzuki killed in action in 1945 before the end of
