The Sook Ching massacre began on the 18th of February 1942, three days after British and Commonwealth forces surrendered to Japan. The operation targeted ethnic Chinese males aged 18 to 50 who were suspected of being anti-Japanese.
Historians estimate that between 25,000 and 50,000 people died during the Sook Ching operation in Singapore alone. While Japan claimed no more than 6,000 deaths occurred, Prime Minister Lee Kuan Yew stated verifiable numbers reached about 70,000 including figures in Malaya.
Masayuki Oishi commanded No. 2 Field Kenpeitai from headquarters at the YMCA Building on Stamford Road. Masanobu Tsuji served as the mastermind behind the entire massacre but escaped justice by fleeing to China immediately after the war ended.
Executions occurred at multiple sites including Changi Beach, Punggol Point, Tanah Merah Beach, and Katong trenches. Victims were packed into trucks near screening centres and transported to these killing sites where they were shot or buried.
