Persecution and forced contributions from the Chinese community

Sook Ching

The occupation fell hardest on the Chinese community of Singapore and Malaya. Because many of them had supported China in its war against Japan through fund-raising and boycotts organised by community leaders, the Japanese military regarded the community as hostile. Three days after the surrender, on 18 February 1942, the Japanese began a purge known in Chinese as Sook Ching, “purge through cleansing”. Chinese men between the ages of 18 and 50 were summoned to screening centres. Those whom the military police, the Kempeitai, and their informants identified as anti-Japanese were taken away and shot. At Changi Beach 66 civilians were killed on 20 February 1942, while at Punggol some 300 to 400 civilians were killed on 23 February.¹

The number of victims has never been established. Japan later claimed that no more than about 6,000 people died. Lee Kuan Yew put the figure at about 70,000, a number that included victims in Malaya. Retrospective estimates by historians range from about 25,000 to 50,000 deaths in Singapore itself. An affidavit given after the war by a Japanese officer, Lieutenant-Colonel Hishakari Takafumi, stated that the plan had been to kill 50,000 Chinese.² The divergence between these figures has itself become part of the history, because it reflects the long refusal of the Japanese state to investigate the massacres.

The Overseas Chinese Association

Once the killings had ended, the military administration turned to the economic subordination of the community. It established the Syonan Overseas Chinese Association, which held its first meeting at the Goh Loo Club on 2 March 1942. The elderly physician and reformer Lim Boon Keng became its president.³ The association was presented as the representative of the Chinese community. In practice it transmitted Japanese demands and made the leaders of the community responsible for meeting them.

The leaders who served in the association did so under duress. Many had seen friends and relatives taken away during the screenings, while some had been detained themselves. The Japanese official Mamoru Shinozaki later claimed to have protected Chinese and Eurasian residents by issuing thousands of “Good Citizen” passes, although his role remains disputed.⁴ The ambiguity of collaboration under occupation would shape the post-war politics of the Chinese community and the careers of several of its leaders.

The fifty million dollar “gift”

The most direct financial consequence for the community was a demand for a “gift” of $50 million, which the Japanese military administration imposed on the Chinese of Malaya through the Overseas Chinese Association. The original deadline was 20 April 1942. It was extended first to 20 May and then to 25 June. The association organised the collection as a levy on wealth. Dialect groups were assigned to assess each other’s assets. Those who owned assets worth more than $3,000 were taxed at 8 per cent.⁵

The full amount could not be raised in time. On 23 June 1942 eleven Singapore businessmen, led by Lim Boon Keng, signed a document of lien in favour of the Yokohama Specie Bank. According to the National Heritage Board, the Chinese leaders had raised $28 million and were forced to borrow the remainder. The loan carried interest at 6 per cent a year and had to be repaid within one year. On 25 June 1942 Lim Boon Keng presented the sum to General Yamashita.⁶

The transaction combined extortion with the forms of finance, since a Japanese bank lent to the victims the money that they were forced to pay to the Japanese army, at interest and against a lien signed by the leaders of the community. The lien made the leaders personally exposed for a debt that served no purpose of theirs. One of them, the banker Tan Ean Kiam, had stayed in Singapore and was drawn into the association to manage Chinese affairs with the Japanese. He died in March 1943, less than a year after the presentation.⁷ For the history of the financial centre, the episode is a reminder that the wealth of a community can be held hostage to the security of its members. The “gift” was a ransom paid by a community whose men had been killed in the preceding weeks.

Property, savings and the wider damage

The forced contribution was only one channel through which the community lost its wealth. Rationing, requisitioning and the monopoly purchase of commodities transferred goods to the Japanese at prices fixed in a depreciating currency. Food imports and exports passed to Japanese companies, while local wholesalers and retailers needed military approval to continue trading. Savings held in banks or in cash lost their value with the currency. Those who held savings in the Japanese-sponsored post office savings bank saw their balances inflated away, while about $3 million was withdrawn from the British Post Office Savings Bank during the occupation.⁸

The Japanese also moved part of the Chinese population out of the city to grow food. The Overseas Chinese Association helped to resettle Chinese families to Endau in Johor for the New Syonan Model Farm.⁹ The schemes gave the authorities a means of relieving the food shortage. For the settlers they meant the loss of urban livelihoods and the exchange of commercial skills for subsistence farming.
