Introduction
Shortly after the British forces surrendered in Singapore on 15 February
1942, the Japanese military began an operation, called Kakyo Shukusei
or Dai Kensho in Japanese and known in Chinese community of
Singapore as the Sook Ching (Purge through Purification), in which
many local Chinese were massacred.
[1] Although the killings have been investigated extensively by scholars in
Malaysia and Singapore , the sources available to them are limited, and
Japanese documents have not been fully utilized in such research. One
purpose of this chapter is to consider what Japanese sources can
contribute to an understanding of what took place.
The first point to be considered is why the massacre took place, and the
second is how the massacre has been presented in postwar Japan . Although
even ex-Kempeitai officers involved have admitted the killings were
inhumane and unlawful, little attention has been paid to the episode.
While there has been valuable research carried out on the Japanese
military administration of Malaya and Singapore , no reliable study has
appeared in Japan . Moreover, while the Singapore Massacre is well known
to scholars in Japan, similar killings carried out in the Malay Peninsula
only came to the attention of the Japanese public in the late 1980s after
I discovered documents relating to the Japanese military units involved.
Why did the Japanese
Military Massacre the Chinese in Singapore ?
Aspects of the Massacre
On the night of 17 February 1942 , Major General Kawamura Saburo, an
infantry brigade commander, was placed in charge of Japan ’s Singapore
Garrison. The next morning, he appeared at the Army Headquarters and was
ordered by the 25th Army commander, Lieutenant General Yamashita Tomoyuki,
to carry out mopping-up operations. He received further detailed
instructions from the chief of staff, Lieutenant General Suzuki Sosaku,
and a staff officer, Lieutenant Colonel Tsuji Masanobu. Kawamura then held
consultations with the Kempeitai commander, Lieutenant Colonel Oishi
Masayuki. The plan for a Purge through Purification of the Chinese
population was drawn up in the course of these meetings. Under this
scheme, Chinese males between the ages of 18 and 50 were ordered to report
to mass screening centers for inspection. Those regarded as anti-Japanese
were detained, loaded onto lorries, and taken away to the coast or to
other isolated places where they were machine-gunned and bayoneted to
death.
[2] In my survey
of official documents of the Japanese military at the time, I found two
sources that give a figure for the number massacred. One is Kawamura’s
diary that shows the figure of 5,000.
[3]
The other is an issue of the Intelligence Record of 25th Army
(No.62, dated 28 May 1942) prepared by the staff section of the 25th Army.[4]
This secret record states that the number missing as a result of
bombing and the purge was 11,110. This second record was important because
it was drawn up as a secret document shortly after the purge took place.
However, as this description is ambiguous and offers no basis for the
figure, its credibility is open to question. This issue remains unsettled.
The mass-screening was carried out mainly by Kempeitai personnel between
21 and 23 February in urban areas, and by the Imperial Guard Division at
the end of February in suburban districts. Most accounts of the killings
include a map that shows the island divided into four sections, and
explain that three divisions, the Imperial Guards, the 5th Division, and
the 18th Division carried out the mass screening in suburban districts.[5]
However, on 21 February, the 25th Army ordered both the
5th and 18th Divisions to move up into the Malay Peninsula and carry out
mopping-up operations there.[6] The order
assigned the Imperial Guard Division to mass-screening of non-urban areas
of Singapore , and made the 5th and the 18th Divisions responsible for the
rest of the Malay Peninsula . According to war diaries and other documents
relating to these two divisions, neither played a role in the mass
screening in Singapore . The British war crimes trial prosecuted the
commander of the Imperial Guard Division, Lieutenant General Nishimura
Takuma, on charges related to the Singapore Massacre, but not the
commanders of the 5th or 18th Divisions. This version of events is
correct, and the conventional map is wrong.
With regard to the background to the massacre, it is important to stress
that the Purge through Purification was planned before Japanese troops
landed in Singapore . The military government section of the 25th Army had
already drawn up a plan entitled, "Implementation Guidance for
Manipulating Overseas Chinese" on or around 28 December 1941.[7]
This guidance stated that anyone who would not obey or
cooperate should no longer be allowed to live. It is clear that the
headquarters of the 25th Army had decided on a harsh policy toward the
Chinese population of Singapore and Malaya from the beginning of the war.
According to Onishi Satoru,[8] a Kempeitai
officer who was in charge of Jalan Besar screening centre, Kempeitai
commander Oishi Masayuki was instructed by the chief of staff, Suzuki
Sosaku, at Keluang, Johor, to prepare for a purge operation following the
capture of Singapore . Although the exact date of this instruction is not
known, the Army headquarters was stationed in Keluang from 28 January to 4
February 1942 .

“Shukusei” was used by the Japanese Army at the time. In Chinese
community of Singapore it is usually called “Sook Ching”.
