The autobiography of Mamoru Shinozaki, 'Syonan' tells of his life during the Japanese occupation of Singapore. Sent to the colony as a press attache for the Japanese Foreign Ministry, Shinozaki saved thousands of lives through his liberal issue of personal safety passes and the creation of safe havens.

Japan attacked British-ruled Malaya on 8 December 1941 as part of a wave of military actions that toppled the British, Dutch and American colonial regimes in Southeast Asia. Within seventy days, the conquest of Malaya was complete, and British forces in Singapore surrendered on 15 February 1942. The three and a half years of Japanese rule are generally considered to mark a profound transition in the history of the Malay peninsula, but little is known about this period. This book uses the limited administrative papers that survived in Malaya, oral sources, and accounts written by Japanese officers involved in the Malayan campaign to flesh out the story.

During World War II, the Japanese government created a research bureau, the Chōsabu, to study occupied Singapore. The bureau's reports on Singapore's economy and society, reproduced here in translation, covered population and living standards, prices, wages, currency and inflation, rationing, labour usage, food production and supply, and industrialization. Syonan's military and civilian administrators drew on Chōsabu research in formulating social and economic policy. The research takes on added importance because the Japanese destroyed most records of their wartime administration. That leaves the Chōsabu reports as one of the few first-hand Japanese sources to have survived the war. The translation allows a fuller understanding of the impact of the war and occupation than hitherto possible. Introductory chapters by the editors analyse the reports in light of wartime events in Singapore and Japanese occupation policies, and discuss the Chōsabu authors and their place in the history of Japanese economic thought.
