, a former Japanese diplomat was convicted and jailed by the British for spying for Japan before the Second World War. He was later credited as the "Japanese Schindler" for saving thousands of Chinese and Eurasians by his liberal issue of personal safety passes and the creation of safe havens during the Japanese occupation of Singapore. He was also instrumental for being the key prosecution witness during the Singapore War Crimes Trial between 1946 and 1948. A book he wrote after the war called Syonan—My Story, continues to give an invaluable insight into the Japanese occupation of Singapore today.
