This book represents volume one of the writings of David Sissons, who for most of his career pioneered research on the history of relations between Australia and Japan. Much of what he wrote remained unpublished at the time of his death in 2006, and so the editors have included a selection of his hitherto unpublished work along with some of his published writings. Breaking Japanese Diplomatic Codes, edited by Desmond Ball and Keiko Tamura, was published in 2013 and forms a part of the series that reproduces many of Sissonsâ€™ writings. In the current volume, the topics covered are wide. They range from contacts between the two countries as far back as the early 19th century, Japanese pearl divers in northern Australia, Japanese prostitutes in Australia, the wool trade, the notorious â€˜trade diversion episodeâ€™ of 1936, and a study of the Japan historian James Murdoch. Sissons was an extraordinarily meticulous researcher, leaving no stone unturned in his search for accuracy and completeness of understanding, and should be considered one of Australiaâ€™s major historians. His writings deal with not only diplomatic negotiations and decision-making, but also the lives of ordinary and often nameless people and their engagements with their host society. His warm humanity in recording ordinary peopleâ€™s lives as well as his balanced examination of historical incidents and issues from both Australian and Japanese perspectives are a hallmark of his scholarship.
