I owe a great debt to so many people who supported me during the years it took to research and write this book, but I must place Josh Fogel, Luke Roberts, and Tsuyoshi Hasegawa at the top of the list. From the three of them, I learned so much about how to be both a disciplined scholar and a passionate teacher. E. Bruce Reynolds of San José State University and Jeffrey Hanes of the University of Oregon also deserve special recognition, as the time I spent working with them during the early years of my academic training had an indelible impact on the historian I am today. Special gratitude also goes to Mark Peattie, Frederick Dickinson, Daniel Botsman, Tak Matsusaka, and Bill Sewell for their enthusiastic participation in several conference sessions related to this project and to David Ambaras for his close and insightful reading of the original manuscript. For their involvement in many other workshops and meetings where I presented my research on the Japanese consular police, let me thank in particular Jun Uchida, Eiko Maruko Siniawer, Robert Cribb, Joseph Yick, Rustin Gates, Emer O’Dwyer, Robert Perrins, Aaron Skabelund, Thomas DuBois, and Marieke Bloembergen. From my years as a graduate student at the University of California, Santa Barbara, special thanks go to Shao Dan, Laura Nenzi, and Chip Dewell for their friendship and advice. I also feel so fortunate now to be a part of an intellectually rich and personally supportive group of colleagues in the Department of History at the University of Vermont.
The research for the dissertation that became this book was made possible by a fellowship award from the IIE Fulbright Program and the Japan-U.S. Education Commission. In Japan, Professor Hirano Ken’ichirō of the Graduate School of Political Science at Waseda University was a kind and generous host during my stay there as a graduate student researcher, and during the years since he has graciously sponsored several important short-term stints for me at Waseda to carry out follow-up work. Heartfelt thanks are also due to Professor Mizuno Naoki of the Institute for Research in Humanities (Jinbunken) at Kyoto University and the members of his consular police research group, especially Matsuda Toshihiko, Asano Toyomi, Soejima Shōichi, and Ishikawa Yoshihiro. I must also thank Professor Ogino Fujio of Otaru Commercial University for his advice and suggestions during our several meetings in Tokyo, and for his continued interest in and support of my work. Additional financial support over the (p.xii) years was provided by the University of California Pacific Rim Research Program, the History Department and Graduate Division at UC Santa Barbara and the Regents of the University of California, the Asian Studies Program, Dean’s Office of the College of Arts and Sciences, and Department of History at the University of Vermont, and the Northeast Asia Council of the Association for Asian Studies.
Passages within this book appeared previously in somewhat different form as segments of journal articles in Modern Asian Studies and Intelligence and National Security. I thank the editors of both journals for allowing me to reshape some of that content here. I am also so grateful for the consistently enthusiastic attention shown to this project by Patricia Crosby and her editorial team at the University of Hawai`i Press from the moment of my initial proposal until the final production of the book. The superb comments offered by the press’ anonymous reviewers, too, made this a much better book than it would have been otherwise. The weaknesses that might remain are my responsibility alone.
Finally, this book (and my entire career as a professional historian) would never have been possible without the love, patience, and unwavering support of my wife, Megumi. Without her and our children in my life, all of this would not mean a thing to me.
