Work on the revised and expanded edition of Samurai Revolution is now nearing completion. Since the original publication, I have continued researching the Bakumatsu and Meiji Restoration through expanded use of Japanese primary sources, including the journals, memoirs, letters, and historical writings of Katsu Kaishū, letters of Sakamoto Ryōma, Nakaoka Shintarō, and other leading figures of the era, contemporary accounts relating to Kaishū and other important men on both sides of the revolution, as well as authoritative scholarship on the era and its principal figures.

The new edition incorporates this research throughout the text. It also includes revised translations where closer study of the original Japanese warranted them, a second appendix, and new maps. My aim has been not simply to update the book, but to deepen its historiography while making this extraordinary period of Japanese history even more vivid and accessible.

Before the revised edition of Samurai Revolution appears in spring 2027, Samurai Swordsmen: The Definitive History of the Shinsengumi amid the Fall of the Tokugawa Shogunate (1863-1869) will be published by Helion this September.
