Okinawa Kata Encyclopedia: Exploring Ryukyu's Martial Secrets is a comprehensive reference work dedicated to the history, terminology, and practice of Okinawan kata in both karate and kobud¿. Drawing on decades of study, direct training in Okinawa, and extensive historical research, this volume presents an in-depth examination of kata as the living core of Okinawa's martial culture. Organized in an accessible encyclopedia format, the book explores over two dozen classical forms, including empty-hand kata such as Sanchin, Pinan, and Kusanku, alongside kobud¿ weapon forms with the b¿, sai, tonfa, nunchaku, kama, eku, tekko, and tinbe. Each entry addresses the name's meaning and etymology, historical roots, cultural context, characteristic stances and techniques, major lineages and stylistic variations, and the kata's enduring legacy. Where sources conflict, multiple perspectives are presented with careful attention to oral tradition, documentary evidence, and modern interpretation. Beyond technical description, the encyclopedia situates kata within the broader history of the Ryukyu Kingdom and Okinawa's social and political transformations, including Chinese tributary exchanges, the Satsuma occupation, and the 20th-century evolution of karate and kobud¿ as global arts. Glossary entries clarify cultural and technical terminology, while biographies of key historical figures connect each form to the individuals who preserved and transmitted it. Intended for both practitioners and scholars, the work balances accessibility with academic rigor. Martial artists will find clear explanations of stances, movement principles, and combative strategies, while historians and cultural enthusiasts will appreciate the careful contextualization of kata within Okinawa's unique heritage. The result is a resource that bridges practice and scholarship, offering readers a structured and authoritative guide to one of the world's most influential martial traditions. At once a reference, a teaching aid, and a cultural history, Okinawa Kata Encyclopedia preserves the richness of kata as both a physical discipline and a repository of Ryukyu's martial spirit.
