1972 First Edition Masterpiece

The Culmination of 55 Years of Research

Tracking a lifetime of lineage training: Nawa’s original promotional marketing text proudly references 55 years of deep martial research. Born into a prominent samurai family in 1912, Nawa began his immersion into ancestral weapon scrolls and private manuscripts at roughly five years of age (1917). This book represents the complete gathering of those five decades of private, unbroken lineage study.

Scientific De-mythologizing & Technical Analysis

Forensic dissection of martial myth: Nawa weaponized his “scientific approach” in this volume to systematically dismantle commercialized cinematic fantasies. Using physical engineering principles, he famously debunked the trope of “walking on water” with Mizugumo (Water Spider) shoes, providing structural proof that they were swamp-crossing devices. The text serves as a cold, practical analysis of medieval espionage logistics.

The Ballet-Engineered Motion Photography

The body mechanics of an eccentric master: The rare black-and-white plates features Nawa Yumio personally modeling operational gear and executing high-level physical counters [hatenablog.com]. His posture reveals a highly distinct lateral pelvic turnout and precise, elongated finger extensions. These physical markers provide absolute proof of his pre-war background as a professionally trained Western-style classical ballet dancer (yōbuga).

377 Pages of Forensic Art & Archival Evidence

Preserving the material culture of the Shinobi: Every photographic flat-lay and technical ink illustration inside was arranged directly from Nawa’s private collection. The book features scarce, early public documentation of the Sendai Domain’s Karasu-gumi (Crow Group) uniform—complete with hidden iron-lattice chainmail (kusari) sewn directly beneath the dark outer cloth to defeat ambush cuts while maintaining silence.

The Fujita Seiko Publisher Link

A legendary promotional crossover: The original red obi strip lists this volume as part of a premier martial arts series, explicitly marketing Nawa’s work alongside titles by Fujita Seiko (藤田西湖)—the iconic “Last Koka Ninja”. This marketing detail cements Nawa’s position in 1972 as the absolute primary authority carrying the torch of legitimate historical espionage research into the modern era.
