The book is devoted to most ancient confirmed style of bujutsu and ninjutsu of district Iga, which has more than thousand year old history, and which formed a basis for many styles of martial arts generally, and several styles of ninja taijutsu in particular (Iga ryu, Hakuun ryu, Togakure ryu, Koto ryu, Gikan ryu, Gokushin ryu etc.)
Nowadays Gyokko ryu koshijutsu is the base of training of Bujinkan dojo. In the new book the first time are examined all theoretical and practical aspects of the style, the entire history and denkey (transfer line of the doctrine), the principles and theory, and also full technical arsenal (mokuroku) of "Jasper tiger" style. The book has no analogues in the world by quantity of information and illustrative material (more than 500 photos). All names, terms and philosophical principles in the book are doubled in Russian and Japanese: more than 1000 hieroglyphs.
The book is intended for followers of Bujinkan system, as well as for everyone seriously interesting in Japanese martial arts.
Great book, lots of details and an enjoyable read. A must for students of the Bujinkan, Jinenkan and Gembukan. Hopefully Momot will translate his other books.
