First published in 1920, this is book four of a seven-volume course on leaning jujitsu, comprising lessons 12-18. Jujutsu, also referred to as Jujitsu or Jiu-Jitsu, is a Japanese style of martial art and close combat that concentrates on defeating an armed opponent both with or without a short weapon. "Ju" means soft or flexible, while "Jutsu" means "art" or "technique" and refers to the use of your opponent's force against themselves. This volume contains useful illustrations and simple, clear instructions for the positions and manoeuvres treated, as well we chapters and explanations on general principles and keeping your body in shape. "The Secrets of Jujitsu" will appeal to those looking to begin their jujutsu path, and it is not to be missed by collectors of vintage literature of this ilk. Contents include: "Lesson 12", "Lesson 13", "Lesson 14", "Lesson 15", "Lesson 16", "Lesson 17", and "Lesson 18". Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.
