The Tokugawa shogunate managed to bring stability to the nation, marking the end of a long period of inner conflict. The armored battlefield tactics naturally evolved into more practical self-defense methods relevant to the locale and social climate. The Taijutsu school was created by Hoshino Tenchi, 8th generation headmaster and is known for its close quarter jujutsu grappling techniques, which require a clear understanding of taijutsu (body movement). In this context, taijutsu refers to the underlying principles of body dynamics, rather than the physical techniques themselves. As the name jujutsu or yawara implies, they are essentially soft techniques and should not require a great deal of brute strength. The aggressiveness of the style remained the same. Some of the trade-mark maneuvers include pole-driving (dropping an opponent on his head), back breaking, and neck snapping. Although the Edo-line of Yagyu Shingan-ryu does not employ the wearing of armor during practice or exhibition, the techniques are clearly related to armored combat. The style includes the usual array of weapons forms, but is distinguished by its unique staff (6 ft) and ōdachi kata.
