Yagy Shinkage-ry is one of the oldest Japanese schools of swordsmanship (kenjutsu). Its primary founder was Kamiizumi Nobutsuna, who called the school Shinkage-ry . In 1565, Nobutsuna bequeathed the school to his greatest student, Yagy Munetoshi, who added his own name to the school. Today, the Yagy Shinkage-ry remains one of the most renowned schools of Japanese swordsmanship. Its name roughly means Yagy New Shadow School. At the time of its founding by Kamiizumi Nobutsuna, the superiority of a school was determined through duels. Basic postures were distinct; a very low stance was maintained, in the interest of protecting the body. The idea of winning at any price was deeply ingrained in the schools of the time, as were the concepts of Isatsu-no-tachi (the school of the sword that kills only once) or Ichi-no-tachi (the sword of only one cut). A great deal of importance was placed on the technology of swords and armor themselves. However, with the arrival of muskets (arquebuses) and other elements of modern warfare, these traditionally invincible techniques were no longer sufficient.
