With over 900 years of history and tradition, Ninjutsu was born from the need to survive – evolving in response to the reality of conflict and war. Throughout this time, techniques and principles were developed and realised through actual combat, and so the nine schools of Ninjutsu began to form. Many of these schools were studied by the Samurai, some schools specialising in battlefield warfare, others in empty handed jujutsu or weapons. The eight schools along with one ‘pure’ Ninja school form todays Ninjutsu which collectively offers a wide range of realistic, authentic techniques, strategies and martial arts principles.
