Kobushin Kai (“Ancient Martial Spirit” Association) is a school of martial arts, the primary goal of which is to teach Goshinjutsu (Self-Defense Techniques). This unarmed form of combat, descended from the empty-hand techniques used by the Samurai on the battlefields of ancient Japan, has since evolved into a highly effective method of individual self-protection. Goshinjutsu essentially describes
a range of techniques that utilize Atemi no Jutsu (striking techniques) and Jūjutsu (grappling, throws, joint locks and chokes) to overcome an opponent. Countless styles have described their respective arts as forms of Goshinjutsu, yet, even though many of them share similar or sometimes even identical techniques, each style has its own unique emphasis, curriculum and philosophy.
