Tenshin Shoden Katori Shinto-ryu is one of the oldest traditional Japanese martial arts, founded in the 15th century. It encompasses a wide range of techniques, including swordsmanship, staff fighting, and grappling. The school emphasizes the development of both physical skills and mental discipline. The art is rooted in the teachings of Choisai Ienao, who established the style in Katori Shrine, a sacred site in Japan. Practitioners learn various kata (forms) that reflect historical combat techniques, aiming to preserve the martial heritage and philosophy of the samurai.
