Matsumiya Shunjo, better known as Matsumiya Kanzan (1686-1780) was a scholar of military science in the mid-Edo Period who wrote more than a dozen works on various aspects of military principles and strategy. Born in Ashikaga (in present-day Ibaragi Prefecture) he was sent by his parents at an early age to study in Edo where he became a student of the Hojo tradition of military science and pupil of Hojo Ujisuke. He was adopted by a samurai named Matsumiya Masatane and assumed the surname Matsumiya instead of his birth name of Maebara. In addition to military matters he also studied Confucianism, in particular Neo-Confucianism which was very important at the time. After his studies he was appointed an official surveyor to the Tokugawa Shogunate and, with Hojo Ujisuke, toured northern Japan and Ezo (modern Hokkaido) surveying the topography and studying the fortifications. He later became one of the leading teachers of the Hojo school and is credited with over a thousand pupils.
