Yagyū Shingan-ryū
, is a traditional school (koryū) of Japanese martial arts. Different styles of Yagyū Shingan-ryū, such as Heihojutsu and Taijutsu, assert different founders, Takenaga Hayato and Araki Mataemon respectively, but they all go back to Ushū Tatewaki (羽州 帯刀), referred to in some historical scrolls as Shindō Tatewaki, who taught a system based on Sengoku-period battlefield tactics, that was called Shindō-ryū.
