Tenshin Bukō-ryū heihō (天真武甲流兵法) is a Japanese koryū martial art which has its roots in the Toda-ryū, founded in the late Muromachi period c. 1560 by Toda Seigen (戸田 清眼).
From Ryōsuke and Sato-o, Toda-ha Bukō-ryū divided into two lines, one located in its ancestral home in Chichibu and the other in Tokyo.
Only one of her students, Kobayashi Seio, continued the line, which she then passed to Nitta Suzuo, the 19th generation sōke.
Before his untimely death, Nakamura appointed Kent Sorensen, director of central Funabashi dojo in Chiba, Japan, as sōkedairi of Toda-ha Bukō-ryū.
In 2022, Sorensen, with the support of all shihan (licensed instructors), initiated a second renaissance of the school, changing the name to Tenshin Bukō-ryū heihō.
