<Abstract>
As a representative inheritor of the newly discovered ancient martial arts schools that were prevalent in the Mito Domain during the Bunsei period, namely the Yiga-ryu and Asayama Ichiden-ryu, Fujisaki Tominojo Koremichi can draw on the ancient family documents. In addition, in a letter written by Takeishi Kensou, a former samurai of the Mito Domain, to his disciple Matsumoto Mitsugu in the 18th year of the Showa era, focusing on the comparison of the forms and contents of the transmission documents of the Muhi-ryu, Asayama Ichiden-ryu, and Kensou-ryu, and considering the characteristics of the martial arts inheritance, and at the same time incorporating supplementary information such as the oral history passed down by relatives and disciples, an attempt is made to verify the changes in martial arts that were prevalent among the samurai class from the late Edo period to the early Showa era, as well as the spirituality of martial artists.
