A Shinkage-ryū offshoot carried into the present
Komagawa Kaishin-ryū (駒川改心流) is a school of Japanese swordsmanship founded by Komagawa Tarōzaemon Kuniyoshi, later known as Komagawa Kaishin, who built it upon the Shinkage-ryū of Kamiizumi Nobutsuna. It is one of the older sword traditions to have been transmitted continuously, and its curriculum preserves an archaic style of fencing.
A founder of the age of Kamiizumi
Komagawa Kuniyoshi belonged to the generation shaped by Kamiizumi Nobutsuna's Shinkage-ryū, and his school stands as one of the several lines that grew from that influential source. As with many traditions of its age, the fine detail of its earliest generations is recorded chiefly through the school's own transmission, so Ryūpedia treats the founding period with due caution.
An old sword kept alive by careful hands rather than reputation.
Transmission in the Kuroda line
Komagawa Kaishin-ryū is transmitted today as part of the Kuroda family body of classical martial arts in Japan, alongside several other koryū preserved within that lineage. Through this line the school continues to be taught as a living classical tradition.
