Kanō Jigorō
Gendai budō have origins in "koryū", the traditional Japanese martial arts. For example, Kano Jigoro (嘉納 治五郎 "Kanō Jigorō", 1860–1938) founded judo in part as an attempt to systematize the myriad traditions of jujutsu which existed at the time. Kendo similarly derives from the many schools of kenjutsu that evolved over the centuries.
