Jutsu and Dō in Japanese Martial Arts
Jutsu and dō are recurring terms in Japanese martial-art names, but spelling, history, institutions, and actual curricula matter more than suffix alone.
Martial Arts
Brazilian Jiu-Jitsu
Brazilian Jiu-Jitsu is a Brazilian grappling art and combat sport developed from Kodokan judo and jujutsu transmitted to Brazil in the early twentieth century.
Japanese Martial Arts
Japanese martial arts encompass classical combat traditions, modern budō, Okinawan karate, weapons practice, grappling, competition, and systems of physical and ethical education.
Judo
Judo is a modern Japanese martial art and educational practice built around throws, groundwork, kata, randori, safe falling, and mutual benefit.
Jujutsu (Jiujitsu)
Jujutsu is a diverse family of Japanese close-combat traditions, not one universal syllabus and not simply another name for Aikido or Brazilian jiu-jitsu.
Aikido
Aikido is Morihei Ueshiba’s modern Japanese budō, historically rooted in Daitō-ryū yet institutionally and philosophically distinct from aiki-jūjutsu.
