What Is Japanese Jujutsu?
Jujutsu (also spelled jiu-jitsu in some romanizations) is a cluster of Japanese martial systems for close combat: throws, joint locks, pins, strikes, and — in older battlefield lineages — weapons. There is no single modern Olympic ruleset that stands for “jujutsu” the way IJF judo or IBJJF BJJ do.
Schools differ. Some are classical (koryu) survivals. Some are modern gendai systems assembled for self-defense or sport. The shared idea is using leverage and timing against a larger attacker at grabbing range.
How Jujutsu Works
A typical syllabus moves from striking or gripping into off-balancing, a throw or takedown, then control and a lock or choke. Sport offshoots specialize. Judo refined throwing and a narrower newaza set. Brazilian jiu-jitsu specialized the ground game — including the live guard family on Martial Index.
Because “jujutsu” is a family name, always ask which school and which rules you are reading about. This page is the parent-art hub, not a claim that every dojo trains the same hour.
Lineage and neighbors
Kanō Jigorō’s judo and Ueshiba’s aikido both draw on jujutsu. Brazilian jiu-jitsu grew from judo newaza after the art traveled. Hapkido and other modern systems sometimes claim related joint-lock DNA. The map is a family tree, not a single belt list.

FAQ
Questions we hear on the mats, in gyms, and when fighters compare styles.
Is jujutsu the same as Brazilian jiu-jitsu?
No. BJJ is a Brazilian sport-and-self-defense descendant that specialized ground fighting. Japanese jujutsu is the older, broader parent family.
Why the two spellings?
Jujutsu is closer to the Japanese romanization. Jiu-jitsu is a common older spelling that stuck on Brazilian and some Western school names.
The Bottom Line
Japanese jujutsu is the parent trunk. Judo and BJJ are the live, specialized branches on Martial Index — start there when you want techniques that already have pages.
