About USJA
USJA (the United States Judo Association) grew out of the Armed Forces Judo Association and was formally renamed USJA in 1969. Now a cloud-based organization with 20,000+ life members, it runs its own tournament and promotion system, concentrated in California, Florida, the Midwest, and Southeast.
Rules
Judo matches are decided by ippon — a full-point score that ends the match instantly. Ippon is awarded for a throw that lands the opponent largely on their back with speed and control, for a 20-second pin (osaekomi), or for a submission by strangle or armlock in the senior divisions. Lesser throws and shorter pins score waza-ari, and two waza-ari combine to make ippon.
Modern judo rules (based on the International Judo Federation rulebook) prohibit grabbing the legs in standing exchanges, and passivity or rule infractions draw shido penalties — accumulate three and the match is lost by hansoku-make. Armlocks and chokes are age-restricted, so junior divisions are typically throws-and-pins only.
Judo tournaments in the United States are generally sanctioned by USA Judo, USJA, or USJF, all of which follow IJF-based competition rules with local modifications for youth and novice divisions. Check the event's sanctioning body and division rules before registering.
Always confirm the official rulebook before you compete — organizations update rules between seasons. See the official event page for current rules.
