How it works
| Score | From a throw | From a hold-down | Scoreboard |
|---|---|---|---|
| Ippon | On the back with speed, force and control | 20 seconds | 100 |
| Waza-ari | The four ippon criteria not fully met; or a landing on the whole side of the body, past 90 degrees at the shoulders but not on the back | 10 to 19 seconds | 10 |
| Yuko | A side landing at 90 degrees or further to the front; on the upper back; on the side with one elbow or hand down; on one or both buttocks; on the neck | 5 to 9 seconds | 1 |
- A second waza-ari for the same athlete is waza-ari-awasete-ippon, and the contest ends.
- Yuko are counted one by one, but "they do not add up to waza-ari". Any waza-ari therefore outranks any number of yuko.
- No yuko is given if the front of the stomach, the front of both hips or both knees touch the mat first or at the same moment as a side landing.
- No yuko is given if two elbows, arms or hands touch at the same moment as the buttocks or side.
- As with ippon, the action must be continuous. If it stops, there is no score.
Tricky cases
How many yuko equal a waza-ari?
None. Yuko are counted but never add up to a waza-ari.
An athlete was thrown and landed face down on the stomach. Is that a score?
No. A landing on the front of the stomach is not a yuko.
Is yuko a current score?
Yes, in this edition of the IJF rules. It was absent from the rules for some years before.
Why the rule exists
Not every good throw is a perfect one. The lower scores give the referee a way to credit a throw that worked but fell short, and give a contest a result without waiting for an ippon.
