What Is a Judo Scoreboard?
A Judo Scoreboard is an online scoring system that shows martial arts match results. It tracks scores, penalties (Shido, Hansoku-make), match time, and more.

With one click, you can update results instantly, just like official tatami refereeing systems.

Judo Scoring Point Table
In judo competition rules (set by the International Judo Federation), the scoring system rewards clean, powerful, and decisive techniques.
Here is a breakdown of the point system used in international judo competitions (based on recent rule changes):
| Score Term | Value | How It Is Awarded |
| Ippon | Full Point | The match ends immediately. Awarded for: <br> • A perfect throw that lands the opponent flat on their back with force and speed. <br> • Pinning an opponent with their back on the mat for 20 seconds. <br> • Forcing an opponent to submit with a chokehold or an armlock. <br> • The opponent is disqualified (Hansoku-make). |
| Waza-ari | Half Point | Awarded for: <br> • A throw that is successful but lacks one of the criteria for an Ippon (e.g., less force, or the opponent lands on their side). <br> • Pinning an opponent with their back on the mat for 10 to 19 seconds. <br> Two Waza-ari scores combine to make a full point, ending the match (Waza-ari Awasete Ippon). |
| Shido | Penalty | A "Shido" is a warning for a minor rule infringement, such as being overly defensive, non-combative, or avoiding grips. <br> • The first two Shido are warnings. <br> • A third Shido results in Hansoku-make (disqualification) for the competitor, and the opponent wins by Ippon.1 |
Key Points to Understand:
- Priority of Scores: The highest-value score always takes precedence. An Ippon ends the match immediately, regardless of Waza-ari scores.
- Golden Score: If the match ends in a tie, the fight continues into Golden Score sudden death overtime. The first competitor to score Ippon or Waza-ari wins.
- No Lower Scores: Past scoring terms such as Yuko and Koka have been removed under modern IJF rules, simplifying the system and encouraging decisive throws.

FAQs About a Judo Scoreboard
A Waza-ari is a half-point. It is awarded for a throw that is missing one of the criteria for an Ippon (e.g., a throw with less force, speed, or control). It's also given for pinning an opponent for 10-19 seconds.
An Ippon is a full point, and it immediately ends the match. It can be awarded for a "perfect throw" where the opponent is thrown with speed, force, and control, landing flat on their back. An Ippon can also be awarded for holding an opponent down for 20 seconds, or by forcing a submission through a chokehold or an armlock.
The main scores are Ippon and Waza-ari. An Ippon is the highest score, and a Waza-ari is a lesser score. The scoreboard also tracks penalties (Shido) and the time remaining in the match.
Yes, the scoring system has evolved. In the past, there were other scores like "Yuko" and "Koka," which were smaller than a Waza-ari. These were removed in recent rule changes to simplify the scoring and encourage more decisive actions, making the scoreboard easier for spectators to understand.
According to current rules, if a competitor receives two Waza-ari, the scores add up to a full point, which is called "Waza-ari Awasete Ippon" (meaning "two Waza-ari make one Ippon"). This immediately ends the match, just like a single Ippon.
A Shido is a penalty given for minor rule infractions. These infractions can include being overly defensive, avoiding grips, or stepping out of the designated area. The scoreboard displays a numerical count of Shido for each competitor.
A competitor can receive up to three Shido. The first two are warnings. If a competitor receives a third Shido, it results in a "Hansoku-make" (disqualification), which means their opponent wins the match.
"Golden Score" is a sudden-death overtime period. It is used if the scores are tied at the end of the regulation match time. The clock is reset, and the first competitor to score a point (Ippon or Waza-ari) or whose opponent receives a penalty (Shido) wins the match.
A timer on the scoreboard tracks the duration of a pin. A hold that lasts for 10-19 seconds results in a Waza-ari, while a hold lasting 20 seconds or more is awarded an Ippon, which ends the match.
In addition to scores, penalties, and time, a judo scoreboard often displays the names and nationalities of the competitors, the weight category, and the match number. Some advanced scoreboards may also show real-time statistics or replays.
