Judo scoring: the complete guide

The scoring system in judo has been simplified in recent years by the International Judo Federation (IJF). Today, there are only two possible scores and a penalty system. Here's the complete guide.

The scores

Ippon (immediate victory)

An ippon ends the fight immediately. It is awarded when:

  • Throw: the opponent lands on their back with force, speed and control
  • Pin: 20-second hold on the ground (Osaekomi)
  • Submission: opponent taps out from an armlock or choke

One single ippon and the fight is over. It's the ultimate goal in judo.

Waza-ari (half point)

A waza-ari is awarded when:

  • The throw is missing one of the ippon criteria (e.g., landing on the side)
  • Pin held between 10 and 19 seconds

Important: two waza-ari = ippon (fight over).

Penalties (Shido)

Penalties are given for non-combative behavior or rule infractions:

  1. First shido: warning (no score)
  2. Second shido: warning (no score)
  3. Third shido: hansoku-make (disqualification, waza-ari awarded to opponent)

Common faults

  • Passivity: not attacking for too long
  • False attack: simulating a technique without real intent
  • Stepping out: voluntarily leaving the contest area
  • Leg grab: directly grabbing the opponent's legs (banned in standing)
  • Excessive defensive posture: bending too far forward

Golden Score

If regulation time ends with no score, the match goes to golden score: unlimited overtime where the first score or penalty decides the winner.

This is often where fights are decided and where physical conditioning makes the difference.
