A shido in judo is the minor penalty a referee gives for small infringements: passivity, a false attack, stepping out of the contest area on purpose, an illegal grip or an overly defensive posture. It gives the opponent no score. The third one, though, loses you the match by hansoku-make.
The word means "instruction". The point is to correct behavior, not to reward the other player. In practice, shido is the tool that forces judoka to actually fight.
Why the shido penalty exists
Without penalties, a lot of judo matches would turn into a static arm-wrestling contest. Shido pushes both players to engage. The referee stops the action with matte, then points an index finger at the offender with the fist closed.
Two shido cost nothing on the scoreboard. They weigh on the mind, however. A judoka on two penalties knows the next mistake ends the match, and the opponent knows it too. Many fighters change their whole game at that moment.
Shido stay on the board in golden score. They do not separate two players level on score, but a third one ends the match there like anywhere else. How the extra time works is covered in our page on golden score.
The fouls that get you a shido
Passivity and non-combativity
This is the most common shido. The referee gives it when a judoka is not attacking enough. With a standard grip, sleeve and lapel, IJF rules allow about 30 seconds to build an attack. After that, with no progress, the penalty comes. Since 2025 the referee also counts groundwork attacks when judging activity.
False attack
Dropping to the knees with no intention of throwing is a false attack. So is attacking without holding a grip, or letting go of both hands as you turn in. The question the referee asks is simple: did tori have a realistic chance to throw? Players use this move to break rhythm or escape a dangerous grip. Referees know it well.
Stepping out of the contest area
Leaving the area on purpose is penalised, standing or on the ground. Being pushed or thrown out is not. The difference is hard to judge near the edge, and the player's general attitude often decides it.
Illegal grips
Several grips are restricted:
- touching, grabbing or hooking the legs with a hand or arm in standing judo, below the level allowed;
- holding a non-standard grip (both hands on one side, the belt, a cross grip) without attacking quickly;
- bear-hugging the trunk with joined hands;
- breaking the opponent's grip with both hands without keeping at least one grip of your own.
Since 2025, gripping inside the sleeve is allowed in standing judo. Jacket grips below the belt and trouser grips up to the top of the inner thigh are also allowed, as long as you use them to attack. Grabbing the legs below that stays illegal in standing, except to follow into groundwork at the end of a throw. Moves that go beyond shido are listed in our page on illegal techniques in judo.
Defensive posture and wasted time
Bending over at the hips with straight arms to stop the opponent from coming in earns a shido. Taking your time to fix your judogi or belt between matte and hajime brings a warning first. Since the 2026 adjustment, the second time is a shido. The dress rules sit in our article on blue and white judogi rules.
Using shido as a tactical weapon
Experienced competitors know you can draw a shido from the other side. A judoka who attacks regularly makes the opponent look passive. One who holds the center and pushes gently towards the edge forces the other to back up, and the step-out eventually gets called.
Referees do not fall for everything. An attack thrown only to tick the clock over, with no kuzushi (balance breaking), can itself be judged a false attack. The line between smart judo and empty calculation is thin, and the referee draws it.
Keep an eye on the opponent's penalties late in the match. On two shido, they have no margin left. That is usually the moment to raise the pace.
What the third shido triggers
The third shido turns into hansoku-make. The match is lost. But this is disqualification by accumulation: the judoka is not thrown out of the tournament and may still fight in the repechage, depending on the draw. The difference with a direct hansoku-make is explained in our article on hansoku-make.
Shido for cadets and younger players
In the cadet age group and below, the IJF adds specific shido: using the head to throw, defending by spinning on the head, or trying a reverse seoi-nage. National federations often add their own limits for children too. Coaches need to know them, because kids commit these fouls without realizing it. The age groups are laid out in our page on judo age categories.

The habit that prevents most shido
You avoid the passivity shido long before the referee raises a finger. A judoka who attacks every twenty seconds, even with a modest ko-uchi-gari (small inner reap), almost never gets penalised. Trouble comes to the fighters who wait for the perfect chance. Set yourself one rule in randori: never two grip exchanges without an attack. After each tournament, write down which shido you got and when in the match. Most players find it is the same one, at the same moment, every time.
