Combat sports
Judo
Judo rewards efficient use of balance, leverage, timing, and controlled grappling rather than striking. A decisive technique can end the contest immediately, while lesser scores and penalties shape the remaining bout.
At a glance
- Freestyle practice is called randori.
- Belts communicate grade, although color sequences vary by region.
- The rules favor active attacking judo over defensive stalling.
Player profile. Judoka need grip strength, explosive hips and legs, balance, flexibility, falling skill, tactical patience, and confidence in close contact. Breaking balance usually precedes a throw, so hands, hips, and feet must coordinate before strength is applied. Safe falling lets athletes train at intensity and recover immediately into pins, chokes, or elbow locks.
Where it happens
A square contest area on tatami, with a central fighting zone and surrounding safety area; international layouts use a regulated mat size. Tatami absorb impact while the central contest zone and surrounding band give officials a clear reference for action near the edge. Jackets provide durable gripping points that shape both standing attacks and groundwork.

How to play
- Grip the opponent's jacket legally.
- Create imbalance and attempt controlled throws.
- Continue into pins, chokes, or arm locks where allowed.
- Seek ippon or lead on scores when time ends.
The essential rules
- A clean controlled throw onto the back can score ippon.
- A qualifying hold-down can also produce ippon after the required duration.
- Two waza-ari combine into ippon under the described system.
- Legal submission techniques are limited to permitted chokes and elbow locks.
- Strikes are not allowed in contest judo.
- Gripping and passivity rules encourage active attacks.
- Stepping outside or avoiding engagement may be penalized.
- Dangerous throws or attacks against prohibited joints are illegal.
- A referee can stop the action for safety or reset.
- Ippon ends the bout immediately.
How the result is decided
Ippon wins outright; waza-ari recognizes a near-decisive action, and penalties can decide an otherwise tied contest. Ippon represents a complete result and ends the bout; waza-ari records an action that falls short of that standard. Penalties influence close contests, but the scoring system is designed to favor decisive controlled technique.

How the sport developed
Jigoro Kano organized judo in nineteenth-century Japan from older jujutsu methods, emphasizing education and controlled practice. The resulting system retained throws and submissions while excluding battlefield strikes from sporting bouts.
- A scoreboard traditionally abbreviates the principal scores by their initial letters.
