Article 14 – lppon

Evaluation of the points in Nage-waza.

The four criteria for ippon are speed, force, on the back and skilfully controlled until the end of the landing.

  1. lppon will be given when the contestant throws his opponent on the back, applying a technique or countering his opponent’s attacking technique, with considerable ability with maximum efficiency (*).

* “ikioi” = momentum with both force and speed and “hazumi” = skilfulness with impetus, sharpness or rhythm.

Rolling can be considered ippon only if there is no break during landing. The difference of the rolling makes the evaluation of the points. It is lppon when uke rolls on his back.

  1. All situations in which one of the contestants deliberately makes a “bridge” (head and one foot or both feet in contact with the tatami) after having been thrown will be considered ippon.

  • This decision is taken for the safety of the contestants, so they do not try to escape from the technique and endanger their cervical spine. Also, an attempt of a bridge (arching the body) should be counted as a “bridge•.
  • No score or penalty will be given if the landing of uke occurs on the body of tori, in such a way that not all parts of uke’s body involving the bridge situation {head, foot or feet) touch the tatami.

Evaluation of the points in Katame-waza

  1. When a contestant holds with osaekomi-waza the other contestant, who is unable to get away for 20 seconds after the announcement of Osaekomi!.
  2. When a contestant gives up by tapping twice (2) or more with his hand or foot or says Maitta! (I give up!) generally as a result of osaekomi-waza, shime-waza or kansetsu-waza.
  3. When a contestant is incapacitated by the effect of a shime-waza or kansetsu­ waza.

Should one contestant be penalized with hansoku-make, the other contestant shall immediately be declared the winner with a score equivalent to ippon.

Special situations

  1. Simultaneous techniques – when both contestants fall to the tatami after what appears to be simultaneous attacks and the referees cannot decide which technique dominated there should be no score awarded.
  2. In the case where both contestants score simultaneous ippon the referee will act as regulated in article 13 paragraph b.
