Osaekomi

Article 17 – Osaekomi-waza

Evaluation of ippon in osaekomi-waza is given when a contestant holds the other contestant who is unable to get away for 20 seconds, waza-ari is given for 10 seconds or more but less than 20 seconds.

The referee shall announce Osaekomi! for an applied technique when the contestant being held:

  • is controlled from the side, rear or on top by his opponent and
  • has his full back or complete upper back (scapular region) in contact with the tatami

The contestant applying the hold must not have his leg(s) or body controlled by his opponent’s legs.

The contestant applying the osaekomi-waza must have his body on and over the opponent’s body covering it and holding the opponent down underneath his body.

He must apply pressure onto the opponent’s front upper body with his front upper body in either the kesa, the shiho or ura position, i.e. similar to the techniques kesa-kami-shiho-ura-gatame and sankaku situations.

Should a contestant who is controlling their opponent with osaekomi-waza, change without losing control, into another osaekomi-waza, the Osaekomi! time wil continue until the announcement of ippon (or equivalence), Toketa! or Matte!.

When osaekomi-waza is being applied and tori commits an infringement meriting a penalty (shido):

If the Osaekomi! time is less than 10 seconds, the referee shall announce mate, return the contestants to their standing positions, award the penalty then recommence the contest by announcing Hajime!.

If the Osaekomi! time is 10 seconds or more, but less than 20 seconds, the referee shall announce Mate!, return the contestants to their standing positions, award the contestant who was in an advantageous position with the penalty {shido) and the score (waza-ari); then recommence the contest by announcing Hajime!.

However, should the penalty to be awarded be hansoku-make, the referee shall, after announcing Sono-mama!, consult with the IJF Supervisors and/or IJF Refereeing Commission, announce mate to return the contestants to their starting positions, then award hansoku-make and end the contest by announcing Sore­ made!.

When Osaekomi! is being applied and uke commits an infringement meriting a penalty, the referee shall announce Sono-mama!, award the penalty, then recommence the contest by touching both contestants and announcing Yoshi!.

When the situation permits and in order not to interrupt the positive action of tori, the referee will award directly the penalty pointing uke without interrupting the contest with Sono-mama!.

Toketa

Toketa! should be announced if, during Osaekomi, uke succeeds in “trapping” the leg(s) of tori, either from above or from below the leg.

The referee should pay attention to the following situations where Osaekomi is still valid and Toketa! must not be announced, for example, where the back of the contestant being held is no longer in contact with the tatami, (e.g., “bridging”), but the contestant applying the hold maintains control.

If uke escapes from osaekomi-waza outside the contest area:

  • •The referee must call Mate! if there is NO immediate continuation from either tori or uke in applying osaekomi-waza, shime-waza or kansetsu-waza and, if the case, assign the relevant osaekomi-waza score.
  • The referee must call Toketa! if there is an immediate continuation from either tori or uke in applying osaekomi-waza, shime-waza or kansetsu-waza, and, if the case, assign the relevant osaekomi score, leaving this last action to continue.

This kind of osaekomi-waza is not valid and the referee must call Mate! if there is no progression in the action.

This kind of osaekomi-waza is not valid and the referee must call Matte! immediately.

It is never allowed to hold an osaekomi-waza just around the head/neck without control of at least one arm.  Control in newaza using arms or legs around the neck without the opponent’s arm inside will be considered as Matte!
