Okuri ashi barai Ė How I think it should be taught.
First watch this truly sublime video of Okano sensei practicing Okuri ashi barai.

Now this video is probably how most of you have been taught and practice Okuri ashi barai

First of all Iím not saying that the above method is wrong or that it is bad technique. However, I believe the method shown in the Okano video is better , more realistic and incorporates key principles better.
So letís look at what Okano does differently. Well he practices the technique against an uke who is retreating in a straight line and then he performs a large outward step diagonally to his right causing uke to adjust his movement pattern and creating a reaction that makes a perfect moment of opportunity for Okuri ashi barai.
Okano begins advancing towards his retreating uke following a normal stepping pattern:
Beginners an important note. In ashiwaza drills tori should always establish the pace of the practice. Also many beginners mis-step so tori advances with his left uke retreats with his left.
To set a good rhythm and ensure that a correct stepping pattern is in place, assuming a right hander practicing with another right hander, rotate your sleeve hand slightly away from you and push straight forwards as if your forearm was a piston. You perform this action simultaneously with you stepping forward with your left foot. This not only ensures uke reacts appropriately, but also signals your clear control of the rhythm and direction of movement.
After several steps Okano is comfortable with the rhythm and is ready to initiate the action-reaction sequence.
Stepping normally with his left he prepares to take an exaggerated step diagonally outwards with his right.
Seen from another angle:
Mid way through the diagonal step
The full extent of just how deep a diagonal step Okano takes, this is more for demonstration and practice purposes than for randori. To drill the concept into your movement.
This action sets in motion ukeís reaction which is to adjust his stepping pattern in a way that will bring his feet together. Simultaneously it creates a situation of what I pompously call Ďdynamic delayí.
The red charts the direction of ukeís right foot towards his left.
Dynamic delay is very hard to capture in words or in still images, however, if you watch the video again you will see what I mean. The concept is also well demonstrated in this video

Especially at around 1:40.
Okano, in possession of perfect timing, utilises this dynamic delay to bring his sweeping foot through so that it catches ukeís retreating right foot at the perfect moment.
Seen from a different angle
The action reaction sequence set in process by the diagonal outwards step allows Okano to accelerate the motion of the unweighted retreating right foot with his sweeping foot so that it contacts ukeís left foot as it is being unweighted, but before the right foot can be re-weighted.
As this image demonstrates ukeís feet are now totally unweighted and Okanoís sweeping action takes them both clear of the floor.
From a different angle:
The inevitable occurs, a beautiful ippon throw.
Now, after that waffle breakdown, why I believe this to be a better model for teaching and practicing Okuri ashi barai.
Firstly pace, pace and rhythm are fundamental to ashiwaza. In the usual method of the sideways skipping pace management by tori becomes very difficult. Uke and tori end up either in a race together to see who can do it the fastest, or completely at odds leaving tori either too far ahead or too far behind uke. The advantage of the straight walk then diagonal step method, catchy name I know, is that tori has complete control over the pace throughout and can pick his moment to initiate the diagonal step when he is comfortable with the rhythm of the drill.
Hands and feet, because of the pace problems outlined above the sideways skip method means itís very difficult for people to coordinate their hands and their feet because theyíre usually in such a muddle over getting the feet right the hand action goes out the window or vice versa. Because of toriís control over the pace and moment of attack the ability to coordinate the hands and feet is much increased.
Also the drill can be broken down into stages, first walking through with a partner developing just the diagonal step, with only the hands resting on each other. Then walking through incorporating a gentle sweeping action brining the two feet together rather than a full sweep, with only the hands resting on each other. Then you can bring in the proper grips with a gentle sweep, working on coordinating kuzushi and the foot action. Then proper grips with a full sweep. This incremental method takes longer, but is a much richer learning process developing the key coordination and movement skills at each step.
Realism. One of my major gripes with the sideways skipping drill is that people get their lesson on it then when randori comes they immediately try taking over 9000 sideways skips to get the rhythm. Their opponent isnít a retard and knows what theyíre trying to do and doesnít co-operate and the result is total failure, disappointment combined with a sense of being misled and abandonment of the technique.
Using the method in the Okano video is better because it teaches Ďleading ukeís mindí and the key principles of changing direction, pace and understanding of weight transfer that are required for good ashiwaza. The awareness that it isnít about gallivanting round the mat like a prize stallion and that the key lies in subtlety and awareness of movement and moment of opportunity is a much better ashiwaza mindset to instill and much more realistic for randori and competition.
So to close, I donít believe the side skip method is wrong or bad practice or that no one can learn Okuri ashi barai from it. However, I believe its quite a difficult drill and is easily abused and misunderstood by beginners and not so well informed coaches. I believe the method demonstrated in the Okano video is simpler, easier to learn and teaches the fundamentals more effectively.
As a final thought Iíll leave you with this video of Osawa senise now 10th dan then 8th dan teaching Okuri ashi barai.
