De Ashi HaraiHow it works and how to improve it

01 / AT A GLANCE

Sweep the step before it becomes a stable support

De-ashi-harai is an ashi-waza in which a stepping foot is swept during its change of support. Its common English translation is forward foot sweep, but the opportunity is not limited to an opponent walking straight forward. The important relationship is between the foot’s movement, the arrival of body weight and the direction created through the upper body. A foot that looks exposed may already be too firmly planted for the sweep you intended.

Convention: you are tori, your partner is uke. Begin with your left hand controlling uke’s right sleeve and your right hand holding uke’s left lapel. This guide’s first example uses your left sole against uke’s advancing right foot. The other side is a separate mirrored exercise. Calling this a left-foot action avoids confusing the attacking foot with your usual right-handed grip.

De ashi barai, de-ashi-barai and deashi harai are common search spellings for this technique. They do not require separate pages or imply separate official throws. For an overview of its place among leg techniques, use the official technique reference. Here the focus is how to recognise a usable step and improve the decision that precedes contact.

This is a supervised practice guide for judoka who can receive a controlled fall. The first learning goal is a well-timed, comfortable contact with an organised standing base. A spectacular airborne finish is neither necessary nor a useful beginner target. Your partner should never have to jump to make a mistimed sweep appear successful.

02 / WATCH THE TECHNIQUE

Watch weight transfer, not just the sweeping foot

The Kodokan video supplies the formal demonstration. Efficient Judo’s second video is a demonstration reference, not a spoken troubleshooting lesson. Compare the actions without assuming that every grip, direction or tempo is identical. First watch the partner’s moving foot; next watch the torso; finally connect the two observations. The instructional questions below are prompts for your viewing and training, not claims that these publishers endorse this particular programme.

Pause your own practice footage immediately before contact. Is uke’s right foot travelling, touching lightly, or already supporting a settled body? A single still frame cannot show weight directly, so compare the preceding and following frames and ask uke how the contact felt. A smooth displacement and a collision with a planted ankle are different events even when the contact location appears similar.

Then watch tori’s standing leg and head. Does the base travel with the partner, or does the sweep begin after tori has fallen behind? Looking down continuously can leave the upper-body connection passive. Try watching the chest while sensing the step through the grips; use the camera afterward to check whether your perception matched the movement.

Do not copy an apparent hand jerk without its approach. A short visible action may be the final part of an earlier change in rhythm. Record which foot was moving and which direction the pair travelled before trying to reproduce the finish. That description is more useful to a coach than “I want my sweep to look faster.”

03 / WHEN TO USE IT

Look for a step you can influence

An advancing right foot

Begin with uke taking a small, agreed forward step. You move with the partner and meet the right foot near the end of its travel, before it becomes a reliable support. If you wait until the body settles above it, the same sole contact may feel heavy and immovable. Change the timing, not the force, when this happens repeatedly.

A recovery step after a genuine threat

An attack that makes uke recover their stance can offer a moving foot. For example, a controlled sasae-tsurikomi-ashi threat may produce a step that you can follow. The recovery is the cue; the mere fact that you attempted sasae is not. If uke stays planted, restore your stance and choose another task.

A retreat that you can follow

The official definition includes backward as well as forward stepping. Learn a retreating-foot version separately with your coach, because the contact direction and distance change. Do not extend the same left-foot sweep farther and farther while the partner moves away. Following the body first gives the foot action a realistic chance to influence support.

When the opening is absent

A wide, settled stance, a lost sleeve connection or an opponent beyond comfortable reach can remove the current opportunity. Recognising that absence is part of skill. You can still move, adjust grips or threaten another direction, but repeated ankle taps from the same failed distance seldom teach the timing problem you meant to solve.

04 / HOW IT WORKS

Connect the foot’s travel with the upper-body turn

Arrive beside the step

Move your supporting right foot so your left leg can act without reaching from a collapsing stance. There is no universal distance in centimetres: partner size, step length and direction alter the fit. In a slow drill, stop just before contact and check whether you could remain upright if the sweeping foot returned to the mat immediately.

Make broad, controlled sole contact

Shape the left foot so the sole meets the lower part of uke’s right foot or ankle in the demonstrated line. The action should move the foot along the mat rather than strike upward into the shin. Let your coach inspect the precise contact. Curling the toes alone is not a substitute for having the whole leg and body in the correct relationship.

Sweep through the changing support

Continue the foot’s available movement while the grips guide the upper body into a fall. The arms should contribute to a coordinated turning action, not pull uke straight onto a foot you are trying to free. If the hands and foot oppose each other, the ankle may become loaded at the very instant you want it to move.

Remain responsible for the landing

Keep the sleeve connection and guide the partner’s fall without wrenching the shoulder. Your own support should remain available as the swept leg returns. When a throw does not develop, put the foot down and recover posture. Do not hop indefinitely on one leg or turn a failed sweep into an uncontrolled sideways collision.

05 / KEY POINTS

Four cues with something visible to check

Meet the step; do not chase it

Ask a partner or coach whether contact occurs during travel or after settling. If every attempt is late, shorten the approach or begin the sweep sooner within the same agreed movement. Increasing speed everywhere makes diagnosis harder. Change one timing relationship and compare otherwise similar repetitions.

Move the shoulders as well as the ankle

A displaced foot with an upright, freely turning torso may simply lead to another step. Observe whether the sleeve and lapel connections keep uke’s shoulders involved. The desired result is a coherent loss of support, not a record number of foot touches. Ask uke whether they felt the upper-body direction before the sweep arrived.

Keep your own base underneath you

At the moment of contact, notice whether your chest has tipped beyond the supporting foot. If so, you may be relying on uke to hold you up. Practise touching and returning without finishing. An organised return helps distinguish controlled commitment from a reach that only works when the partner stays still.

Make the contact quiet and comfortable

A loud slap or repeated bruising is feedback about contact and timing, not evidence of a powerful technique. Reduce the pace and confirm the sole position. Comfortable practice allows uke to step naturally, which is essential: a partner anticipating a painful kick will change their gait and remove the situation you are trying to learn.

06 / PROBLEMS & ADJUSTMENTS

Diagnose the missed sweep before adding repetitions

07 / SETUPS & COMBINATIONS

Let the recovery choose the continuation

08 / DEFENCES & COUNTERS

Prevent the timing window and recognise the committed fall

Early prevention includes changing the length or rhythm of the step while keeping posture and grip organisation. Simply lifting the target foot high can offer another attack and may leave you balancing awkwardly. In an introductory defensive drill, use a shorter step or a timely replacement rather than trying to win a hopping contest on one leg.

Tsubame-gaeshi is a recognised counter related to foot sweeping, but it requires its own timing and instruction. Do not treat a desperate return kick as that counter. Have the coach teach the avoidance and returning action cooperatively before adding choice. The learning target is an available movement, not retaliation after painful contact.

Once balance has gone and a controlled fall is developing, use the ukemi your coach has taught. Do not post a locked arm to rescue a missed step. Tori should continue to guide rather than release the sleeve and admire the throw. Agreement about the landing matters especially when practising a sweep whose success can feel unexpectedly sudden.

For the attacker, abandonment is also a defensive skill. If the grip opens, the target stops or your support drifts away, return the sweeping foot and recover stance. Record the reason. An informed reset can prevent a counter and preserve an opportunity to attack again from a better relationship.

09 / GROUND TRANSITIONS

A small sweep can create very different ground tasks

Uke lands on the side near you

Maintain useful sleeve control and identify whether the shoulders can be settled into yoko-shiho-gatame. Move around the legs with posture rather than diving onto the torso. A hand still holding the sleeve does not by itself control the hips; recognise the frames and knees that remain between you.

Uke turns toward the mat

The next task may be a coached turnover rather than an immediate pin. Follow the torso without pulling the neck into a forced twist. If the position becomes unclear, begin the ground drill again from that exact arrival. This separates a useful standing sweep from a ground transition that needs its own instruction.

You finish too far away

Distance after the fall may show that you swept the foot without maintaining upper-body contact. In practice, agree to stop after landing and inspect the gap. Work on controlled connection before asking for a faster pin. Rushing across the gap can hide the reason it appears every time.

A throw-to-ground exercise should also include the case in which no throw occurs. Both partners return to standing rather than automatically falling into a preferred pin. This keeps the standing action honest and makes the continuation a consequence of the actual outcome.

10 / PRACTICE PROGRESSION

Build timing, then add uncertainty

Phase one: feel the step

Use a cooperative partner and small steps. Place light sole contact without completing the throw, then return to stance. Swap roles so each person feels early, useful and late contact under the coach’s supervision. Progress when both partners can describe the difference and contact stays comfortable without exaggerated hopping.

Phase two: connect a controlled finish

Keep the same direction and add the upper-body action and landing. Work in short sets with feedback between them. The partner should fall because the action changes support, not because a fixed repetition count demands it. Progress when tori can remain organised and guide the fall, and uke can receive it confidently.

Phase three: step or stop

Uke chooses one of two agreed movements: the available step or a short stop. Tori attacks only when the sweep fits. Record correct attacks, correct declines and late contacts. This reveals whether the problem is execution or selection. Add variable step length only after this simpler decision is consistent enough for the coach to approve.

Phase four: one continuation

Allow a sweep and one trained follow-up, such as seoi-nage after a forward recovery. Uke may also give no usable response. Keep the reset option throughout. A successful round is one in which the attack matched the movement, even when a better partner defended it. Do not require the same two-technique sequence every time.

Phase five: transfer to ordinary randori

Choose a brief observation goal: identify two genuine sweeping windows, whether or not you score. Afterward, compare your perception with the partner’s feedback or video. If you never obtain a connected grip, use the grip-fighting guide to address that earlier obstacle. More isolated sweeps will not solve an entry you cannot reach.

11 / COMPETITION EXAMPLE

Devitry against Oberan at Tashkent 2023

The IJF day-two technical analysis of Tashkent 2023 reports Agathe Devitry scoring waza-ari against Iva Oberan with a repeated de-ashi-harai action in round two. That is the source-supported example. The report does not establish that your preferred grip or practice rhythm matches the contest action.

For a viewing task, identify the step before the first contact and the recovery before the next. Ask whether the second opportunity was a continuation of the same travel or a new step. These are questions to investigate, not an assertion that every repeated sweep works by the same mechanism. Avoid copying a rapid double action until the first contact is controlled.

Compare the contest with one successful and one failed attempt from your own practice. Look for differences in distance, connection and support transfer, rather than comparing only the speed of the feet. A world-tour example is most useful when it helps you choose a testable question for your next session.

12 / VARIATIONS & COMPARISONS

One travelling foot, two feet, or a planted heel?

Okuri-ashi-harai gathers the feet in a following sweep, often studied through lateral movement. De-ashi-harai focuses on the stepping foot’s opportunity. Do not decide the name only by whether both feet eventually leave the mat; examine what the attacking action actually did to the supports.

Ko-soto-gari directs the opponent backward while reaping from outside near the heel. It is a useful comparison when your attempted moving-foot sweep arrives late. The distinction is practical: timing a mobile foot and removing a rearward support ask different things of the upper body. Learning both does not justify forcing either from a disconnected stance.

Sasae-tsurikomi-ashi uses a supporting block near the ankle while the body is guided around it. In de-ashi-harai the foot is swept away. Practise naming that functional difference before discussing fine variations. A coach can then help you choose the action the position permits, rather than treating every low foot contact as an interchangeable ashi-waza.
