01 / AT A GLANCE
A drop must still produce a throw
Seoi-otoshi is a te-waza, commonly translated as dropping shoulder throw. The IJF definition describes a forward imbalance, a connection onto the back and a descent onto one or both knees that projects uke over the shoulder. The useful distinction is the throwing action. Simply kneeling beneath an opponent does not establish that the technique is working.
Convention: tori is the attacker and uke the partner. The baseline here is a right-sided, sleeve-and-lapel entry: your left hand controls uke’s right sleeve and your right hand holds uke’s left lapel. You turn left into the shoulder relationship and descend in the version your coach teaches. A one-arm grip changes that relationship and must be taught as a specific variation.
“Drop seoi nage” is a common search phrase, but coaches and commentators may use it loosely. Use the official seoi-otoshi name for this dropping action while keeping standing seoi-nage and ippon-seoi-nage available as distinct comparisons. Do not classify a contest from a single frame showing a knee near the mat.
This page is for judoka already practising supervised shoulder throws and ukemi. It is not a suggestion that beginners should bypass a standing entry by dropping lower. The descent creates additional commitments: your support, the partner’s trajectory and your recovery if the throw fails all need attention.

The Kodokan video is the official reference. Efficient Judo supplies an additional demonstration, rather than a complete spoken tutorial. Watch where uke goes during the descent. If you watch only tori’s knees, you miss the connection that distinguishes a throw from an unsupported drop.
On the first pass, identify the grip and whether the demonstrated form uses one or two knees. On the next, follow uke’s shoulder relative to tori’s back. On the final pass, watch the continuation after the body changes level: does the upper-body action keep directing uke over, and where do the partners finish?
Use the player’s pause controls to compare the instant before descent with the position afterward. Avoid treating a still image as a prescribed knee spacing. Partner size, grip and entry affect the shape. Bring a clear observation to your coach: “I lose the sleeve as I descend” is more actionable than “my drop does not look fast enough.”
The reference clips are demonstrations under cooperative conditions. They do not establish a safe drop volume for your knees or prove that a particular grip is allowed in your event. Learn the movement on suitable mats, with a coach controlling progression and a partner prepared for the landing.
03 / WHEN TO USE IT
Descend into a connected opportunity
Uke’s upper body is available forward
An advancing or recovering partner can create a moment when the sleeve and shoulder can be carried into the entry. The drop should be part of that attack, not a rescue after the connection has disappeared. Begin with an agreed forward step so you can recognise the difference between entering with uke and dropping after uke has already stopped.
Uke keeps distance or blocks your turn
Long arms, a stiff frame or a retreat may prevent the shoulder relationship. Dropping from farther away often increases the gap. Work first on grip access and movement. If you cannot bring uke’s upper body into reach during a controlled entry, you have not solved the problem by placing your knees on the mat.
The stance relationship changes
Right-versus-right and right-versus-left grips offer different routes beneath the arms. In the opposite-sided situation, inspect which sleeve you actually control and where the lead arm blocks entry. Rehearse the approach before adding descent. A grip that supports your standing throw may need a different entry angle for the dropping version.
Do not make every stalled exchange into a drop. In practice, include repetitions where you decline the entry and re-establish stance. That preserves a meaningful choice and helps expose whether you are attacking an opening or merely using a familiar action whenever the grip becomes uncomfortable.
04 / HOW IT WORKS
Connect, turn and descend as one action
Prepare the upper-body route
Create forward or front-corner imbalance through the grip and movement. The sleeve hand should guide uke into the intended path while the lapel arm remains in a workable position. A hard initial pull followed by a loose entry allows uke to recover before the drop begins.
Turn into the shoulder relationship
Fit the back and shoulder beneath uke’s upper body as taught by your coach. Keep the lapel wrist and elbow comfortable; do not force a crowded arm into place by dropping your weight through it. If the arm cannot fold into the chosen entry, return to a standing fitting drill and inspect distance and grip height.
Lower your support without leaving uke behind
Seoi-otoshi can use one knee or both knees; choose one version for the drill and record which knee or knees touch. Maintain the sleeve and shoulder connection throughout the descent. The distinguishing question is whether dropping your support and pulling down carry uke into the projection, not whether a knee happens to brush the mat. If uke stays upright at arm’s length, return to a supported fitting exercise. A harder impact on your knees will not repair the gap between your back and uke’s torso.
Continue the projection
The hands and torso must still direct uke over the shoulder. A pause after landing on the knees can leave you underneath a balanced opponent. Practise the complete action slowly enough for the coach to see its continuity, using whatever assisted or reduced-intensity format is appropriate for the pair.
Finish with awareness of the next position
Know whether you remain above, beside or underneath uke. Maintain controlled contact for the landing and prepare to establish a ground position if the exercise continues. Do not drive the head into the mat to force an incomplete action through. The descent is one part of a controlled throw, not permission to sacrifice all posture.
05 / KEY POINTS
Five checks before adding speed
- Connection precedes commitment. In a slow preparation, can your coach see uke’s shoulder coming toward your back before the descent? If not, work on the entry first.
- The sleeve does not stop at knee contact. Follow the sleeve hand in a side-view clip. Check whether its direction continues as your level changes instead of relaxing at the mat.
- The lapel arm remains comfortable. You and uke should report a throwing connection rather than wrist, elbow or shoulder pain. Reset a cramped grip instead of forcing it deeper.
- The drop is controlled. A loud or painful knee impact is not evidence of a powerful technique. Ask your coach to adjust the drill, mats or entry rather than increasing repetitions through discomfort.
- You know your exit. At the end of a controlled attempt, identify who is on top and which side is accessible. An entry that always leaves you unaware of uke’s location needs slower positional work.
Apply these checks in sequence. When the first one fails, polishing the finish may hide the actual problem. Once the connection works, speed can be developed within the conditions your coach sets rather than used to cover a disconnected entry.
06 / PROBLEMS & ADJUSTMENTS
Separate dropping, projecting and recovering
You kneel and uke remains upright
Possible explanations include insufficient forward movement, a gap created during the turn or an entry chosen after uke withdrew. Inspect the frame just before descent. Return to a moving standing fit and change the approach timing. Reintroduce the drop only when the partner actually comes with the entry.
Uke steps around you
The turn may expose your back without drawing uke over the intended shoulder. The sleeve may also become slack at the lowest point. Ask uke to give a small, agreed circling response in a no-throw drill. Check whether the loss occurs before or after the level change, then address that stage specifically.
You stop moving after reaching the knees
You may have learned the drop as the endpoint. Practise a coach-selected assisted finish in which the descent and upper-body direction remain connected. Do not solve the pause by violently pulling a stationary partner over your neck. The adjustment should restore continuity, not add a late jerk.
Your knees become sore during repetitions
Stop the repeated drop and tell the coach. Possible technique, volume and individual health factors need assessment; this article cannot identify the cause. Use an assigned alternative, such as grip-and-entry work without descent, if appropriate. A numerical repetition target is never a reason to continue a painful action.
It scores in drilling but leads to bad ground positions
Cooperative uke may be falling from an incomplete entry. Add a controlled outcome check: after the attempt, freeze only once both partners are safely grounded and identify top position, trapped limbs and available control. Practise the relevant recovery separately instead of assuming a successful demonstration predicts your randori outcome.
07 / SETUPS & COMBINATIONS
Use the drop when the reaction keeps the shoulder available
Ko-uchi-gari to seoi-otoshi
Begin with a genuine ko-uchi-gari attack on an accessible heel. If uke removes that foot and brings the upper body forward into your maintained grip, the recovery may create the dropping shoulder opportunity. Turn and descend only while the connection remains. If uke instead stays vulnerable backward, continue the first attack; if distance opens, reset.
Make uke’s recovery visible in early practice. Later, let uke choose between two responses. Count whether you selected the correct action before counting whether the partner fell. A fast drop into a retreating partner is a poor decision even if they cooperate with the finish.
Standing shoulder entry into a dropping continuation
A standing entry can sometimes become a dropping action while uke remains connected. This is not an instruction to kneel whenever a standing throw fails. The coach must confirm that the shoulder relationship and direction still exist. If uke has moved away or gained control behind you, recover position instead of descending into a worse situation.
Drop attempt into ground control
When uke lands and turns, the next task may be controlling the torso rather than repeating a throw. Agree before the drill whether ground continuation is included. If uke lands on the side with your sleeve control intact, move toward an appropriate pin. If you finish underneath, change the objective to safe recovery. The sequence is defined by the landing, not by the name of the opening attack.
08 / DEFENCES & COUNTERS
Deny the shoulder connection early
For uke, maintain awareness of the controlled sleeve and the approach under your upper body. Early foot movement and posture recovery can remove the entry before tori descends. Work with a coach on moving away from the throwing line without wrenching the sleeve arm or dropping weight onto the attacker’s neck.
Once the throw has committed you to a fall, take the appropriate ukemi. Do not plant a straight arm or try to save the position by landing on the head. In a training round, both partners should know whether the action stops at a failed entry or continues to ne-waza; uncertainty encourages rushed reactions at the most awkward point.
For tori, descending without connection exposes the back and can give uke a route around the shoulders. Practise a failed-entry starting position cooperatively, with uke already in the agreed place, then learn a coach-selected recovery. This is more controllable than asking a partner to unexpectedly block a full-speed drop.
Do not mistake prevention for a late counter. An advanced athlete’s competitive response may involve timing and forces unsuitable for a basic drill. Start with denying the entry, returning to stance or establishing safe ground control, and learn any specific counter as a separate technique.
09 / GROUND TRANSITIONS
Three common ground branches
You land beside uke with control
Use the retained sleeve to stay connected while establishing a base. If the near arm and head are available, kesa-gatame may be appropriate. If the bodies are more square across the torso, work toward yoko-shiho-gatame. The pin must be assembled from the actual position; reaching for a favourite hold without controlling the hips can give uke an escape.
Uke turns onto the front or knees
You have not automatically earned a hold-down. Protect your own balance and work on a coached turnover or control sequence. Avoid hanging on the neck while your lower body is disconnected. The drill can stop at a stable top position if a turnover has not yet been taught.
You remain underneath after the drop
Locate uke’s arms and weight, protect your posture and use the recovery your coach assigns. If you are flattened or your neck is loaded, stop the practice rather than trying to explode out. Rehearse this branch at low intensity so recognising failure becomes part of your technique development.
In your training notes, distinguish “drop lacked connection” from “ground continuation was late.” You can improve one while the other remains weak. Reviewing only the throwing score hides whether the overall exchange left you in a useful position.
10 / PRACTICE PROGRESSION
Earn each increase in complexity
Connection drill
Start with moving entries that stop before descent. Uke follows the intended path and gives feedback on the grip. Progress when the shoulder relationship is consistent and the lapel arm is comfortable. This is a preparation for dropping practice, not a demand to pause during the eventual throw.
Controlled descent and finish
With the coach choosing mats, pace and repetitions, add the taught descent. Keep the partner’s movement predictable. Check whether the hands and torso continue directing uke rather than stopping at the knees. Rest or change tasks before technique quality or comfort deteriorates.
Reaction choice
Use a rearward foot attack followed by either a forward recovery or a longer retreat. Enter only on the response that preserves the shoulder connection. Reset on the other response. The target is recognising a usable opening without relying on a cooperative fall to make every choice appear correct.
Landing and recovery rounds
Begin from safely established post-attempt positions: beside uke, above a turned partner or underneath a defended entry. Allow a small set of coached actions. When these outcomes are manageable, add a ground continuation to controlled throwing practice. Do not introduce all possible counters and submissions at once.
Constrained randori
Include the technique in short rounds with suitable partners and agreed intensity. Log opportunities, attempts and outcomes separately. If you drop repeatedly without moving uke, return to the approach problem rather than increasing aggression. A useful progression produces better choices as well as cleaner successful throws.
If obtaining the starting grip is the limiting step, use the grip-fighting drills guide to work on that approach before increasing throwing repetitions.
11 / COMPETITION EXAMPLE
Abe’s seoi-otoshi attacks at Antalya 2024
The IJF −66 kg report from Antalya 2024 identifies seoi-otoshi in Hifumi Abe’s wins over Samuel Hall and Narmandakh Bayanmunkh. The report names the technique; this article does not assert an independently verified knee arrangement or grip for those attacks.
When studying official footage, compare the last exchange before the entry with the drop itself. What distance did Abe obtain? Did the opponent move forward, remain static or attempt to withdraw? Which hand stayed connected through the descent? Leave an answer blank if the camera does not show it.
A useful follow-up is to compare one scoring attempt with one defended shoulder attack from your own practice. The competition result establishes that the technique can work at that level; it does not explain why your entry failed. Use the IJF seoi-otoshi library for further examples, keeping the report’s named cases separate from any other clip you select.
12 / VARIATIONS & COMPARISONS
A lower entry is not automatically a better entry
Seoi-nage provides the standing sleeve-and-lapel comparison. Ippon-seoi-nage changes the arm connection. Seoi-otoshi concerns the dropping action, which can occur within different grip arrangements. Describe both the grip and action when asking for feedback.
One-knee and two-knee examples are not interchangeable prescriptions. Your coach should decide which version fits the lesson and whether you can control its descent and recovery. Do not choose between them solely because a famous competitor uses one.
A low standing position may still involve a lifting or carrying finish, while a dropping action emphasises descent. Avoid confidently renaming every clip based on knee contact. If classification is uncertain, write what is visible—grip, support and direction—and consult the official references or a qualified coach.
The practical question is which version lets you attack a real opportunity with control. It is reasonable to spend time improving your standing entry even if your eventual competitive preference is a dropping form.
13 / YOUR NEXT PRACTICE
Find the instant where connection disappears
Ask your coach to help compare three slow entries before the descent with a small number of controlled complete throws. Use the same partner and grip. Your question is: “Does uke come with my turn before my knees descend?” Do not test this by dropping faster into a resistant partner.
Record the starting movement, connected entries, complete throws and post-attempt position. Add a short comfort note from both partners. If discomfort appears, stop that task and have the drill changed; do not treat it as another outcome to train through.
Illustrative record: “Six preparation entries had good contact; in four complete attempts, two lost the sleeve during descent. Next session: keep the same approach and work with the coach on continuous hand action.” This separates a descent problem from a grip-access problem and gives the next block a specific purpose.
Use a practice record or Judo AI’s practice tools if helpful. At the next review, ask whether the observed change carried into moving practice. A better-looking isolated drop is useful progress, but it is not yet evidence of better decisions in randori.
