Tomoe NageHow it works and how to improve it

01 / AT A GLANCE

The sacrifice must move a connected opponent

Tomoe-nage is the circular throw, classified as ma-sutemi-waza. Tori gives up the standing position while maintaining a connection that carries uke forward, using a sole placed at the lower abdomen to support and guide the projection. Sitting down is only one part of the action. If the opponent’s balance and torso remain behind, the sacrifice may simply put you underneath a stable partner.

Convention: you are tori and the receiver is uke. The reference here uses your left hand on uke’s right sleeve, your right hand on uke’s left lapel and your right sole at uke’s lower abdomen. Your left leg helps organise the approach and descent. This is a basic forward version; a side-directed yoko-tomoe entry needs its own coached body orientation and landing path.

Tomoe nage and tomoenage are alternate search spellings. Yoko-tomoe-nage is a commonly used variation name, not an additional item in the official 100-technique list. Keep the official classification separate from practical descriptions of direction. A side entry is not simply the basic version performed while twisting unpredictably after you have already fallen.

Learn the descent and receiving action under supervision before full projection. The partner needs appropriate ukemi, and the attacker needs a controlled route to the mat. Do not jump onto the opponent, kick the abdomen or use a desperate backward fall to escape an uncomfortable grip. A successful learning repetition should remain manageable for both people.

02 / WATCH THE TECHNIQUE

Watch the hips approach before the supporting foot extends

The Kodokan demonstration provides the formal reference. Efficient Judo’s second video is a demonstration, not a complete spoken instructional series. First watch how the standing distance changes. Then identify the sole contact and the movement of uke’s shoulders. Finally observe the attacker’s descent and the receiver’s path over the body.

In your own video, look at the gap between the hips as you begin to sit. If the gap grows while your arms stretch, the partner may never be carried into the projection. A strong leg extension cannot reliably repair that separation. Ask a coach to compare the approach in one connected attempt and one in which uke remains standing over you.

Watch whether the supporting sole stays in a deliberate contact or slides because the leg is already nearly straight. The starting distance and knee position affect the available guiding action. Do not infer that a harder push is needed merely because the foot slips. Inspect the placement and connection before adding force.

Also watch the end of the movement. Does tori follow into a top position, remain underneath with a useful connection, or lose contact entirely? Those outcomes require different ground decisions. A highlight ending at the score can hide the recovery work that matters in your own training when the throw does not finish cleanly.

03 / WHEN TO USE IT

Use forward commitment, not an empty backward drop

A connected forward-moving opponent

A partner advancing into your grips can provide the first learning situation. You still need to organise the shoulders and distance so the descent carries them forward. Forward walking alone does not guarantee kuzushi. If the arms remain long and the torso stays behind the feet, dropping underneath may leave you carrying none of the opponent’s movement.

A rearward threat creates a forward response

A ko-uchi-gari or o-uchi threat may provoke forward recovery. Tomoe becomes an option only if the grip and distance support a genuine projection. Do not use every failed foot attack as a signal to sit down. Recover the facing relationship and identify the response before choosing the sacrifice.

An opponent resisting an upward or forward connection

Some gripping exchanges create a useful reaction, but the details depend on the grip and stance. Have the coach select the setup. Repeatedly pulling and then dropping without moving uke’s support teaches a habit of sacrificing position rather than a throwing opportunity. Your partner should sometimes resist in a way that makes the attack unavailable.

When the body remains distant or the grip is lost

A retreating partner, a slipping sleeve or a blocked foot-placement route can remove the opening. Stay standing and rebuild. The fact that you can reach the abdomen with a long leg does not mean you can project the body. Distinguish physical contact from a connected entry that leaves a controlled path for both participants.

04 / HOW IT WORKS

Coordinate the descent, contact and forward arc

Bring the torso into the attack

Use the sleeve and lapel relationship with your movement to organise uke forward or toward a front corner. The partner should travel with the connection rather than remain upright while your jacket grips stretch. Practise this relationship without dropping first. It helps you recognise whether the sacrifice will carry a body or merely release your own support.

Close the distance for the descent

Your hips need to descend in a position that preserves the upper-body connection. Sitting too far away leaves a long gap and may straighten the supporting leg before it can guide the throw. Crowding without room for the sole is a different error. Work with the coach to find an approach appropriate to the pair rather than copying a fixed step length.

Place the sole deliberately

The reference uses the right sole at the lower abdomen. Establish a comfortable placement without a kick, avoiding the groin and any uncontrolled impact. The foot supports and guides a connected body; it is not a strike. If the contact slides or causes discomfort, stop and correct the placement before adding the full descent.

Descend and guide the arc together

The fall backward and the hand action should bring uke over while the supporting leg contributes to the projection. Avoid a sequence of sit, stop, then push harder with the foot. That pause often leaves the partner stable above you. Keep the movement continuous at a pace where the receiving partner can perform the agreed ukemi.

Finish with a positional intention

A controlled projection may allow you to follow the rotation and come above uke. It may also leave a different ground relationship. Learn the follow-through under instruction rather than rolling blindly after every attempt. The initial priority is a safe landing; the next is recognising whether you have top control, a guarded bottom position or a disconnected scramble.

05 / KEY POINTS

Four checks before increasing commitment

The partner comes with the descent

Ask a coach whether uke’s shoulders move forward as you lower, or whether you drop away while they remain over their own feet. A useful entry preserves the connection. Test a smaller approach and descent before increasing speed. The amount of your backward movement is not a measure of how much kuzushi you created.

The foot has room to guide

If the right leg is already fully stretched at contact, inspect the distance. If the knee is crowded against the torso with no route for the foot, inspect it in the other direction. Use a cooperative placement to distinguish those errors. Both can cause a stalled throw but should not receive the same correction.

The hands maintain a clear route

The sleeve connection helps guide the receiver rather than leaving an arm free to post unpredictably. Avoid wrenching the shoulder or dragging the head toward the mat. The coach should inspect how the hand direction cooperates with the foot and descent. A controlled arc is the objective, not an isolated upward leg press.

You know what happens if the projection stops

Before adding resistance, agree a safe failed-attempt position and recovery. Tori should not panic when uke remains above, and uke should not leap onto a partly extended leg. This preparation makes it possible to practise honest resistance without pretending every sacrifice throw must succeed.

06 / PROBLEMS & ADJUSTMENTS

Separate a missing entry from a weak finish

07 / SETUPS & COMBINATIONS

The first attack should create a usable response

08 / DEFENCES & COUNTERS

Keep the body behind its support early

Early prevention involves recognising the forward connection and adjusting posture or distance before the attacker descends into a useful relationship. The exact response depends on the grips. Practise a small, agreed defensive step while the attacker is still able to reset. Do not begin by improvising a late leap around a partner already underneath you.

If the throw is committed, receive it with the ukemi taught for the situation rather than posting a straight arm or driving the head toward the mat. Tori should preserve a controlled path and stop if the contact or grip becomes unsafe. The receiving action deserves explicit instruction; it should not be left for the partner to discover during a full-speed attempt.

When an attack fails and you remain above, first establish a balanced ground position. Do not jump onto the attacker’s abdomen or wrench a leg aside. Your coach can teach an appropriate pass or pin from the particular arrival. Staying on top is useful only if you can control the next movement without exposing either person to an uncontrolled landing.

For the attacker, a failed attempt requires immediate recognition of bottom position. Protect your posture and use the ground recovery taught for that relationship. Reaching desperately for another throw while flat underneath a stable opponent can delay the defensive task you actually need to perform.

09 / GROUND TRANSITIONS

Plan for three outcomes, not one highlight finish

The projection carries you to the top

If the follow-through is controlled, settle your base and identify uke’s frames before pursuing a hold. A tate-shiho or side-control destination depends on where you arrive. Do not assume mount merely because you rolled after the throw. Check whether the knees or a trapped leg still interrupt the position.

Uke lands on the side while you remain connected

You may be able to turn above or move around the legs, but the exact route needs coaching. Pause from that landing in early practice. Identify which arm is controlled and where the hips can move. A stable positional transition is more useful than a rushed attempt to reproduce a competitor’s submission sequence.

Uke stays above you

Recognise a bottom recovery task. Maintain useful frames and leg positioning as taught by your coach, and work toward a defensible position. Do not continue pressing with the original supporting foot if it is no longer controlling the body. The throw has ended; the ground exchange now has different objectives.

Submissions such as juji-gatame appear in high-level tomoe systems, but they require separate instruction and applicable age and event rules. This guide does not give a shortcut to an armlock. Build control and clear communication first, and release immediately when the partner taps or asks to stop.

10 / PRACTICE PROGRESSION

Make the failed attempt safe before making the entry unpredictable

Contact and receiving preparation

With a qualified coach, establish the foot placement, grip and intended fall. Rehearse only the components the coach selects. Both partners should understand the receiving route and the stop signal. Progress when the sole contact is comfortable and the descent can be controlled without a jump or a sudden backward collapse.

Cooperative connected projection

Use a small, agreed forward movement and complete the throw. Keep the set short enough to inspect distance. Progress when uke is carried through the connection and tori can guide the landing. If the receiver has to vault voluntarily to make the technique work, revisit the approach rather than rewarding the appearance of success.

Controlled failed-entry position

Let the coach introduce a modest defence that stops the projection safely. Begin the recovery from that position at low intensity. Tori learns to recognise bottom position; uke learns to stabilise rather than leap around the legs. This makes later resistance informative instead of turning each miss into an uncontrolled scramble.

Forward response or retreat

Uke chooses between an available forward movement and a retreat that removes the opening. Tori throws or stays standing. Record correct declines and disconnected sacrifices separately. Add a setup attack only when that basic selection is clear. More combinations will not solve a habit of dropping regardless of the opponent’s movement.

Join the throw to one ground objective

Choose either a controlled top arrival or a specific bottom recovery, depending on the outcome. Work on one at a time, then allow both. In ordinary randori, review not only whether tomoe scored but where you ended up afterward. That record reveals whether the next priority is the entry, the follow-through or defensive groundwork.

11 / COMPETITION EXAMPLE

Tsunoda against Boukli at the Paris Olympics

The IJF preliminary-round report from Paris 2024 describes Natsumi Tsunoda throwing Shirine Boukli for ippon with tomoe-nage in their −48 kg contest. It provides a named competition example. The report alone does not justify copying an exact foot placement or assigning a timestamp to the action.

A second IJF report from Tokyo Grand Slam 2023 describes Tsunoda’s tomoe-nage-to-juji-gatame transitions against Baasankhuu Bavuudorj and Tara Babulfath. This supports studying the relationship between a throwing threat and groundwork, while keeping the submission as a separately coached skill.

For viewing, compare when the forward connection is established and what remains controlled after the projection. These are questions, not an assertion that the same entry produced every result. Your practical takeaway should be a testable observation about connection or ground arrival, rather than an attempt to reproduce an elite athlete’s whole system immediately.

12 / VARIATIONS & COMPARISONS

Tomoe-nage, side entries and sumi-gaeshi

Sumi-gaeshi uses an instep connection beneath or behind the opponent’s leg in its formal reference, rather than the sole at the lower abdomen used here. Both involve sacrificing standing position, but the contact and supporting relationship differ. Do not transfer a foot-placement instruction from one to the other without checking the technique.

Yoko-tomoe-nage describes a side-directed variation of tomoe-nage. The changed angle affects the descent, hand direction, available landing and follow-through. Learn those relationships as a coherent version. Merely falling sideways after an unsuccessful forward attempt is not a reliable variation.

An unsuccessful sacrifice may resemble pulling a partner into groundwork, but that resemblance does not establish a valid throwing action or its treatment under current competition rules. This is a technical study guide rather than a refereeing manual. Check the applicable rules with a qualified coach or referee before using a variation in shiai.
