Uchi Mata

Last updated: June 13, 2026

What is uchi mata?

Uchi mata is one of the original 40 throws of judo, developed by the sport’s founder, Jigoro Kano, and it remains part of the Kodokan’s current list of 67 recognised throws. In the 1920 Gokyo no waza, judo’s standard teaching syllabus, it sits in the second group, Dai Nikyo. The Kodokan classifies it as ashi-waza, a foot and leg technique, even though the hips do much of the lifting, which is why some older texts group it with hip throws.

The appeal comes down to how often it works. Across decades of competition, it has been one of the highest-scoring techniques in the sport, and elite judoka build entire games around it. A reader is most likely to hear the term during judo broadcasts, but it also turns up in Brazilian jiu-jitsu and mixed martial arts, where grapplers borrow it for takedowns. Students usually meet it at the upper kyu grades, around 2nd and 1st kyu (blue and brown belt), since it rewards timing and balance over raw strength.

How uchi mata works

The throw begins with the thrower breaking the opponent’s balance forward, drawing them onto the balls of their feet. From there, the thrower turns in and drives one leg backward and upward between the opponent’s legs, catching the inside of the thigh and lifting it like a lever while the arms pull the upper body forward and down. The opponent rotates over the hip and lands on their back.

What separates uchi mata from a true hip throw is the angle of entry. Rather than turning all the way around so the back faces the opponent, the thrower stays at roughly a forward-facing diagonal, which leaves a gap for the leg to slip between the opponent’s legs instead of sweeping across the front of both thighs. Contact lands high on the inner thigh, not at the knee, where the lift has far less effect and can even be illegal under competition rules.

Several variations exist. A ken-ken uchi mata has the thrower hop on the supporting leg to chase a retreating opponent, while a drop version takes the body low to the mat for extra commitment, a form seen often in elite competition.

Uchi mata vs harai goshi

Newcomers mix up uchi mata and harai goshi constantly. The grips, the forward off-balance, and the spinning entry look nearly identical at a glance, so the confusion is fair. What sets them apart is one thing: where the leg lands.

Feature	Uchi mata	Harai goshi
Meaning	Inner thigh throw	Sweeping hip throw
Leg contact	Between the opponent’s legs, against the inner thigh	Across the outside of the near thigh and hip
Entry	Forward-angled, partial turn	Fuller hip turn, back to the opponent
Classification	Ashi-waza (foot and leg technique)	Koshi-waza (hip technique)

Uchi mata drives the sweeping leg between the opponent’s legs to lift the inner thigh. Harai goshi instead sweeps across the outside of the near thigh and hip, which is why it counts as a hip technique, while uchi mata counts as a leg technique. Judoka exploit the overlap, faking one to set up the other.

Uchi mata in MMA and BJJ

Because uchi mata is a gi-dependent throw in its classic form, it does not appear in mixed martial arts as often as wrestling takedowns do. The grips change without a jacket to pull on, and Bloody Elbow has noted that the throw demands enough dedicated practice that many fighters never fully add it to their game. Fighters with a judo base are the exception.

Karo Parisyan, an Armenian-American judoka who fought in the UFC, built much of his takedown game around uchi mata and is often named among its best practitioners in the cage. Ronda Rousey, an Olympic judo bronze medallist before her MMA career, also relied on the throw and its counter during her run as UFC champion. In the cage, the setup usually comes from the clinch, often off an underhook or a whizzer, or as a counter when an opponent shoots in for a single-leg and leaves their hips exposed.

Counters to uchi mata

Like any committed forward throw, uchi mata leaves openings if it is timed poorly or entered before the opponent’s balance is broken. The most distinctive answer is uchi mata sukashi, the “inner thigh void,” where the defender slips aside so the sweeping leg catches nothing, then sends the attacker tumbling forward in the direction they were already heading. The Kodokan recognises it among its newer accepted techniques.

Two other common responses are uchi mata gaeshi, which intercepts and re-throws the sweeping leg, and tani otoshi, a valley drop that blocks the entry and drops the attacker backward. Te guruma, a lifting counter, also works against a poorly committed attempt.

Frequently Asked Questions

What does uchi mata mean?

It translates from Japanese as “inner thigh throw,” describing where the sweeping leg makes contact: the inside of the opponent’s thigh.

Is uchi mata a hip throw or a leg throw?

The Kodokan classifies it as ashi-waza, a foot and leg technique, even though the hips do much of the lifting. Some older judo texts group it with hip throws for that reason.

What belt do you learn uchi mata at?

It is usually introduced at the upper kyu grades, from 2nd kyu (blue belt) through 1st kyu (brown belt). JudoLearn notes it relies on timing and balance rather than strength, which is why it comes later in the syllabus.

Why is uchi mata so common in competition?

It works from almost any grip and on either side, and it flows naturally out of other attacks, so a skilled judoka can keep threatening it throughout a match.

Is uchi mata legal in BJJ and MMA?

Yes. It is a legal takedown in both, though the grips and entries are adjusted when there is no gi to hold.
