Standard Ko Uchi Gari
Genus小内刈り(Ko Uchi Gari)
TraditionalTranslation: standard minor inner reap
Overview
The Standard Ko Uchi Gari executes the fundamental minor inner reap where the attacker steps inside the opponent's stance, hooks the inside of the opponent's rear heel with the sole of the foot, and reaps it forward while driving the opponent's shoulders backward with hand control. [1] The reaping action lifts the heel off the mat and drives it forward, removing the opponent's rear support while the upper body push ensures backward momentum. [1],[2] The combination produces a sharp backward fall, often landing the opponent directly on their back. [2] The technique is effective from various gripping configurations including collar and sleeve, clinch, and underhook positions. [2],[3]
History & Origin
Effectiveness
Ko uchi gari is one of the most versatile judo techniques because it can be used as a primary attack, a combination starter, or a counter. [1] The minor inner reap targets the opponent's supporting foot from the inside, destabilising their base in a direction that is difficult to anticipate. [1] In MMA, ko uchi gari is frequently used in combination with punches from the clinch. [2]
Lineage
Competition Record
Ko uchi gari is one of the most frequently attempted techniques in international judo competition, used both as a primary attack and as a set-up for major throws such as o uchi gari and uchi mata. [1] In MMA, Karo Parisyan popularised judo trips including ko uchi gari in UFC competition during the mid-2000s. [2]

Biomechanical Mechanism
Primary Action — Chest-to-chest connection with locked hands — body lock controls the opponent's torso as a single unit
Joints Involved — Attacker's hips (lifting or driving), opponent's spine (compressed within the lock), shoulders (restricted)
Force Vector — Varies — front body lock uses lateral or backward arching force; rear body lock uses lift and rotation
Takedown Mechanic — Controlling the torso eliminates independent limb posting — opponent cannot base out effectively
Position & Entry
From collar tie and sleeve/wrist control — Step inside between the opponent's feet, hook or sweep the near leg while pushing with the upper body
From clinch (inside position) — When opponent's weight is on the lead foot, hook it from inside and drive them backward
Variants
Standard trip — blocking or sweeping the support leg while driving the upper body
Combination trip — chaining an inside trip with an outside trip when the opponent adjusts
Counter trip — using the trip as a counter when the opponent attacks
Clinch trip — executing the trip from a tight clinch position

✓Close the distance and push the opponent's upper body backward with your chest and hands to load their rear foot
✓Place the sole of your foot on the inside of their rear heel and reap it forward in a short, quick motion
✓Your body drives forward as the foot reaps — the combined force topples them backward
✓Keep the reap compact; this is a minor technique — efficiency over power
✓The hands push down and back, the foot reaps forward and up — opposing directions
✓Drill as a setup: ko uchi gari to major hip throw, or ko uchi gari to double leg
Common Mistakes
!Reaping with a big, slow wind-up that telegraphs the technique
!Not closing the distance before reaping — the foot can't reach from outside range
!Pushing the opponent's upper body forward (into you) instead of backward (over their heels)
!Reaping the outside of the foot instead of the inside — this is ko uchi (inner), not ko soto (outer)
!Over-committing and falling forward when the reap misses
!Not following up with a secondary attack when the reap partially succeeds
