The Major Inner Reap family covers ashi-waza techniques in which the thrower reaps the opponent's leg from the inside, driving the attacking leg between the opponent's legs to sweep away the supporting foot or leg. [1] Inner reaping techniques (uchi-gari) attack the opponent's base from the inside line, which is often less well defended than the outside, creating powerful close-range throws that are difficult to counter. [1],[2] The two primary techniques — o-uchi-gari (major inner reap) and ko-uchi-gari (minor inner reap) — attack different legs and at different ranges, forming one of the most important attacking combinations in judo. [2],[3]
История и происхождение
Inner reaping techniques were part of the original Kodokan gokyo and have been central to judo's tactical framework since the art's founding. [1] The o-uchi-gari/ko-uchi-gari combination was systematised as one of judo's fundamental renzoku-waza (combination technique) patterns, taught as complementary attacks that set each other up. [2],[3]

Биомеханический механизм
Primary Action — Sweeping, reaping, or blocking the opponent's foot or leg to remove their base of support
Joints Involved — Attacker's sweeping leg (ankle or shin contact), opponent's supporting ankle or knee (swept)
Force Vector — Two opposing forces — the upper body is directed one way while the sweeping leg removes the support in the opposite direction
Timing Principle — Maximum effectiveness when the opponent's weight is committed to the targeted foot — timing supersedes strength
Позиция и вход
From judo grip — Use push-pull timing (kuzushi) to catch the opponent as they step, sweep the support foot in the direction of their movement
From clinch (collar tie) — Push or pull to make the opponent step, sweep the stepping foot at the exact moment it lifts off the mat

✓Inner reaping throws attack the opponent's leg from the inside — your leg sweeps or reaps their leg inward toward their centre line
✓Inner reaps destabilise the opponent's base by taking out the leg that is carrying their weight from the inside
✓O uchi gari (major inner reap) and ko uchi gari (minor inner reap) are the two primary techniques
✓These throws work best when the opponent is standing with a wide base or weight shifted to one leg
✓Inner reaps are excellent combination tools: they pair naturally with outer reaps, hip throws, and shoulder throws
✓Set up inner reaps by pushing the opponent backward to make them brace, then reap the bracing leg
✓Inner reaps are high-percentage techniques at all levels of judo competition
Типичные ошибки
!Reaping the unweighted leg — the reap must target the leg that is bearing the opponent's weight
!Not driving the opponent's upper body in the direction of the reap — the hands must push or pull to create the off-balance
!Reaping too high on the leg — target the ankle or lower calf for the best leverage
!Standing too far away and reaching with the reaping leg — close the distance first
!Not committing the upper body to the throw direction — the reap alone is insufficient
!Attempting inner reaps against an opponent with a narrow stance — wider stances are more vulnerable
!Using the instep instead of the back of the calf or sole for the reaping action

Ko Uchi Gari
ПодсемействоKo Uchi Gari (minor inner reap) is a judo ashi-waza technique in which the thrower reaps the opponent's near leg from the inside, using a small, quick hooking or sweeping action against the inner ankle to remove the support. [1] The 'ko' (minor) designation reflects the smaller range and closer distance compared to o-uchi-gari — ko-uchi-gari targets the near foot with a short, sharp reap rather than reaching for the far leg. [1,2] The throw is typically performed as a quick snapping attack when the opponent's weight settles on the near foot, and it is one of the most effective setup techniques in judo for chaining into larger throws like o-uchi-gari, uchi-mata, or seoi-nage. [2,3]

O Uchi Gari
ПодсемействоO Uchi Gari (major inner reap) is a judo ashi-waza technique in which the thrower drives the leg between the opponent's legs and reaps the far leg from the inside, sweeping it backward while pushing the opponent's upper body in the same rearward direction. [1] The 'o' (major) designation indicates that the technique targets the far leg with a large, powerful reaping action, creating a diagonal throwing line. [1,2] The thrower typically steps deep between the opponent's feet, hooks or reaps the far leg's inner calf or ankle with the foot or shin, and drives forward to topple the opponent backward over the reaped leg.

Часто задаваемые вопросы
What's the starting position for the major inner reap?
You need a solid underhook and overhook with good arm control, similar to pummeling position. According to CORE MMA, make sure you have nice and tight control in the arm with a good underhook before attempting the technique.
How should I angle my body when setting up the major inner reap?
Step off at about a 45-degree angle, with your back leg stepping and lead leg pulling to straddle your opponent's lead leg. CORE MMA emphasizes that this angled positioning allows you to use your leg to trip theirs.
Where exactly should I target when executing the reap?
Trip at the ankle level, not higher up the leg. CORE MMA explains that you want the same catching action that occurs when you trip on a sidewalk—the contact at the ankle causes the body to commit forward over the top.
What should I do as they start to drop to avoid getting swept?
Step over the knee to secure at least half guard rather than allowing them to re-guard or sweep you. CORE MMA stresses the importance of stepping over the knee during the follow-through to maintain control.
