Standard Tani Otoshi is the classical valley drop in which tori, from a standard gripping position, slides to one side, extends one leg behind uke's legs to form a barrier, and drops their body weight laterally while pulling uke backward over the outstretched leg. [1],[2] Uke falls backward over the combined obstacle of tori's leg and body, typically scoring ippon when executed with sufficient control and force. [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 — Break opponent's balance in the intended direction, place foot on their hip or thigh, fall backward while pulling them over
From clinch — During a grip exchange, sacrifice balance by falling deliberately while using body weight to project the opponent
Варианты
Rear sacrifice — falling backward while pulling the opponent over
Side sacrifice — falling to the side to project the opponent laterally
Rolling sacrifice — combining a roll with the sacrifice throw for rotation
Counter sacrifice — using the opponent's forward pressure as the driving force

Tani otoshi is a yoko sutemi waza (side sacrifice throw) in which the thrower abandons their upright position and drops to the ground, using gravity rather than muscular force to execute the technique. According to Shintaro Higashi, it is among the most dangerous throws in judo, comparable only to kani basami, because the thrower's weight drops uncontrollably onto the opponent's leg, risking ACL tears and other serious ligament damage regardless of the thrower's technical proficiency. Efficient Judo emphasizes that proper kuzushi (balance breaking) must occur backwards over the opponent's heels, with the thrower's head positioned in front of the opponent's chest to facilitate this break; common errors include insufficient kuzushi followed by lunging onto the nearest leg. Riki Judo Dojo stresses perpendicular body positioning, precise footwork (the blocking leg traveling behind the far heel), and proper hand mechanics—the pulling hand (hikite) breaks balance while the following hand (tsurite) controls—with the thrower looking straight ahead through the throw. All three instructors agree on the paramount importance of proper setup and timing, with Higashi and Efficient Judo detailing multiple variations and counters (including switches from failed turn throws and responses to opponent attacks), while Riki Judo Dojo emphasizes waza judo (technique-based execution) over muscular force. The instructors collectively stress that this throw requires careful, controlled practice and carries inherent risk.

✓As uke turns in for a forward throw (or pushes into you), step your near foot behind both of uke's feet
✓Extend the leg to create a low barrier behind their legs
✓Sit down to the side of uke while pulling them backward with both hands — lapel pulls them over the leg, sleeve directs the fall
✓Your sitting direction should be roughly 45° to uke's rear — not straight behind them
✓Keep pulling throughout the entire drop — don't release when you sit
✓Land on your side or buttock, not on uke's legs — control the landing
✓Immediately transition to a pin or top position — tani otoshi often gives you a kesa gatame opportunity
Типичные ошибки
!Not stepping deep enough behind uke — your leg must be behind both their feet
!Sitting down directly behind uke instead of to the side — you get trapped under them
!Releasing the grips when sitting — maintain tension to pull uke over the leg
!Extending the blocking leg but not sitting — just the leg alone won't throw them
!Attempting against an opponent moving backward — tani otoshi requires uke to be moving forward or stationary
!Not pulling uke's upper body while sitting — both the sit and the pull must happen together
!Forgetting to transition to groundwork — you end up seated with no follow-through

Часто задаваемые вопросы
When should I attempt Tani Otoshi instead of a turn throw?
According to Shintaro Higashi, Tani Otoshi is the right choice when your opponent closes off the space by turning their hips and bringing their knees in front to defend against a turn throw to your dominant side. This defensive positioning makes turn throws very difficult, creating the ideal moment to go for Tani Otoshi.
What's the most common dangerous mistake beginners make with Tani Otoshi?
Efficient Judo emphasizes that beginners often fail to completely break their opponent's balance backwards before lunging onto the closest leg, which leads to sitting on the knee and bending it sideways—risking serious ligament damage. Proper kuzushi (balance breaking) is essential for safety.
How should my body position during the entry to Tani Otoshi?
Riki Judo Dojo stresses that you must sit down (not back), keep your right knee bent as your leg travels across to go behind the opponent's heel, stay on the ball of your foot to allow proper bending, and position your head in front of the opponent's chest for balance breaking. Make sure to step past the opponent's toes or heel to reach properly.
How does timing factor into Tani Otoshi as a counter?
Efficient Judo explains that when used as a timing technique, Tani Otoshi works best after your opponent attacks with a hip throw: first fully block their attack, wait for them to recover their balance, then immediately break their balance and execute the throw.
