TraditionalTranslation: body drop
Overview
Tai Otoshi (body drop) is a te-waza technique in which the thrower turns in, extends one leg across and in front of the opponent's lead leg, and pulls the opponent forward and over the outstretched leg using a strong rotational hand action. [1] The extended leg acts as a trip or block — the opponent's lower body is stopped by the leg while the upper body is driven forward by the hands, creating a powerful rotational throw. [1],[2] Despite the prominent role of the extended leg, tai-otoshi is classified as a hand technique because the leg does not actively sweep or lift; all throwing force is generated by the hand action pulling the opponent over the obstacle. [2],[3]
History & Origin
Tai otoshi was included in the original 1895 Kodokan gokyo as a second-set technique and has been one of the most popular and effective competition throws throughout judo history. [1] The technique has been the primary throw of numerous World and Olympic champions, including Toshihiko Koga, who was renowned for his explosive tai-otoshi attacks. [2],[3]

Biomechanical Mechanism
Primary Action — Pulling and lifting with the arms to load the opponent over the shoulder or upper back
Joints Involved — Attacker's shoulders (loading point), elbows (pulling action), hips (turning under the opponent)
Force Vector — Forward and downward rotation — the pulling arm creates circular momentum while the body turns underneath
Kuzushi (Off-balancing) — Forward — breaking the opponent's balance forward over their toes allows the turning entry
Position & Entry
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

FIAS Combat Sambo RulesPDFTraining Notes
✓From grips, step across with the lead foot and turn to face the same direction as the opponent
✓Extend the rear leg across the opponent's lead leg, blocking at shin height with the back of your calf
✓Pull the opponent forward, around, and down with both hands — the sleeve hand (hikite) pulls strongly across your body
✓The opponent rotates over the blocking leg and falls to the mat
✓Your body acts as the axis of rotation, with the leg as the low block that catches their shin
✓Tai otoshi works best when the opponent is moving forward or when you pull them forward with kuzushi
✓The throw should feel like a spinning motion — you rotate and the opponent rotates over you
Common Mistakes
!Blocking with the leg but not pulling with the hands — the hands generate all the throwing force
!Placing the blocking leg after starting the pull — the leg must be in position as the pull begins
!Not extending the blocking leg far enough — it must reach across the opponent's lead shin
!Turning only the upper body and leaving the hips facing the opponent
!Pulling downward instead of forward and across — the pull direction should be rotational
!Leaving the blocking knee bent, which reduces the reach and effectiveness of the block
!Falling backward during the throw instead of staying balanced over the blocking leg

Reverse Tai Otoshi
GenusReverse Tai Otoshi is a variation in which the thrower executes the body drop in the opposite direction from the classical form, reversing the rotation and leg placement to throw the opponent to the other side. [1] This variation is used when the opponent's stance, grip, or movement pattern makes the classical direction unfavourable, allowing the thrower to attack by rotating in the unexpected direction. [1,2] The mechanics remain the same — an extended blocking leg with rotational hand action — but the reversed direction creates a surprise element that catches defenders accustomed to the standard entry.

Standard Tai Otoshi
GenusStandard Tai Otoshi executes the classical body drop where the thrower pivots and turns the back to the opponent, extends one leg across and in front of the opponent's lead shin, and pulls strongly with both hands to rotate the opponent forward and over the blocking leg. [1] The tsurite (lapel hand) lifts and turns while the hikite (sleeve hand) pulls sharply across the body, creating the rotational force that wheels the opponent over. [1,2] The technique requires explosive rotation and precise leg placement to ensure the opponent's momentum carries them over the blocking leg. [2,3]

Frequently Asked Questions
Should I keep my leg straight or bent when doing tai otoshi?
Sampson Judo recommends performing tai otoshi with a bent leg and both toes pointing in the same direction, rather than the conventional flat-footed stance with a straight leg. This bent-leg approach provides advantages and reduces vulnerabilities that can cause injury compared to the straight-leg method.
Why is it important to be up on my toes during tai otoshi?
Being up on your toes prevents knee injury if your opponent resists or applies pressure to your knee—the bent position allows your knee to flex with the movement rather than absorbing direct force. This also gives you flexibility to use your opponent's movement to create the throw.
Where should I place my foot relative to my opponent in tai otoshi?
Your foot should be placed forward on the same line as your opponent's forward motion, not across their body on the same axis. Sampson Judo emphasizes that if both you and your opponent are standing on the same axis, neither has an advantage, so positioning your foot forward gives you better leverage and more options for combinations.
How do I break my opponent's balance in tai otoshi?
Break your opponent's balance in the direction their toes are pointing, using a motion like drawing a sword—pull and cut toward where they're facing. This directional break is critical for a crisp tai otoshi, and then you circulate your body into the throw as your hand directs them around.
