The uchimata (inner thigh throw) is one of Judo’s most iconic and devastating techniques, captivating practitioners with its blend of timing, balance, and dynamic movement. Recently, I explored three instructive videos, each offering a unique take on the mechanics and strategies behind this throw. Here, I’ll break down the essence of uchimata as presented in each, so you can discover which approach best fits your style or level.

1. Uchimata in Kenkayutsu – Attacking the Front Leg
The first video focuses on executing uchimata from a kenkayutsu (cross stance) position, targeting the opponent’s front leg—a common obstacle in classical uchimata. This version is particularly accessible for those who may not possess explosive leg strength, as it splits the throw into two distinct stages:
- Stage One: The tori (thrower) uses their foot to disrupt the opponent’s balance, focusing on placing the back of the knee against the opponent’s kneecap. The goal is to coax the front leg backward, opening a path for the throw.
- Stage Two: The tori rotates their foot and sweeps, again with the back of the knee connecting to the target leg, this time swinging the leg sideways rather than lifting high. The hands—one twisting and pulling, the other lifting—work in harmony to control the opponent’s upper body.
This approach demystifies uchimata for those who struggle with the “big lift,” emphasising angles, off-balancing, and directional force over raw power.
2. Seminar with Sensei – World and Olympic Champion Uchimata
The second video documents a seminar led by a renowned Japanese sensei—World and Olympic Champion—who delves deeply into uchimata’s precision and adaptability.
He underscores several key points:
- Arm and Grip Action: The sweep hand twists up and towards the shoulder, fingers leading, while the other hand draws the opponent’s body close to you, maximising control and kuzushi (off-balance).
- Entry & Footwork: The tori drops their centre of gravity and steps in deeply, keeping the body upright and knees bent. The supporting foot rotates under the opponent, and entry is both quick and precise.
- Execution: The tori elevates the opponent’s body with the lifting leg while keeping the upper body straight, then rotates sharply, guiding the opponent down and through the mat.
- Adaptations: Against stronger or resistant opponents, he demonstrates a spinning uchimata, breaking the grip and throwing with a circular motion. He details different approaches for left-handed opponents (two-step version) and shares practical tips for adjusting grip and entry based on size or resistance.
His demonstration is a masterclass in fundamentals and subtle adjustments, stressing the importance of bringing the opponent close and maintaining strong body posture throughout the throw.
Interestingly, his leg action is closer to Hani Goshi than Uchi mata, thus suggesting that this is more a very effective Hani Goshi. But there is no reason to think that the leg action could not be more on the opposite leg and still be just as effective as Uchi Mata.
3. "Nukimatan" – A Rear Uchimata Variation
The third video presents a succinct, advanced variation called "抜きまたん" (Nukimatan). Here, the tori:
- Engages directly, stepping in head-on.
- Executes a rear uchimata by lifting up the opponent’s inner thigh from behind.
- Finishes by pulling them down, illustrating how the technique can be effective from a close engagement, using leverage and direction rather than a dramatic lift.
This streamlined version of uchimata is especially effective for close quarters or when direct engagement is required. The key is sharply lifting the inner thigh, then using gravity and grip to pull the opponent toward the mat.
Conclusion: Different Roads to the Same Throw
Each of these videos highlights a different entry, grip, or strategic focus, yet all share the fundamental principles of uchimata: creating off-balance, entering deeply, and redirecting the opponent’s energy. Whether you prefer a front-leg attack from cross stance, the classic championship style emphasising posture and grip, or an advanced rear variation, mastering the details of uchimata will not only boost your technical repertoire but deepen your understanding of Judo's dynamic nature.
