Modified Kata Guruma
Genus肩車(Kata Guruma)
TraditionalTranslation: shoulder wheel
Overview
Modified Kata Guruma encompasses variations of the shoulder wheel that use alternative grips, entries, or body positions to achieve the cross-shoulder loading without the traditional leg grip. [1] These modifications include using belt grips, gi tail grips, over-the-back grips, or underhook configurations to secure the opponent across the shoulders without directly grabbing the legs. [1],[2] Modified kata-guruma techniques were developed primarily in response to competition rule changes and represent the ongoing evolution of traditional techniques under modern rulesets. [2],[3]
History & Origin
Modified kata guruma variants proliferated after the 2010 IJF rule changes, as judo competitors and coaches found creative ways to preserve the shoulder wheel mechanic without using direct leg grabs. [1] These modifications demonstrate the adaptability of judo technique to evolving competitive requirements. [2],[3]
Effectiveness
The modified kata guruma adapts the shoulder wheel for post-2010 IJF rules, using drop entries or modified grips to achieve the same effect without a direct leg grab. [1]
Lineage
Modified kata guruma variations emerged after the IJF's 2010 leg-grab prohibition, representing competitive adaptations that maintain the shoulder-wheel mechanics while complying with current rules. [1]
Competition Record
Modified kata guruma variants are scored in IJF competition under current rules. [1]

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 collar and sleeve grip — Pull the opponent forward and up, turn in while dropping below their centre of gravity, load them onto the back/shoulder and rotate forward to throw
From sleeve grip (ippon seoi) — Secure the sleeve, step across, load the arm over the shoulder while turning, pull and throw
From underhook — Turn in with the underhook side, load the opponent over the shoulder and drive forward
Variants
Morote seoi nage — two-handed shoulder throw with both hands gripping
Ippon seoi nage — one-arm shoulder throw loading the arm over the shoulder
Drop seoi nage — dropping to the knees for a lower entry point
Korean-style shoulder throw — modified entry with deeper level change

✓Modified kata guruma adapts the shoulder wheel for rulesets that prohibit leg grabs (current IJF rules)
✓Instead of gripping between the legs, use modified grips: deep lapel grip, belt grip, or arm-only control
✓The entry still requires getting under the opponent's centre of gravity — the grip modification does not change the body mechanics
✓Common modifications: grip the belt or back of the gi instead of the legs; use a deep underhook; wheel using sleeve and collar
✓The modified version can also be performed as a Georgian-style belt grip kata guruma
✓The key adaptation: the arm that would have grabbed the legs instead grabs the belt, back of the gi, or wraps around the body
✓In freestyle wrestling and no-gi grappling, the traditional leg-grab version remains legal
Common Mistakes
!Using the traditional leg-grab entry in IJF judo competition — this results in a penalty
!Not adapting the grip strategy for the specific ruleset
!Attempting the modified version without a secure alternative grip — the belt or gi-back grip must be firm
!Not getting low enough — the modified grips require an even lower entry because the leverage is reduced
!Trying to wheel without adequate grip — if the alternative grip fails, you end up under the opponent with no throw
!Not drilling the specific modified entry — treating it as identical to the traditional version leads to failure
!Forgetting that the fundamental mechanics (duck, load, wheel) remain the same — only the grip changes

Frequently Asked Questions
What posture should I maintain when dropping under for Kata Guruma?
You want to posture up with the back of your neck positioned right into your opponent's armpit, rather than bending your back forward. Dropping with poor posture makes it difficult to maintain tension and gives your opponent an easier opportunity to stand up and escape.
How do I control my opponent's arm during the setup?
Grip at the collar and sleeve, then push the sleeve across your partner's body while tapping the seam on the back of the shoulder. This tight control down that side of their body prevents them from simply dropping and turning to escape.
How can I use my elbow to help complete the throw?
Position your elbow on the inside of your opponent's thigh, which allows you to use it as a lever point to tip them over during the execution of the technique.
