You have the leg, you start to lift, and your opponent feels nailed to the floor. Or you get the person onto your shoulders and are immediately pressed into an unstable stance. That is the classic sticking point of Kata Guruma (shoulder wheel). It is a hand throw from the third group of the Kodokan Gokyo, known in wrestling and BJJ as the fireman's carry. This guide covers its classification and numbering, the carry mechanics, entry timing, general defensive ideas, and where the throw stands now that competitive judo bans leg grabs.
1. Origin and Story: The Last Throw of Kodokan Group Three
Kata Guruma has no verifiable single "inventing match," so the first half of this section only states classification facts that were cross-checked. The Wikipedia entry says it is one of the traditional 40 Kodokan throws, developed by Kano Jigoro, belongs to the third group (Dai Sankyo) of the Gokyo no Waza, is one of the current 67 Kodokan throws, and is classed as a hand technique (te-waza), meaning a throw driven mainly by the arms pulling and carrying. Wikipedia's Judo entry records that Kano opened his school at Eisho-ji temple in Tokyo in February 1882, which is now regarded as the founding of the Kodokan.
The numbering can be matched across two sources. Wikipedia's Gokyo no waza entry lists Kata-guruma as the 8th and last of the 8 throws in the third group, alongside Kosoto gake, Tsuri goshi, Yoko otoshi, Ashi guruma, Hane goshi, Harai tsurikomi ashi and Tomoe nage. Judo Info numbers it 24th of the 40 throws overall and states that the syllabus originated in 1895 at the Kodokan in Tokyo and, from 1920 to 1982, consisted of 40 throws in 5 groups. With 8 throws per group, the 8th throw of group three is indeed number 24 overall, so the two sources agree.
The Name and Its Link to the Fireman's Carry
The Japanese characters (肩車) literally mean "wheel on the shoulders," usually rendered as shoulder wheel. The wrestling name fireman's carry comes from the move's resemblance to the way firefighters carry an injured person, as described in Wikipedia's Takedown (grappling) entry. KokaKids' judo instruction also calls it a fireman lift.
Kyutaro Kanda: The Judoka Who Specialized in Kata Guruma
The name most often tied to the throw in judo history is Kyutaro Kanda (1897–1977). Wikipedia's Kyutaro Kanda entry records that he first specialized in both Tomoe Nage and Kata Guruma, then focused solely on the shoulder wheel because few judoka knew how to counter it; he refined it with Kano Jigoro and Kyuzo Mifune and became an expert after about three years. Wikipedia's Kata guruma entry adds that Mifune demonstrated three variations in The Essence of Judo, while Kanda invented some minor variations.
This biographical material comes from Wikipedia only, and the two entries echo each other, so they do not count as independent sources. This article therefore states only his years, specialty and teachers, and no competition results. For other throws from the same family, see the series entries on Tomoe Nage, Harai Goshi and Seoi Nage.
2. Mechanics: Control the Arm, Drop Level, Scoop In, Rotate
Different systems enter Kata Guruma differently. The Kodokan version (KokaKids) releases the lapel grip, bends the knees and grabs the opponent's leg, lifts him onto the back with leg drive, then pulls through with the sleeve and lowers him toward the mat. The wrestling version (Wikipedia's Takedown entry) pulls the opponent's elbow, puts the head under his arm, grabs the inside of his thigh with the other hand, then rises and drives to the side. For BJJ, Evolve's guide starts from arm control, and the table below follows it while noting where the systems differ.
| Stage | Key points |
|---|---|
| 1. Control the arm | Grip the wrist, sleeve or triceps so the opponent cannot pull away during the entry (Evolve) |
| 2. Drop level and step in | Bend the knees so your head and shoulders dip under the line of his arm, step inside with the lead leg and turn slightly so his weight is pulled forward (Evolve) |
| 3. Scoop the shoulder into the armpit | Slide the shoulder into his armpit while pulling his arm across your body to load his weight onto your back; the Kodokan and wrestling versions grab the leg or inner thigh here (Evolve, KokaKids, Wikipedia) |
| 4. Lift and rotate | Lift slightly with the legs and rotate to the side; the rotation is what sends the opponent over the shoulders (Evolve) |
| 5. Control the landing | Keep the grips and land in side control, north-south or a passing position (Evolve); the judo version pulls through with the sleeve and lowers toward the mat (KokaKids) |
Evolve lists five common mistakes: dropping straight down without stepping in, muscling the lift instead of using leg drive and rotation, not controlling the arm, poor timing that gives the opponent time to react, and letting go too early instead of keeping the grip to reach a stable position. KokaKids likewise stresses lifting with the legs.
Evolve also lists four entries: Arm Drag to Fireman's Carry, a collar-grip version in the gi, a hybrid with the single leg, and Snap Down to Fireman's Carry. In the gi, sleeve and collar grips make entries cleaner; in No-Gi, arm drags and wrist control create the opening, and the level change has to be faster because grips slip.
3. Entry Timing and Setups
The three entry points below are drawn from Evolve's fireman's carry article. They are technical descriptions, not statistical conclusions:
First, when the opponent grabs your arm or reaches for a collar grip. An outstretched hand is your chance to take his wrist or sleeve and begin controlling the arm.
Second, when he pushes forward aggressively or his weight is committed to one side. Evolve lists opponents who push forward aggressively or whose weight is committed to one side. By inference, once his weight has been drawn out like this, stepping in takes less effort (our inference, not stated by the source).
Third, as a counter from an upright tie-up or grip exchange. Evolve also presents it as a counter option from standing grip exchanges. Entries can pair with the series' Arm Drag, or with a snap down that pulls him low before the carry.
4. Strengths and Limitations
| Strengths | Limitations |
|---|---|
| The landing leads straight into side control, north-south or a passing position (Evolve) | Without arm control the opponent can escape or counter (Evolve) |
| Kanda reportedly chose it because few people knew how to counter it (Wikipedia's Kyutaro Kanda entry, single source) | Muscling the lift without leg drive and rotation can leave your own balance out of control (Evolve) |
| In judo, a throw that puts the opponent on his back with impetus and control scores ippon (Wikipedia, Judo) | Leg-grab versions are no longer legal in competitive judo (KokaKids, Wikipedia) |
| In IBJJF, establishing top position for 3 seconds scores 2 points (Exponential Jiu-Jitsu) | If the opponent initiates a guard pull first, a later takedown does not earn those 2 points (IBJJF Article 4.1.11) |
5. Common Counters
The sources used here do not cover "how to counter Kata Guruma" specifically. Below are general ideas from Evolve's No-Gi takedown defense guide that fit carry-style attacks. They are inferences from the source, not evidence about this throw.
First, the underhook. Evolve calls it the most used clinch hold for stopping an opponent's deeper entries: threading your arm under his arm to control his shoulders and upper body makes it hard for him to get his head under your arm. Pummeling drills help you win the underhook.
Second, the sprawl. Evolve stresses that sprawling is active: bring the lead leg back, use the hips to crush his shoulder or head, then counterattack from that position. A carry needs a low level to get under you, so driving your hips down denies him the rise.
Third, a front headlock after the sprawl. Evolve notes that after a successful sprawl you can grip the chin, drop your weight on the neck and attack with chokes such as the Guillotine, Anaconda, D'Arce or the necktie, with the guillotine the most used choke from the front headlock.
Follow-Ups When the Carry Is Stopped
When the arm gets pulled away, Evolve lists missing arm control as a failure cause, so go back to the grips: re-create the entry with an arm drag or snap down, then re-attempt the carry (a follow-up idea inferred from the source).
After a successful throw, Evolve advises not to let go early; keep the grips to reach a stable position, then advance to side control or north-south.

6. Competition Frequency and Rule Legality
On rules, Exponential Jiu-Jitsu's summary of the IBJJF rulebook states that establishing top position for 3 seconds earns 2 points for a takedown. Article 4.1.10 awards the 2 points to an athlete who initiates a takedown before the opponent initiates a guard pull; Article 4.1.11 says a takedown initiated after the opponent starts a guard-pull attempt does not earn them. That page was published in 2024/10, does not state the rulebook version, and also notes that slamming an opponent earns an immediate disqualification, so control the landing instead of dropping the person. For real competition, rely on the latest IBJJF rulebook.
In judo competition, KokaKids and Wikipedia both state that the common Kata Guruma versions involve gripping the trouser leg or legs and are illegal under current International Judo Federation (IJF) rules, with Wikipedia dating that statement to 2019. The throw nevertheless remains one of the 40 techniques of the Kodokan Gokyo.
As for frequency, IBJJF and ADCC publish only placings and brackets, not per-technique statistics, and we found no reliable third-party appearance rate for Kata Guruma, so this is qualitative only: in BJJ teaching it is usually presented as one takedown entry extending from arm drags, snap downs or standing grip exchanges, not as a standalone mainstream weapon.
7. Safety: Judo Injury Sites and Landing
We found no injury study specific to Kata Guruma, so only whole-sport judo data is cited. A 2018 systematic review by Bromley et al. in the British Journal of Sports Medicine, covering 9 prospective studies of Olympic combat sports followed for more than 12 weeks, found the most commonly injured sites in judo were the lower back (10.9%), shoulder (10.2%) and knee (9.7%). The authors also note inconsistent injury definitions and exposure calculations across studies, so injury severity cannot be compared directly between sports; these percentages are judo-wide figures and cannot be read as the risk of Kata Guruma itself.
・Lift with the legs rather than bending over and hauling with the lower back; KokaKids also asks for a leg lift
・Control the landing: pull through with the sleeve and lower him, do not slam him into the mat; an IBJJF slam earns disqualification (Exponential Jiu-Jitsu)
・The person being carried should practice breakfalls (ukemi): chin tucked, back rounded, slap the mat with the arm, never post a hand
・Beginners should train on soft mats with experienced partners; stop and seek medical evaluation for persistent lower back, shoulder or knee pain
FAQ
Is Kata Guruma the same as the fireman's carry?
The sources used here treat them as the same shoulder-carry throw: Kata Guruma is the Kodokan name, and fireman's carry is the usual English name in wrestling and BJJ. Details differ by system. The Kodokan version grabs the leg, while much BJJ teaching starts from arm control, so confirm specifics with your coach.
How many points does a Kata Guruma takedown score under IBJJF rules?
Establishing top position for 3 seconds scores 2 points. Under IBJJF Articles 4.1.10 and 4.1.11, a takedown started after the opponent has initiated a guard pull does not earn those 2 points. The rules summary cited here does not list legal techniques one by one, so check the latest rulebook.
Can you still use Kata Guruma in judo competition?
Not the leg-grab version. KokaKids and Wikipedia both say competitive judo bans gripping the trouser leg or legs, so the common variations are now illegal, though the throw remains one of the 40 techniques of the Kodokan Gokyo.
Can you do Kata Guruma in No-Gi?
Yes, with a different entry. Evolve notes that No-Gi relies on arm drags and wrist control to create openings, and the level change has to be faster because grips slip.
What if my opponent keeps pulling his arm away?
Control the arm before attacking. Evolve lists failing to control the arm as a common mistake because the opponent can escape or counter. Use an arm drag or snap down as the entry, then transition into the carry.
