Definition
Yoko guruma (Japanese: 横車, literally “side wheel”) is a judo throwing technique classified as a sacrifice (sutemi-waza) technique. It involves the tori (the executor of the technique) falling to the side while using a wheel‑like motion to throw the uke (the receiver) over the tori’s body.
Overview
Yoko guruma is one of the many techniques taught in modern judo, though it is not part of the original 40 throws of the Kodokan Gokyo‑no‑waza. It is typically learned at advanced levels and is employed in both competitive and kata contexts. The technique is considered a side sacrifice throw, wherein the tori intentionally drops to the side to create leverage, allowing the uke’s center of gravity to be shifted forward and over the tori’s body, resulting in a controlled throw onto the mat.
Etymology/Origin
The term combines the kanji 横 (yoko), meaning “horizontal” or “side,” and 車 (guruma), meaning “wheel” or “cart.” The name reflects the lateral, wheel‑like motion executed during the throw. The technique originated in the early 20th century as part of the evolution of judo’s repertoire, drawing on principles of balance and kuzushi (off‑balancing) articulated by Jigoro Kano, the founder of judo.
Characteristics
- Classification: Nage‑waza → Sutemi‑waza → Yoko‑sutemi (side sacrifice)
- Mechanics: The tori steps to the side of the uke, establishes a grip (often sleeve‑lapel or lapel‑collar), and drops onto the side while rotating the hips and torso, creating a wheel‑like pivot. The uke is pulled forward and over the tori’s body, landing on their back or side.
- Grips: Commonly executed from a standard right‑hand lapel, left‑hand sleeve grip, though variations exist with double‑lapel or belt grips.
- Safety considerations: Because the tori falls to the mat, practitioners must ensure both parties breakfall correctly to avoid injury.
- Competitive use: Yoko guruma is legal in judo competition but is less frequently seen than more common throws (e.g., seoi‑nage, ippon‑seoi‑nage) due to its high risk and the need for precise timing.
