Also known as Koshi Guruma — the canonical term used on this site.
English rendering of koshi guruma
Head and arm hip throw is the English rendering of koshi guruma — “koshi” meaning hip and “guruma” meaning wheel, with the head-and-arm wrap describing the grip.
Etymology. The name translates the judo term and adds the controlling grip: the attacker wraps the head and an arm, then wheels the opponent over the hip. “Head and arm hip throw” makes both the grip and the hip-wheel explicit.
Mechanics. The throw’s power is leverage, not size: the hip wedges under the opponent’s centre as a fulcrum, and the force angle of the head-and-arm wrap rotates them over it, so a smaller attacker can throw a larger one by setting the angle correctly.
