The Kata-guruma (Shoulder wheel) consists of lifting your opponent onto your shoulders, spinning around, and throwing him to the opposite side.
This Waza can be performed by inserting your head into the armpit of either the Tsurite (Lifting hand) side or the Hiki-te (Pulling hand) side. After inserting the head into the armpit, Tori inserts one hand between Uke legs, and then lifts Uke onto his shoulders while pulling with the other hand. Tori then shifts his Center of gravity and throws Uke on the opposite side.
This Kata-guruma (Shoulder wheel) Waza is currently popular among Judo practitioners, and, because it can be performed with equal ease by both small and large combatants, it is frequently seen in competitions.
This Waza originated in the "Sambo" martial arts of the former Soviet Union, and smaller-statured but powerful Russian combatants are particularly skillful in its use.
This is also an easy Waza for relatively small women combatants to perform.
Although the Kata (Form) for this Waza is formally classified as a standing throw, in actual competition it requires Tori to burrow into Uke bosom.
