O Guruma video
Info about "O Guruma video"
O guruma (big wheel) is one of the original 40 throws of Judo as developed by Jigoro Kan. It belongs to the fourth group of the traditional throwing list in the Gokyo no waza of the Kodokan Judo.
It is also part of the current 67 Throws of Kodokan Judo. It is classified as a foot technique (ashiwaza). In Danzan Ryu jujutsu, it is known as Soto Momo Harai (Outer Thigh Sweep). 
Tori creates a bar in front of ukes legs and the hands throw uke over this leg. It is often said that an O guruma and Ashi guruma are the same, just with the leg in O guruma above the knee, in the latter below. However, the circle in O-guruma is more vertical, in Ashi-guruma horizontal.
