O soto guruma video
Info about "O soto guruma video"
O soto guruma (big outer wheel), is one of the original 40 throws of Judo as developed by Jigoro Kano. It belongs to the fifth group, Gokyo, of the traditional throwing list, Gokyo (no waza), of Kodokan Judo. It is also part of the current 67 Throws of Kodokan Judo. It is classified as a foot technique, ashi waza. 
Using the hands as O soto gari, tori enters in the same way, but attacks both legs by creating a bar behind ukes legs. Because both legs are hit, there is much less sweep and this technique becomes somewhat of a reverse O guruma or Ashi guruma.
