Okuriashi harai or Okuri ashi barai (送足払) is one of the original 40 throws of Judo as developed by Kano Jigoro.
It belongs to the second group of the traditional throwing list in the Gokyo no waza of the Kodokan Judo.
Okuriashi harai is a double foot sweep from standing position.
The sweep is most effective against a retreating opponent and does not work if just one of his feet leaves the ground.
