Archive:Deashi harai
Deashi Harai is one of the original 40 throws of Judo as developed by Jigoro Kano. It belongs to the first group, Dai-ikkyo, 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.
Technique Description
Judo: Uke steps forward. Tori sweeps uke's forward steping foot. Uke takes a hard fall. The technique is so simple and efective, it requires no hazuzhi (off ballancing of uke) and can be done even without a hold on uke by tori. Extremely effective against "dancing boxers".
DZR: Tori pushes uke back. As uke steps back and shifts his weight back, tori sweeps uke's forward foot, pulls him in (hazushi), and guides him down a side.

Demonstrated from http://www.judoinfo.com/gokyo1.htm, although if the distinction is made, looks a lot like DZR's Soto Gama.
Tournament from http://www.judoinfo.com/video8.htm, although if the distinction is made, this is really a good example of Okuriashi Harai, aka DZR's Okuri Harrai. It's often the case the techniques done in tournaments are fuzzy and hard to categorize.
