Kosoto Gake (小外掛), sometimes known as "minor outer hook", the English translation,[citation needed] is one of the original 40 throws of Judo as developed by Jigoro Kano.

It belongs to the third group, Sankyo, of the traditional throwing list, Gokyo (no waza), of Kodokan Judo.

He then steps forwards diagonally to place all of uke's weight on the foot tori wishes to reap.

This should all be done in a fluid motion so that uke's weight is moving backwards whilst the leg is being reaped, otherwise it will be too heavy to lift although the throw can still work sometimes from this position.

The opposite of this is Gyaku-kosoto Gake (Reverse Minor Outside Hook), which resembled the "step-over takedown" and is the first "throw" taught in Yanagi-Ryu.
