Kosoto Gake (Minor Outer Hook) is another excellent weapon to deploy in a Judo or submission grappling match, in the gi or no-gi. The setups described in the demonstration above work the same way regardless of whether you’re wearing a gi, rashguard, or other apparel.
The key to a good Kosoto Gake is establishing the outer hook around the leg. In the setup I provide in the video, the throw is completed off of a body lock, but this is just one of many ways to land a Kosoto Gake.
The first, most basic way of completing the throw is to chop back with the outer hook while leaning forward. The element of surprise is crucial here – the chopping of the leg must occur in conjunction with the establishment of the outer hook. Once completed, there is a good chance you will wind up in an opponent’s half-guard, which is why, for submission grappling, I like the second version better.
The second version, sometimes known in wrestling as a “Polish throw”, involves balancing on the balls of my hooking foot while pivoting with my right foot, then sweeping him back with the outer hooking leg as I turn my hips. Now I am able to complete the throw for high impact and land in side control.
I sometimes refer to this setup as an “intelligent ragdoll”. At first glance, when done quickly, the setup and throw looks like a ragdoll, but when broken down you will notice subtle scheme of footwork at play, enabling the throw to happen.
