Short Answer

Ko Soto Gake combines backward imbalance with an outside leg hook. Its name resembles Ko Soto Gari, but leg function differs; watch beyond one contact frame.

Key Takeaways

  • Identify outside hooking contact.
  • Follow continued leg contact after entry.
  • Compare upper-body direction with the thrower’s base.

Follow the foot after contact to see how the hook continues working. This helps distinguish gake from gari.

What the name tells us

小外掛, ko-soto-gake, is a foot technique. Soto means outside and gake suggests hooking.

How the technique works

Kodokan describes backward imbalance, an outside hook and lifting the body into the throw. Read the hook alongside hands and torso rather than as a static obstruction.

Ko-soto-gake emphasizes hooking from outside and lifting uke's body in Kodokan's description. The entry can resemble ko-soto-gari, but the hook maintains a leg-to-body relationship rather than simply reaping through the base.

What to watch in the clips

  • Identify outside hooking contact.
  • Follow continued leg contact after entry.
  • Compare upper-body direction with the thrower’s base.

A distinction worth noticing

Ko Soto Gari emphasizes reaping, Ko Soto Gake hooking. The difference is more than a spelling change, and twisting a knee is not a way to demonstrate it.

Overlapping legs during the fall can obscure gake versus gari. Rewind before the fall and inspect upper-body movement. A single final image has limited value for naming the technique.

Taking the lesson back to practice

Have an instructor check distance and both partners’ knee alignment before movement. Stop if twisting is felt; do not reach into a hook that destroys your own base.

The Level here refers to the IMAC Dojo curriculum. Use the article and clips to prepare questions and review them with your instructor. Practical training needs a suitable partner, space and controlled conditions.

Ask how the hooking leg relates to tori's standing base and whether uke has already been unbalanced backwards. Catching a leg while losing your own support is a separate problem, not evidence of readiness for speed.
