Look for both legs scissoring around the opponent’s lower body during a sideways sacrifice action; this technique is prohibited in IJF competition.
Starting position
A standing exchange. Use the reference image and video to identify relative stance, movement direction, and distance; learn the physical setup from an instructor.
Typical grip
Grip and handedness vary by entry. Identify the visible sleeve, lapel, belt, torso, or leg controls in the reference, then confirm the club’s preferred grip with an instructor.
Kuzushi · balance breaking
For recognition, observe the direction in which the opponent’s balance is moved before the defining crab scissors action appears.
Tsukuri · entry and position
Locate the attacker’s sideways sacrifice direction and the wheel, hook, or separation it creates. Compare that defining shape with nearby techniques in Yoko-sutemi-waza · side sacrifice throws.
Kake · completion
In the reference or video, follow the coordinated upper- and lower-body action through the point where the opponent’s support is removed. Physical completion must be learned on mats.
Expected result
The reference outcome is a controlled projection to the mat with the attacker retaining balance or appropriate sacrifice control.

Common beginner mistakes
•
Identifying the technique only from the final pose instead of its defining body relationship.
•
Confusing it with another technique in Yoko-sutemi-waza · side sacrifice throws.
•
Trying to reproduce physical mechanics from a single illustration instead of learning them from an instructor.
Coaching tips to discuss in class
•
Connect the Japanese name with the English meaning: “Crab scissors.”
•
Focus on the attacker’s sideways sacrifice direction and the wheel, hook, or separation it creates.
•
Compare the reference image with the embedded video, then ask an instructor to confirm what distinguishes the technique.
