[1] The attacker places the sole of the foot against the opponent's knee, then uses a circular pulling motion with the hands to rotate the opponent over the pivot point. [1] It is classified in the first group of the Gokyo no Waza. [1]

History & Origin

Classified in the Kodokan Judo syllabus. [1]

Effectiveness

A fundamental throwing technique that relies on timing and technique rather than strength. [1] Effective against advancing opponents and as a counter-technique. The wheel mechanics make it efficient — minimal energy for maximum effect when timed correctly. [1]

Lineage

Kodokan judo lineage: Jigoro Kano (1860–1938) systematized this technique as part of the Kodokan judo curriculum. Transmitted through the Kodokan instructor system to judo federations worldwide. Adopted into BJJ through Mitsuyo Maeda → Carlos Gracie → the Gracie family lineage. [1]

Competition Record

Recognized Kodokan judo technique but rarely seen in modern IJF competition due to rule changes favoring forward-throwing techniques. Occasionally appears in kata demonstrations and regional tournaments. [1]

Training Notes

The sole of the foot must contact FLAT against the knee — not the toes
The pulling motion must be CIRCULAR, not straight — think of spinning a wheel
Timing is everything — block the knee at the moment the opponent commits weight to that leg
Practice with uchikomi to develop the timing

Common Mistakes

!Pushing the knee instead of blocking it — this warns the opponent
!Pulling straight instead of circularly — the wheel effect is lost
!Blocking too high (thigh) or too low (shin) — the knee is the pivot point
!Not committing to the pull — half-hearted attempts fail
