Judo Level 7: Osoto Guruma — A rear axis across both legs

大外車, o-soto-guruma, combines major outer and wheel and belongs to foot techniques.

Backward imbalance and the leg axis work together. Blocking legs alone does not explain the throw if the upper body remains over its base.

O-soto-guruma uses tori's leg as an axis behind both of uke's legs with backward imbalance in Kodokan's definition. Read both supporting legs relative to that axis rather than interpreting the name as a very large outside reap.

O Guruma rotates the partner forward over a higher axis; Osoto Guruma uses a rear axis. Guruma does not imply one direction.

The name resembles o-soto-gari but the leg's role differs. O-soto-guruma rotates uke across an axis associated with both legs. A backward fall alone cannot identify it.

Do not strike behind the knees or twist them. Let an instructor check position and distance; do not add sweeping force to compensate for a wrong direction.

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.

Rewind before leg contact and ask about upper-body direction. Blocking both legs while uke remains balanced copies a pose without its conditions. Have the instructor arrange the practice and receiving path.
