Judo Level 4: Okuri Eri Jime — Separate the two collar-hand roles

送襟絞, okuri-eri-jime, is a strangle technique. Eri means collar, distinguishing it from non-cloth Hadaka Jime.

Kodokan describes different collar positions and hand directions from behind. This article identifies structure; the instructor checks actual placement and pressure.

Okuri-eri-jime uses the collar as the medium of control. Kodokan describes one hand passing in front of the neck and another beneath the armpit to the other collar. Read both hands together; one collar grip near the neck does not reveal the whole structure.

Kata Ha Jime uses one arm to control the partner’s arm differently. A shared rear approach does not make the names interchangeable. Watching only one collar can conceal this distinction.

Cloth use distinguishes it from hadaka-jime, while kata-ha-jime adds a specific relationship to arm control. From behind they can appear similar, so seek a view that reveals the grips.

Review names and grips with an instructor without strangle pressure. Agree on stop signals and release immediately; do not pull cloth harder to test whether the grip is correct.

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.

Use the clip to identify arm routes and grips before asking your instructor, not to test progressively stronger collar pulls. Practice must allow signalling and immediate release, not endurance of a strangle.
