Kata Ha Jime

Kata-ha-jime - Single Wing Strangle

Kata-ha-jime - the single wing strangle, is shown in the Katame-no-kata as a follow on from a failed okuri-eri-jime attempt.

From behind, tori places one hand around uke's neck and holds uke's furthest collar. To defend from a possible okuri-eri-jime, uke lifts their arm to throw tori over their shoulder.

Here is a video of the application of the technique:
