Are omoplatas legal in judo? Though they cause pain to the shoulder joint, they "lock" the elbow joint (in a bent position) to achieve this (as in ude-garami and te-gatame).

1 Answer 1


Yes, omoplatas are considered a variant of ashi-gatame or hiza-gatame.1 3 The IJF Referee Commission has confirmed their legality on multiple occasions,1 2 both as a submission, and as a turnover:

Lascau: Osaekomi.

Demonstrator: *uke taps, tori points at armlock*

Lascau: Ippon. Ippon.

Demonstrator: [With this movement,] making the kansetsu-waza? [It's ok?]

Lascau: Ippon. No problem. Ashi-gatame. Ashi-gatame, combination with rolling, and then osaekomi or ashi-/hiza-gatame, depending how is the hand.

They are occasionally seen in competition, and are the signature techniques of some high level judoka (e.g. Huizinga, Munkhbat):
