Ippon-seoi-nage (One-armed shoulder throw)

Ippon-seoi-nage (One-armed shoulder throw)


This is a variation of the Seoi-nage (Shoulder throw), and is one of the most fundamental Te waza (Hand techniques) in Judo.

Features of this Waza

The Ippon-seoi-nage (One-armed shoulder throw) consists of grasping one of the opponent's arms, spinning around to place your back against him, and then throwing him to the floor over your shoulder.
This Waza begins by grasping the sleeve of Uke (Player receiving opponent's attack) Hiki-te (Pulling hand). While grasping his sleeve, Tori (Player executing technique) spins around to put his back against Uke (Player receiving opponent's attack). Tori (Player executing technique) then uses his free Tsurite (Lifting hand) to clamp Uke (Player receiving opponent's attack) upper arm in the crook of his elbow, pulls him forward, and throws him over his shoulder. When performing this throw, Tori (Player executing technique) feet are spaced at shoulder width, and his knees extend as the throw unfolds.
Just as with the Seoi-nage (Shoulder throw), variations of the Ippon-seoi-nage (One-armed shoulder throw) are a common sight in Judo competitions.
In cases where Uke (Player receiving opponent's attack) evades all attempts by Tori (Player executing technique) to grasp his Hiki-te (Pulling hand) sleeve, the Waza can be entered by grasping Uke (Player receiving opponent's attack) Hiki-te (Pulling hand) collar instead of the sleeve.

Waza details

Although this Waza entails destabilizing Uke (Player receiving opponent's attack) balance in the forward direction, there are cases in actual competition when it's preferable to forcefully execute the pull and throw by using one's back muscle strength, and this requires strengthening the back muscles.

Waza usage tip

  • After spinning around to place your back against the opponent, you must clamp his upper arm firmly in the crook of your elbow.
