Seoi nage (背負投) is a shoulder throw, one of the traditional forty throws of Judo as developed by Jigoro Kano. It belongs to the first group, Dai Ikkyo, of the traditional throwing list, Gokyo (no waza), of Kodokan Judo. It is also part of the current 67 Throws of Kodokan Judo. It is classified as a hand technique, te-waza, and is the second throw performed in the Nage-no-kata.
The specific techniques of morote-seoi-nage (two hands seoi-nage), or eri-seoi, are usually generalised as simply seoi-nage. The distinctive technical aspect of this classification is that tori (the one executing the technique) grips with their two hands, as opposed to Ippon Seoi Nage, in which only one hand remains gripping while the other slides under uke's (the one receiving the technique) armpit. Additionally, reverse seoi-nage involves spinning up to 360 degrees so that uke ends up being thrown backwards rather than forward, as in other variations. Renowned seoi-nage martial artists are Isao Okano and Toshihiko Koga, and renowned reverse seoi-nage judoka is Choi Min-ho, who popularised the variation.
