Seoi nage  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. Seoi nage is likely to have developed from the jujutsu throw "empi nage" in which an arm bar is used as leverage to throw uke over tori’s shoulder.
