The Hane-makikomi (Springing wraparound throw) consists of a wraparound Waza in which the combatant sacrifices his own posture.
The Hane-makikomi (Springing wraparound throw) Waza is used by an attacker when his initial Hane-goshi (Hip spring) Waza failed to adequately turn the defender's body.
The Hane-makikomi (Springing wraparound throw) Waza is the same as the Hane-goshi (Hip spring) Waza in that Tori (Player executing technique) destabilizes Uke (Player receiving opponent's attack) toward Tori Hiki-te (Pulling hand) side, with Tori then bending his knee to a 45-degree angle and throwing his opponent as if riding on him. In cases where Uke body rotation is insufficient, Tori sacrifices his own posture and wraps himself around Uke in order to throw him.
To perform a Hane-goshi (Hip spring) throw, Tori releases his Tsurite (Lifting hand) grasp and wraps his arm around the back of Uke neck so that Tori body is snugly against Uke upper body, thereby enabling the throwing force to be applied efficiently. As Tori Tsurite (Lifting hand) destabilizes Uke in the forward and down direction, Tori bends his throwing leg knee to a 45-degree angle and effectively uses the spring of his support knee to flip Uke upward and throw him.
In order to keep Uke body snugly against him until the throw is completed, Tori does not allow his own body to bend excessively.
Because Uke is behind Tori after the throw, there's a risk that the Waza was not effective, so Tori must maintain his guard. This throw is often followed by a Waza such as the Kesa-gatame (Scarf hold), etc.
