The Soto-makikomi (Outer wraparound throw) Waza consists of the attacker wrapping his opponent around his own body between the waist and back, and then throwing him down.
Tori (Player executing technique) grasps the outer side of Uke (Player receiving opponent’s attack) sleeve near the upper arm with his Hiki-te (Pulling hand), and grasps the back of Uke collar with his Tsurite (Lifting hand).
Tori then steps forward with his Tsurite (Lifting hand) side leg, placing it between Uke (Player receiving opponent's attack) feet, and turns on the sole of his foot, placing his Hiki-te (Pulling hand) side foot against Uke heel.
Tori then shifts his Center of gravity to his Hiki-te (Pulling hand) side leg, making that his support leg, and extends the Tsurite (Lifting hand) side leg around and against (snugly) the outer side of Uke body. After grasping Uke upper body, Tori twists to wrap an arm around Uke from his waist to back, and then throws Uke while sacrificing his own posture.
To grasp Uke upper body, Tori pulls Uke toward him with his Hiki-te (Pulling hand), then releases his Tsurite (Lifting hand) and wraps it around Uke (from over his head) thus pinning his arms to his sides.
