This technique is performed in exactly the same way as Katate-Dori Irimi-Nage. There are three ways of detaching your hands.
Detachment at the upper position
Detachment at the medium position
Detachment at the lower position.
Detachment at the upper position:
Swing your hands upward while turning your body obliquely, insert your right hand from beneath to effect the detachment and begin the Irimi process.
Detachment at the middle position :
Turn your body in a manner similar to Shiho-Nage Ura-Waza, then grasp your partner's wrist and unleash Irimi.
Detachment at the lower position :
Turn your body in a manner similar to Shiho-Nage Ura-Wasa, then grasp your partner's wrist and unleash Irimi.
