Kokyu-nage, 13th form

Your partner grasps your wrists from behind. Move your body backwards and push your hands forward. Simultaneously, twist your wrists slowly and lower your body by bending at the knees. Escape to your partner's side. Still pushing your power through your fingers, lower your hands to the mat, thereby throwing your partner. This technique calls for complete harmony and understanding between partners. If you use strength, you will make your partner resist or break his grip.
