Maki-komi or ‘Winding throws’. These involve taking a normal throw and then adding an extra movement or action: landing on top of the attacker after the throw so as to cause extra damage.
They can be quite dangerous and also leave you vulnerable to attacks from other people so are not used too often.
Soto-maki-komi (outer winding throw)
Ko-uchi-maki-komi (minor inner winding throw)
Harai-maki-komi (sweeping, winding throw)
