Tachi-waza (Standing techniques)
"Tachi-waza" (Standing techniques) are performed from a standing posture, and they refer to Nage waza (Throwing techniques) which include Te waza (Hand techniques), Ashi waza (Foot / Leg techniques), and Koshi waza (Hip techniques).
Kodokan Judo lists 15 Te waza (Hand techniques), including the Seoi-nage (Shoulder throw), Tai-otoshi (Body drop), Kata-guruma (Shoulder wheel), Sukui-nage (Scooping throw ), Morote-gari (Two-hands reap), and Ippon-seoi-nage (One-armed shoulder throw), etc., 11 Koshi waza (Hip techniques), including the Uki-goshi (Floating hip throw), O-goshi (Large hip throw), Harai-goshi (Hip sweep), Sode-tsurikomi-goshi (Sleeve lift-pull hip throw), etc., and 21 Ashi waza (Foot / Leg techniques), including the De-ashi-barai (-harai) (Forward foot sweep) , Osoto-gari (Large outer reap), Ouchi-gari (Large inner reap), Harai-tsurikomi-ashi (Lift-pull foot sweep).
Nearly all Tachi-waza (Standing techniques) utilize Tai-sabaki (Body shifting / Body control) maneuvers to destabilize and throw an opponent without falling oneself. There are Kaeshi-waza (Counter techniques) to Tachi-waza (Standing techniques), and their successful execution requires speed and intuition, making them one of the more interesting aspects of a contest.
