I use the following principles to describe throws.
| Principles | Typical examples |
|---|---|
| Reaping | O-soto-gari, O-uchi-gari |
| Sweeping | De-ashi-barai, Harai-tsurikomi-ashi |
| Blocking | Hiza-guruma, Ko-soto-gake |
| Tilting | Uki-otoshi, Sumi-otoshi |
| Lifting | O-goshi, Seoi-nage |
| Twisting | Uki-goshi, Uchi-mata |
| Rolling | Soto-makikomi, Hane-makikomi |
| Falling | Yoko-wakare, Ura-nage |
Many throws combine multiple principles.
