Overview

Katatedori Koshi-nage is the fundamental hip throw in aikido. When grabbed at the wrist, you enter deeply, turn your hip under the opponent's center, and throw them over your hip. Unlike judo's hip throws which rely primarily on lifting, aikido's koshi-nage emphasizes entering to the opponent's center and using circular motion. This is one of the most powerful throws when executed correctly.

This technique demonstrates using your center (hip) to control and throw the opponent's entire body.
