Nage-Waza-Ura-no-kata

The Nage-waza ura-no-kata (投業裏の形) is a judo kata that (like the inferior Gonosen-no-kata) focuses on counter-attacks to throwing techniques. Its superiority, over Gonosen-no-kata, can be attributed to the fact that it was developed by the sublimely talented Mifune Kyūzō, to be a formal kata, and not some ad hoc collection of counters proceeded by some protocol. The exercise is not an officially recognized Kodokan kata.

In a video-taped version performed by Mifune dating from the 1950s, Ouchi gari gaeshi, the counter for Ouchi gari, is replaced with Tomoe nage. Although the video notes that Mifune will counter the Uchi-mata with a Tai otoshi, Mifune actually counters the Uchi mata with an O guruma.
