Gonosen-no-kata (後の先の形, Forms of counter attack) is a judo kata that focuses on counter-attacks to throwing techniques. It is not an officially recognized kata of judo, but its importance is attested to by its inclusion in Kawaishi's The complete seven katas of judo. Writing in the early post-war period, Kawaishi described the kata as being practiced less in Japan than in Europe.^[1]

However, according to recent scholarly research, gonosen-no-kata likely never even existed in Japan. After Japanese judoka from Waseda University in Tokyo visited England in the 1920s and publicly demonstrated several counter-techniques developed at their home University, the exercises were henceforth in Britain (and later in France and other parts of Europe) represented as a formalized kata and practiced and taught that way by Kawaishi Mikinosuke, Koizumi Gunji, Ōtani Masutarō, and Tani Yukio.^[2]
