 Go-no-sen-no-kata

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.
