Kodokan–Totsuka rivalry

The rivalry between the Kodokan school of judo and the Totsuka school of Yoshin-ryu jujutsu happened in the 1880s during the Meiji Era in Japan. Consisting of several challenges and tournaments, its result saw the decline of the traditional jujutsu schools and the rise of judo as an institutionalized martial art. Although surrounded in controversy and legend because of inconsistent sources, it has been considered a vital part of the history of judo.
