The version shown here is just one version; the reader should recognize that there will be variations among schools. Ji-in, Ji-on, and Jit-te form a group of kata used in Shotokan Karate and other karate styles, beginning with the same characteristic kamae of the left hand covering the right, which apparently has roots in ancient Chinese boxing. Their origin is thought to be from the Tomari-te school, however Hirokazu Kanazawa speculates that the Jion kata were devised in the Jionji 慈恩寺, the Jion temple, where martial arts were famously practiced. From there, Kanazawa believes the Jion kata were spread into the Tomari region.
