names to the original Jikyō-ryū curriculum: Notes on differences Although they may share the same name, the actual technique from Jikyō-ryū may differ in its entirety from the Mugai-ryu homonymous. There is no set called Go-ō 五応 in Jikyō-ryū. The Mugai-ryū's Hashiri-gakari (走り掛り), Iai no kata (kumitachi)(居合之形) and the Wakizashi no kata (脇差之形) sets do not exist in Jikyō-ryū and neither do they have any homonymous technique in the Jikyō-ryū curriculum. There are other sets in Jikyō-ryū that are not present in Mugai-ryū Iai Hyōdō. Also, although Nakagawa had access to several Jikyō-ryū's densho (scrolls and manuscripts), he was not fully instructed in them. This is apparent in his explanation of the densho called Yōhō(Mochiikata) Nijūgoka-ji(Nijūgoka no koto) (用方二十五箇事), where he admits his ignorance about the concept of "misumi" (三角), for instance. Other evidences of his incomplete instruction can be seen in his explanation on the length of the sword and on the sageo(下緒), both lacking crucial information for a true Jikyō-ryū practitioner, among other teachings and oral instructions that are not seen in Mugai-ryū Iai Hyōdō. The grading system used in Mugai-ryū Iai Hyōdō is based on the modern dan/kyū systems of modern martial arts like judo and kendo. Jikyō-ryū and Mugai Shinden Kenpō employ an older grading system, used during the Tokugawa Shogunate.
