Although these arts are most commonly referred to under the general rubric of "jujutsu," there were many different names for these types of techniques and tactics, varying from ryu to ryu. Hade, hakuda, jujutsu, kempo (Sekiguchi-ryu, Araki-ryu, Seigo-ryu), koppo, kogusoku, and koshi no mawari (Takenouchi-ryu and Yagyu Shingan-ryu), kowami, kumiuchi, shubaku, tode, torite, yawara[jutsu] (Tenshin Shoden Katori Shinto-ryu, Tatsumi-ryu and Shosho-ryu), and yoroi kumiuchi (Yagyu Shingan-ryu) are a few of the words that were used over the years. In some traditions, such as the Takenouchi-ryu and Yagyu Shingan-ryu, more than one term was used to refer to separate parts of their curricula. Each of these words denotes systems with different contents or slightly varied technical characteristics.
