Kobudo arts are thought by some to be the forerunner of Karate, and several styles of that art include some degree of Kobudo training as part of their curriculum. Similarly it is not uncommon to see an occasional kick or other empty-hand technique in a kobudo kata. The techniques of the two arts are closely related in some styles, evidenced by the empty-hand and weapon variants of certain Kata. For example, Kanku-dai and Kanku-sai, and Gojushiho and Gojushiho-no-sai, although these are examples of Kobudo Kata which have been developed from Karate Kata and are not traditional Kobudo forms. Other more authentic Kobudo Kata demonstrate elements of empty hand techniques as is shown in older forms such as Soeishi No Dai, aBo form which is one of the few authentic Kobudo Kata to make use of a kick as the penultimate technique.
