In Jiu-Jitsu there are five main sectors ("arts") of training. The first, the Art of Blocking, is used to defend against attacks. The second, the art of the Fulcrum Throw, is employed in modern judo. The third, the Art of the Non-fulcrum Throw is employed through throws involve little or no contact with the opponent. The fourth, the Art of Escaping (Hakko-Dori), is very crucial in many styles of Jiu-Jitsu. The fifth is the Art of Striking (Atemi-Waza).
Some examples of martial arts that have been developed from or have been influenced by jujitsu are: Aikido, Hapkido, Judo (and thence Brazilian Jiu-Jitsu, and Sambo), and Kempo- as well as some styles of Japanese Karate. The Wado-ryu school of Karate, for example, is considered as a branch of Shindo Yoshin-ryu Jujutsu which has received strong influences from Okinawan Karate.
The Japanese systems of hakuda, kempo, and shubaku display some degree of Chinese influence in their emphasis on atemi-waza. In comparison, systems that derive more directly from Japanese sources show less preference for such techniques. However, a few Jiu-Jitsu schools likely have some Chinese influence in their development. Jiu-jitsu ryu vary widely in their techniques, and many do include significant emphasis on striking techniques, though in some styles only as set-ups for their grappling techniques.
