Ju Jitsu is one of the few genuinely effective and practical martial arts. It emphasizes skill over strength and does not rely on any single aspect of combat eg, kicking, like many modern styles, rather the whole spectrum of combat skills are taught, from locks and throws, to striking and ground fighting. While this may sound like a lot to learn Ju Jitsu is easily accessible and just a few months training will provide you with many invaluable self-defence skills.
Ju Jitsu is one of the oldest martial arts, dating back to the great Samurai of feudal Japan and senior grades are taught to use traditional Japanese weapons, eg. the katana
Many modern combat styles originate from Ju Jitsu: in the early 20th century Christian Japanese developed Aiki Jutsu from Ju Jitsu which later evolved into Aikido. In 1882 Jigaro Kano developed the sport version of Ju Jitsu, namely Judo.
Yukio Tani, one of the first people to introduce Ju Jitsu to this country, toured Britain taking on all comers to demonstrate the prowess of Ju Jitsu as a fighting art. One of his opponents was a circus strongman named "Vilrow", who was Sensei Jenkinsons great Grandfather!
