Father of a Large Family

Because jujutsu is both so encompassing and has its origin hundreds of years ago, it has become the foundation for a variety of styles and derivations today. As each instructor incorporated new techniques and tactics to what was taught to them originally, they could codify and create their own ryu or school. Some of these schools modified the source material so much that they no longer considered themselves a breed of jujutsu. Modern judo is the classic example of an 'art' which was derived from jujutsu but is today distinct. Another layer removed, some popular arts had instructors who studied one of these jujutsu-derivatives and made their own derivative on top. This creates an extensive family of martial arts and sports which can trace their lineage to jujutsu in some part.

The following are a few different schools of jujitsu:

Araki Ryu Kogusoku
Danzan Ryu
Daito Ryu Aiki Jujutsu
Hontai Yoshin Ryu
Fudoshin Ryu
Hakko Ryu
Koppo Ryu
Takenouchi Ryu
Saigo Ryu Aiki Jujutsu
Sekiguchi Shinshin Ryu
Shin No Shindo Ryu
Sosuishitsu Ryu
Takeuchi Ryu
Tasumi Ryu Heiho
Tenji Shinyo Ryu
Yagyu Shingan Ryu
Yoshin Ryu

After the transplantation of traditional Japanese jujitsu to the US, many of these more traditional styles underwent a process of adaptation at the hands of their American practitioners, moulding the arts of jujitsu to better mesh with American culture in its myriad varieties. There are today many distinctly American styles of jujitsu, a defining characteristic of which is their constant, continued refinement and adaptation at the hands of their advanced practitioners. The following are a few examples.

Scottish Ju Jitsu Association
American Jui Jitsu Federation
Dano Shen Ryu
New York Jiu Jitsu
Sanuces Ryu
Small Circle Jujitsu
Vee-Arnis-Jitsu
Yoshitsune Jujitsu

The following martial arts and sports either do not always classify themselves as jujutsu or have founding instructors that studied a derivative of jujutsu.
