The United States Jujitsu Association is dedicated to the basic tenants of Bushido. Its goals are to provide practical jujitsu applications for self-defense to both the jujitsu enthusiast and the average person desiring fundamentals of self-defense. Jujitsu has a deeply rooted traditional history. The United States Jujitsu Association respects these traditions. Jujitsu is also the parent art of judo. The USJJA was founded by Thomas Crone Shihan, judo Shichidan (as well as a jujitsu practitioner under many disciplines since 1955). Much of the value added to jujitsu by judo is appreciated and incorporated. Crone Senseiís credentials can be found under the "Founder" heading.
Jujitsu has always had many ryus, or schools of thought and method. In itself, the USJJA has no particular ryu designation. No particular underlying philosophical principle or physical application dominates. It does have philosophical, spiritual, and technical particulars that set it aside from other jujitsu disciplines, but they cannot be summarized for the sake of nomenclature or categorization. At the same time that it is distinct, it is encompassing and accepting of many styles. The idea sometimes expressed by some ryus, "This is our style, and it is superior," is not endorsed by the USJJA. More acceptable perspectives are: "This might work better done this way," and "This works well this way," are functional approaches rather than positional statements. Functional approaches and perspectives are consistent with the USJJA philosophy.
