What are the USJA, USJF, and USJI?
The three largest judo organizations in the United States are the USJA, USJF, and USJI. There are no differences in the training methods or type of judo taught because that is up to the instructor. Most generalizations would be wrong when applied to a particular club or member, and most judo instructors belong to 2 or 3 of the organizations. Each organization is stronger in some areas of the country. The USJF and USJA are working well together via their Grassroots Judo programs. The biggest differences are historical.
All of these organizations have the authority to issue rank, which is recognized by the other two national organizations and the International Judo Federation. They also offer insurance. The most important thing to consider when choosing a Judo club is the teacher and the atmosphere of the club, regardless of its affiliation. All three organizations recognize each other and (usually) allow members of the other two organizations to participate in their events.
The USJF, USJA, and USJI provide liability insurance which protects the person hosting events, practices or whatever in case someone decides to sue. There is no real difference in liability coverage given the miniscule odds of a lawsuit. Many event organizers and club coaches require this insurance for their own protection. You can buy both business insurance and event insurance, and some people do, but most judo clubs are run on a shoestring budget and do not. The USJF and USJA offer secondary memberships, so a member of one of these organizations can become a member of the other organizations with a minimal extra fee, however, no additional insurance is provided.
