There are three different organizations that govern Judo in the United States of America. There is the United States Judo Association (USJA) that was founded in 1968 by a group of men. The USJA is mostly concentrated in California and Florida but also popular in the Midwest and southeast. The second organization is the United States Judo Federation (USJF) and started in 1952. The concentration of the USJF is on the east and west coast but also in Chicago and Hawaii. USA Judo, or United States Judo, Inc. (USJI), is the third organization with its headquarters in Colorado Springs, Colorado. The USJI is the largest organization.

The sport was first introduced to the states in about 1902 when a former US President, Theodore Roosevelt, practiced in the White House. Judo really began to develop in the 1950s when it became required for the US Air Force to learn. After these advances it was officially recognized as an AAU sport and there have been national competitions and tournaments ever since. The United States formed an Olympic team and competed in the 1964 summer Olympics and still continue to do so to this day. Now, Judo is practiced by more than 400,000 Americans, including men, women, and children.
