I don't think the NCJA has a website anymore. It used to be hosted out of Idaho State University,and ws on the ISU Judo Club website.
We redid the ISU Judo website, and I am pretty sure we deleted the NCJA site. Not that it had much on it, or a list of all NCJA member clubs.
I suggest your e-mail Sami Tadehara, the current President of the NCJA. email@example.com.
Also, note that most college Judo clubs probably are NOT members of the NCJA. judoinfo.com would be a good place to start, as their state by state list may have some colleges/universities listed.
Collegiate Judo is in a sad state in the USA for sure.
Off the top of my head, here is a short list.
Slippery Rock State
San Jose State University
Idaho State University
University of Louisiana at Lafayette
Northern Arizona State University
Boise State University
University of Idaho (in Moscow-Meridith Bregman)
Miami-Dade Junior College
University of Texas at Austin
US Military Academy (Anapolis)
US Air Force Academy (Colorado Springs)
University of Colorado at Boulder
Auburn U. (I think..my old buddy Ruggero Galici)
David Matsumoto's club in the Bay Area
Hayward Nishioka's club (Cali)
I think Cal State Poly?
The East Coast Collegiate Judo Association has a web site, I think.
Maybe others can add to the list.
