What is judo?

Judo (joo-doh) means “the way of gentleness” or “the gentle way.”
It’s a modern martial art founded in Japan in 1882 by Jigoro Kano, who combined traditional jujutsu techniques with a focus on discipline, mutual respect, and personal growth.
Judo teaches how to use an opponent’s energy and balance to throw, pin, or control them—without relying on brute strength.

Kano Sensei’s way of teaching Judo focused on four main methods used in his dojo:

  • Randori (rahn-doh-ree) – Free practice, where students try techniques with a partner in real time

  • Kata (kah-tah) – Pre-arranged forms that teach the technical and traditional side of Judo

  • Ko (koh) – Lessons or talks where the teacher explains important ideas and concepts

  • Mondo (mohn-doh) – A time for students to ask questions and talk with the teacher to better understand what they’re learning
