Orange County Kodokan (OCK) dojo is one of the oldest, most respected judo dojos in Orange County. With a world class staff of instructors, we have been teaching men, woman, and children the martial art of judo for decades. Turning out a number of national champions and three Olympians, we are extremely proud of our heritage. We are committed to retaining the traditional values that have given us longevity and have helped us develop a respectable reputation. Orange County Kodokan supports charitable non-profit judo organizations through the Orange County Kodokan Judo Foundation, and the Nanka Yudanshakai. If you would like to learn more about our program or are interested in becoming a supporter or sponsor, we invite you to contact us.
