Why Tri-Valley Judo?

Established in 2009, TVJ is a member of USA JUDO, the governing body of American Judo. We pride ourselves in serving the community by providing a means for families and individuals to enjoy Judo as an organized sport or recreational activity.

Tri-Valley Judo is a unique Judo club that trains its “Judoka” (Judo Student) with a unique blend of traditional Kodokan Judo, No-Gi Judo, Competition Judo, Self-Defense Judo and Kosen Judo.  A plethora of strategy, techniques, and training philosophies gathered from our American , Asian and European judo coaches who have coached trained or competed around the world.

Judo Techniques

 Judo, which means "The Gentle Way", is a Japanese martial art based upon the ancient techniques of jujutsu. Dr. Jigoro Kano, President of the University of Education in Tokyo, developed judo in 1882. Dr. Kano, who had studied jujutsu , incorporated the best of these ancient techniques into the new art of Judo. Dr. Kano subsequently founded the Kodokan in Tokyo, Japan as a place to teach his new art.

 Judo is known for its spectacular throwing techniques but also includes numerous techniques for controlling an opponent while on the ground. Judo is often compared to freestyle wrestling and while the two share many techniques, Judo retains many dangerous self-defense maneuvers. A good judoka, one who practices Judo, will first use timing and leverage to bring his opponent off balance and execute a throw. Once the judoka has thrown his opponent to the ground, he will use hold-down techniques, chokes, strangleholds, and armlocks to control and subdue the opponent. If the opponent does not surrender, he will either have his elbow joint dislocated by means of an armlock or will be rendered unconscious with a chokehold.  A judoka first learns "ukemi", the art of falling properly to avoid injury.  All Judo practitioners wear a judogi and a belt. Judo is practiced on mats for safety.

Judo Philosophy

The main principles of Judo are "Minimum Effort, Maximum Efficiency" and "Mutual Welfare and Benefit." The goal of maximum efficiency teaches the judoka to use the least amount of physical strength necessary to throw an opponent. This is accomplished by proper use of technique and timing. The goal of mutual welfare and benefit was an extension of Dr. Kano's belief that Judo could help the individual become a better member of society. Dr. Kano felt that the personal discipline that Judo taught would extend beyond the dojo into daily life and could allow the judoka to become a more productive citizen.

Judo is a sport

In 1964, Judo became the first martial art to be sanctioned as a medal sport in the Olympic Games. Judo competitions are  held throughout the world and is very popular in Europe and Asia. Judo is the second most  participated sport in the world next to soccer.

Other Aspects About Judo

People practice Judo for many different reasons such as exercise, self-defense, a social activity, and for many practitioners, Judo becomes a way of life. But if you ask most judoka why they train Judo, they will say that they practice Judo because it is fun. Judo is a great exercise routine. It promotes flexibility, develops speed and co-ordination, strengthens the cardiovascular system, and promotes balanced muscular development. Many Judo techniques can also be employed as a means of self-defense. The throws and chokes of Judo are particularly effective if one is forced to deal with an assailant.

Judo ranks are awarded for developing proficiency in certain techniques and for regular practice. All judoka begin as white belts. Over time, they may earn a yellow belt, orange belt, green belt, blue belt, three degrees of brown belt, and finally a black belt. 

Etiquette is an important part of the sport of judo. Players are expected to respect their practice partners, opponents, their instructors, coaches, the referees and officials at tournaments.
