Guide to Judo｜Martial Arts in Japan

How did judo, originating from Japan’s samurai and jujutsu traditions, transform into an Olympic sport beloved worldwide? This concise guide uncovers its journey, rules, and global impact, emphasizing judo’s blend of physical skill and mental discipline, underscoring the martial art’s core values of respect and sportsmanship.

History and Evolution of Judo

Origins and Evolution of Judo

Judo, a martial art recognized globally and part of the Olympic Games, has its roots deeply embedded in Japan’s history. Originating from jujutsu, a close-combat technique of the samurai during the Kamakura and Edo periods, judo was formalized in 1882 by Kano Jigoro. Combining physical discipline with mental strategy, judo emerged from the ancient sumo tradition, with historical mentions dating back to texts like the Kojiki (712) and Nihon Shoki (720). The transition from the Edo to the Meiji period marked a critical juncture for martial arts, with judo preserving the essence of samurai combat techniques for the modern era.

Founding of Modern Judo

Kano Jigoro, pivotal in judo’s development, aimed to amalgamate the best elements of various jujutsu styles into a comprehensive martial art. By 1882, at merely 21 years old, Jigoro established the first judo dojo in a Tokyo temple, laying the foundation for what would become a global sport. Despite starting with only nine students, his dedication to promoting judo’s physical and moral benefits helped the discipline flourish. A significant moment in judo’s history occurred during Jigoro’s travels to Europe, where he demonstrated judo’s efficacy and philosophy through a spontaneous act of self-defense, underscoring the sport’s balance of strength and consideration for the opponent.

Judo on the Global Stage

Achieving international recognition, judo was introduced to the Olympic Games in Tokyo in 1964, with weight classes determining the competitors. The inclusion of judo in the Olympics was a milestone, highlighting the sport’s global appeal beyond its Japanese origins. By 1992, women’s judo became an official Olympic sport, further cementing its place on the world stage. Today, the International Judo Federation boasts 204 member nations, with Europe being a significant hub for judo enthusiasts. Japan continues to promote judo internationally through educational programs and the donation of equipment, striving to share this martial art with the world.

Rules of Judo

Judo Match Structure and Scoring

Judo matches take place on a square mat ranging from 8 to 10 meters on each side, observed by a head referee on the mat and assisted by two sidelines referees. Outside the mat, officials including a scoring, time, and recording official, alongside a judgment referee, ensure the match’s smooth execution. A standard judo match lasts four minutes, with competitors employing 32 grappling (katame-waza) and 68 throwing techniques (nage-waza) to score. The highest score, an ippon, is awarded for a perfect throw or a submission via grappling. Alternatively, wazaari points are given for lesser throws or holds, with two wazaari equaling an ippon to win the match.

Winning Techniques and Penalties

Victory in judo can be achieved through an ippon, either by executing a flawless throw that lands the opponent on their back, securing a submission through grappling, or holding the opponent on the mat for 20 seconds. If the attacker performs a technique that doesn’t fully meet the ippon criteria but is significant, a wazaari is awarded. Matches also involve penalties for infractions such as passivity, leaving the mat area, or employing illegal techniques, with three shido penalties leading to disqualification. In case of a tie, the Golden Score rule applies, extending the match until a decisive point is scored.

Etiquette and Respect in Judo

Respect and manners, or reihou, play a crucial role in judo, reflecting the sport’s emphasis on mutual respect among practitioners. Competitors demonstrate this by bowing at approximately a 30-degree angle before and after each match, as well as when entering and exiting the mat. This practice highlights judo’s cultural roots and the importance of etiquette in martial arts, reinforcing the values of humility and respect in every aspect of the sport.

Uniform of Judo

The components of a judo costume are an obi (belt), shitabaki (pants), and joi (top). While one rival is dressed in white, the other is dressed in blue. Although both competitors always wore white, the International Judo Federation formally adopted blue judogi in 1997.

The contestants are simpler for onlookers to discern because to this hue. Additionally, it facilitates the process of identifying rivals during katame-waza (grappling tactics). The 2000 Sydney Olympics saw the introduction of blue judo suits, which have since spread to other major events like the World Championships.
