Where judo becomes a test of soul, not size.
Every April 29, at the heart of Tokyo, the Nippon Budokan transforms into a sacred stage. The All Japan Judo Championship (全日本柔道選手権大会) is not just a competition—it’s a living testament to the purest form of Japanese judo.
In this arena, there are no weight divisions, no separation by size or power—only skill, balance, and the essence of the martial spirit.
The Day, the Place, and the Tradition
The championship takes place on April 29, known in Japan as Showa Day (昭和の日)—a national holiday celebrating Emperor Hirohito, a historical supporter of the martial arts.
Its venue, the Nippon Budokan, is far more than a stadium. Built for the 1964 Tokyo Olympics, it stands as the symbolic home of Japanese budo—a place of silence, focus, and discipline.
Inside, the atmosphere is solemn. No loud music, no flashing lights, no entertainment. Only the rhythmic sound of bare feet and judogi fabric brushing the tatami. Every bow, every movement feels like part of a ceremony that connects generations of warriors.
No Weight Classes – The Essence of Openweight Judo
What makes the All Japan Judo Championship unique is simple yet profound: there are no weight classes.
It is an openweight competition, where judoka of every size face each other on equal terms. A 65-kilogram technician may stand against a 120-kilogram powerhouse. Victory comes not from size, but from timing, precision, and the ability to use one’s energy with intelligence.
This embodies the ideal of Jigoro Kano, the founder of judo, who taught: “Maximum efficiency with minimum effort” (seiryoku zenyo).
At the All Japan, that philosophy comes alive on the tatami.
Every throw, every counter, every ippon is a reminder that true judo transcends physicality—it’s about mastery of balance, mind, and moment.
From 1930 to Today – Nearly a Century of Legacy
The All Japan Judo Championship was first held in 1930, born from the desire to find the “true champion” of judo—someone whose mastery stood beyond size or strength.
Except for the wartime years, it has been held every year, maintaining its original spirit for nearly a century.
After judo became an Olympic sport in 1964, the All Japan Championship remained a bastion of tradition. While the rest of the world moved toward standardized rules and weight classes, Japan preserved this sacred arena where technique still reigns supreme.
Winning this title is not just about athletic achievement—it’s about embodying the soul of budo.
The Road to Qualification
Only 48 athletes earn the right to compete each year. Qualification comes through regional championships and special invitations from the All Japan Judo Federation (AJJF).
Most competitors come from elite university teams, police academies, or the Japanese Self-Defense Forces—where judo remains a cornerstone of physical and mental training.
Just qualifying is considered an honor. Many judoka regard their appearance at the All Japan as the pinnacle of their careers. It’s a competition that doesn’t build reputations—it crowns them.
Rules, Format, and Spirit of Competition
The tournament follows a single-elimination format, with matches lasting five minutes. In case of a draw, the fight continues in golden score, with no time limit—until an ippon or penalty decides the winner.
This creates tension and drama that few other tournaments can match. The absence of weight divisions makes each contest unpredictable, pushing athletes to rely on precision, adaptability, and willpower.
A smaller judoka might overcome a heavier opponent through pure technique—a living example of judo’s timeless truth: “Gentleness controls strength.”
Legends of the All Japan Judo Championship
Throughout its history, the All Japan Championship has produced some of the greatest names in judo:
-
Yasuhiro Yamashita – Nine consecutive titles (1977–1985). The embodiment of judo’s ideal balance of strength and spirit.

In Japan, to win the All Japan Judo Championship is to etch one’s name into the history of budo. It’s not just a victory—it’s an initiation into legend.
The Women’s All Japan Championship
Since 1983, Japan has also hosted the All Japan Women’s Judo Championship, held under the same openweight format.
While less internationally known, it holds immense prestige within Japan. Champions like Ryoko Tani, Mami Umeki, and Akira Sone have all risen through its ranks, proving that the spirit of judo knows no gender or size.
Symbolism and Cultural Meaning
The All Japan Judo Championship is a mirror of Japanese cultural values: discipline, humility, perseverance, and respect.
It is more than sport—it is a ceremony of mastery, a meditation on what it means to confront oneself through combat.
In a world where entertainment often overshadows authenticity, Japan preserves this event as a quiet monument to budo.
The crowd doesn’t shout; they watch in silence. Every bow is sincere, every ippon carries weight. The focus is not on spectacle, but on truth.
Why It Still Captivates the World
Even though it offers no Olympic ranking points or international medals, the All Japan Judo Championship remains the most prestigious domestic event in Japanese judo.
To compete at the Nippon Budokan on April 29 means one has reached the summit of both physical skill and spiritual maturity.
For the audience, it’s a chance to witness “pure judo”—a reminder of what this martial art was meant to be before it became a sport.
For the athletes, it’s a test of heart. And for the world, it’s proof that the ancient ideals of judo—honor, harmony, and humility—still live on in modern Japan.
Conclusion
The All Japan Judo Championship is not merely a tournament. It is a living ritual, a confrontation between strength and serenity, between tradition and time.
It is where the philosophy of Jigoro Kano still breathes through every throw and every bow.
Each year, as the crowd rises and the tatami falls silent once more, a quiet truth lingers in the air:
True strength has no weight—it has spirit.
