The Kodokan — The Spiritual Home of Judo in the Heart of Tokyo

 
Right next to Tokyo Dome City in Bunkyo Ward — surrounded by a stadium, amusement rides, hotels, and shopping complexes — stands a place that holds a special meaning for judoka around the world.

This is the Kodokan (講道館), the worldwide headquarters of judo, often referred to as “the Mecca of Judo.”

The Kodokan building stands  beside the roller coaster tracks of Tokyo Dome City.

From a Small Tatami Room to a Global Martial Art

The Kodokan was established in 1882 by Jigoro Kano (1860–1938), the educator and martial artist who transformed traditional Japanese jujutsu into modern judo.

What began as a humble 12-tatami training hall eventually grew into a martial art practiced in more than 200 countries and regions worldwide.

Kano was far more than a martial arts master.
As principal of Tokyo Higher Normal School — now part of Tsukuba University — he played a major role in shaping modern physical education in Japan, earning recognition as “the father of Japanese physical education.”

He also became the first Asian member of the International Olympic Committee (IOC) and helped establish the Japanese Olympic Committee (JOC), leaving an enduring impact on international sports culture.

The Mission of Kodokan – Nurturing the Spirit of Judo

Before Kano’s reforms, Japan had numerous independent schools of jujutsu.

By studying and reorganizing their techniques into a unified system while emphasizing ethics and education, Kano transformed martial arts training into a lifelong path of self-development.

Today, the Kodokan functions as much more than a dojo.
It helps establish international standards for judo, trains instructors, supports youth education, promotes research, and encourages cultural exchange.

As a public foundation, it continues to serve as a center dedicated to preserving and nurturing the future of judo.

Judo from Kodokan to the World

Judo is now one of the world’s best-known Olympic sports, and its origins trace directly back to Jigoro Kano and the Kodokan.

The International Judo Federation (IJF) recognizes Kano’s Kodokan as the source of “true judo.”

While the IJF oversees judo as a modern international sport, the Kodokan preserves its traditional philosophy and spirit, and the two organizations work closely together.

Interestingly, tournaments held at the Kodokan differ slightly from Olympic competition rules.
Match duration, scoring systems, and restrictions on techniques may vary, and only white judogi are permitted — colored uniforms are not allowed. This reflects the Kodokan’s dedication to maintaining the traditional character of judo.

Training at Kodokan – Open to Visitors with Experience

The Kodokan welcomes both Japanese and overseas practitioners.

Training on the mats is limited to students enrolled in the Kodokan’s judo school and officially registered members.
Anyone with previous judo experience may apply for membership and participate in regular practice sessions alongside other judoka.

The registration fee is ¥8,000, although it is waived for black belt holders and above. Daily practice costs ¥880.

Reservations are unnecessary, as registration can be completed at the front desk on the same day. Practice sessions are generally held in the evening until around 8:00 p.m.

There are also strict dress rules.
Only white judogi are accepted. Men practice without undershirts, while women wear plain white T-shirts beneath their uniforms.

What to See – The Statue, Museum, and the Dojo’s Energy

Even if you don’t train, the Kodokan is well worth a visit.
Located near Kasuga and Korakuen Stations,a bronze statue of Jigoro Kano welcomes visitors.

The eight-story main building contains the Kodokan Judo Museum on the second floor, which is open free of charge.

Exhibits include early documents, wooden plaques, records of international tournaments, and items related to Kano’s life.
You can even try on a judogi and take a commemorative photo — giving the museum a surprisingly friendly atmosphere amid its solemnity.

From Children to Champions: A Day Inside the Kodokan

The dojo itself occupies the upper floors beginning around the third level.

Although only registered practitioners may enter the training space, visitors are allowed to observe practice sessions from the viewing gallery above, overlooking the broad sea of tatami mats below.

Around 4:00 p.m., children in spotless white judogi begin training.

At first, the atmosphere feels energetic and cheerful, filled with movement, smiles, and laughter. Yet behind the playful mood, every bow and every throw is performed with seriousness and discipline.

By around 6:00 p.m., the atmosphere shifts noticeably.

University students, working adults, experienced practitioners, and even Olympic-level athletes begin arriving, and the dojo fills with the sounds of intense practice and repeated techniques.

Watching from above, visitors can sense Kano’s philosophy still alive within the building — the belief that judo is not simply a combat sport, but a lifelong pursuit of discipline, respect, and personal growth.

A Unique Experience – Staying at Kodokan

One lesser-known feature of the Kodokan is its own accommodation facility.

The Kodokan Hostel is available exclusively for registered members visiting from Japan and abroad for training and study.

Accommodation options range from dormitory-style rooms to private singles and twin rooms, with rates generally between ¥4,400 and ¥16,500 per night.

For many judoka, the opportunity to stay overnight at the birthplace of judo is itself a memorable and meaningful experience.

A Place of Spirit and Respect

For martial arts enthusiasts, the Kodokan is far more than a historic institution.

It remains a living center of discipline, mutual respect, and self-cultivation.

Whether visiting to train, observe, or simply explore the museum, many people are struck by the calm atmosphere and deep traditions preserved within the building.

When visiting Tokyo, stepping inside the Kodokan offers a rare chance to hear the soft sound of feet moving across tatami mats and to witness the quiet beauty of two judoka bowing to one another.

Here, the spirit of judo — “the gentle way” — continues to live on.
