Open Weight Supremacy: 41st Empress Cup All Japan Women’s Judo Championships Set for Yokohama
The pinnacle of domestic women’s judo returns to Kanagawa this weekend as the All Japan Women’s Judo Championships, widely known as the Empress Cup, prepares for its 41st edition. Scheduled for Sunday, April 19, 2026, the tournament will convene at the historic Yokohama Budokan, bringing together the nation’s elite practitioners to compete in the most challenging format of the sport: the open weight category.
For the global judo community, the Empress Cup represents more than just a national title. It’s a grueling test of technique over power, where athletes from various weight classes must navigate a bracket that ignores traditional divisions. In a sport where weight advantages are often decisive, the open weight format forces a reliance on superior kuzushi (off-balancing) and tactical precision.
Event Logistics and Schedule
The tournament is organized by the Kodokan and the All Japan Judo Federation, with the Kanagawa Judo Federation serving as the primary supervisor. The event is supported by a wide array of partners, including the Japan Sports Agency, NHK and the City of Yokohama.
Spectators and analysts should note the following timing for the event on April 19:
- Doors Open: 10:00 AM local time
- Competition Start: 11:00 AM local time
- Venue: Yokohama Budokan (2-9-10 Okina-cho, Naka-ku, Yokohama, Kanagawa Prefecture)
The Yokohama Budokan remains a cornerstone for martial arts in Japan, providing a high-pressure atmosphere that mirrors the intensity of international championship stages.
The Path to the Tatami: Qualification and Field
Entry into the Empress Cup is strictly regulated, ensuring that only the top-tier talent in Japan takes the mat. The field is composed of two primary groups: recommended athletes and regional qualifiers.
Recommended Athletes
The federation grants automatic entry to a select group of elite competitors to ensure the highest level of competition. This includes the previous year’s winner and runner-up, as well as the gold medalist from the 2025 World Judo Championships.
Regional Qualifiers
Beyond the recommended seeds, 34 athletes are selected through a rigorous regional qualification process. The distribution of these spots reflects the density of competitive judo hubs across Japan:
| Region | Number of Selected Athletes |
|---|---|
| Tokyo | 8 |
| Kanto | 7 |
| Kinki | 5 |
| Hokkaido | 2 |
| Tohoku | 2 |
| Hokushinetsu | 2 |
| Tokai | 2 |
| Chugoku | 2 |
| Shikoku | 2 |
| Kyushu | 2 |
To maintain the integrity of the bracket, the All Japan Judo Federation has strict rules regarding absences. Although recommended athletes are not replaced if they withdraw, regional vacancies are first filled by the respective region. If a region cannot provide a replacement, the host region (Kanto) steps in to fill the slot.
Eligibility and Standards
The Empress Cup is open to athletes who hold Japanese nationality and are registered with the All Japan Judo Federation for the current year. In a testament to the depth of Japanese judo talent, eligibility extends to students as young as the second year of middle school, provided they meet the registration requirements.
For regional qualifiers, athletes must demonstrate a genuine connection to their represented area, including residency, employment, or enrollment in an educational institution within that specific region.
What to Watch: The Open Weight Dynamic
The defining characteristic of the All Japan Women’s Judo Championships is the absence of weight classes. This creates a unique strategic landscape. Smaller, more agile fighters must rely on speed and precision to overcome the raw strength of heavier opponents, while the heavier athletes must maintain the stamina and mobility to handle faster attackers.
Historically, this tournament serves as a critical barometer for the national team’s health and a proving ground for emerging talent. As it blends established world champions with hungry regional qualifiers, the bracket often produces significant upsets that shift the hierarchy of Japanese judo.
Note for international viewers: The open weight format is a rarity in modern Olympic judo, making the Empress Cup one of the few remaining venues where the “pure” form of the sport—regardless of size—is celebrated on a national stage.
How to Follow
