Seiko Watanabe Claims Empress’s Cup Title in Historic Debut at 41st All-Japan Women’s Judo Championships
Yokohama, Japan – April 19, 2026 – In a stunning upset that echoed through the Yokohama Budokan, first-time entrant Seiko Watanabe captured the Empress’s Cup at the 41st All-Japan Women’s Judo Championships, becoming the inaugural open-weight queen to emerge from the 63-kilogram division. The victory, secured through a unanimous decision by flag in the final, marked a historic milestone in Japanese women’s judo as Watanabe, competing in just her first national championship appearance, defeated a field of seasoned veterans to claim the sport’s most prestigious domestic title.
The triumph represents more than just a personal breakthrough for the 24-year-old judoka from Saitama Prefecture. Watanabe’s win continues a remarkable trend in Japanese women’s judo where athletes from lighter weight classes have increasingly dominated the open-weight category in recent years, showcasing the technical precision and adaptability that defines modern judo competition. Her path to victory included victories over established competitors through a combination of shoulder throws, reverse turns, and armbar techniques that demonstrated both her tactical intelligence and physical resilience.
According to the official match report published by eJudo, the tournament’s primary digital platform, Watanabe’s final bout was characterized by controlled aggression and technical superiority. The report noted that she maintained consistent pressure throughout the match, effectively neutralizing her opponent’s attacks while creating scoring opportunities through precise gripping and movement. The unanimous decision by the referee panel – all three judges signaling victory with white flags – underscored the clarity of her performance in what proved to be a tightly contested final.
The Empress’s Cup, first awarded in 1948, remains the pinnacle of achievement in Japanese women’s judo, traditionally reserved for athletes who have demonstrated sustained excellence across multiple weight classes and international competitions. Watanabe’s achievement as a first-time participant breaking through to claim this honor places her in rare company among Japanese judoka, joining the ranks of athletes like Ryoko Tani and Mao Kobayashi who achieved similar feats earlier in their careers.
Throughout the tournament, Watanabe displayed a versatile fighting style that adapted to various opponents’ strengths. In early rounds, she utilized her signature shoulder throw (seoi-nage) to establish early advantages, while later matches saw her employ reverse turns (ura-nage) and arm entanglements (juji-gatame) to counter more defensive opponents. Her ability to transition seamlessly between techniques based on her opponent’s posture and grip fighting proved decisive in several close contests.
The victory also highlights the continued depth of talent within Japan’s women’s judo program, which has produced multiple Olympic and World Championship medalists in recent years. Watanabe’s emergence as a national champion at such an early stage in her senior career suggests she could become a fixture on Japan’s international team for years to come, particularly as the nation prepares for upcoming continental and global competitions.
For Watanabe, the Empress’s Cup title represents both validation of years of dedicated training and a platform for future aspirations. In post-competition remarks covered by Japanese media outlets, she expressed gratitude to her coaches and training partners while emphasizing her commitment to continued improvement. The win also earns her automatic consideration for Japan’s national team selections in upcoming international tournaments, where she will likely compete in both her weight class and open-weight divisions.
As the judo world turns its attention to the upcoming Asian Games and World Championships, Watanabe’s performance at the Empress’s Cup serves as a reminder of the sport’s enduring capacity for surprise and excellence. Her journey from 63-kilogram specialist to open-weight champion in a single tournament exemplifies the technical mastery and mental fortitude required to succeed at judo’s highest levels, offering inspiration to athletes across weight classes who aspire to transcend traditional divisions through skill and determination.
The 41st edition of the All-Japan Women’s Judo Championships concluded with Watanabe’s victory adding another chapter to the rich history of the Empress’s Cup, a trophy that has symbolized excellence in Japanese women’s judo for over seven decades. Her achievement ensures that the legacy of the tournament continues to evolve, reflecting the changing dynamics of competitive judo while maintaining its status as the ultimate test of skill, heart, and championship pedigree in Japan.
