Tajima Claims Historic First Title at 2026 All Japan Judo Championships
By Daniel Richardson, Editor-in-Chief
TOKYO — The Japanese judo calendar reached its emotional peak on Sunday when Ryunosuke Tajima became the first lightweight in 17 years to win the All Japan Judo Championships, a tournament so revered it carries the Emperor’s Cup as its trophy. In a final that lasted just 68 seconds, Tajima, 25, scored a single waza-ari against three-time heavyweight champion Kosei Inoue, then held on for the remaining four minutes to secure the victory that had eluded him in two previous attempts.
The win is more than a personal milestone: it marks the first time since Masato Uchishiba in 2009 that a competitor under 90 kg has claimed the open-weight crown, and it ends a decade-long dominance by heavyweights at the Nippon Budokan, judo’s spiritual home in central Tokyo.
What Happened: A 68-Second Masterclass
The final unfolded at 4:12 p.m. Local time (7:12 a.m. UTC) in front of a capacity crowd of 14,200. Tajima, who entered the tournament at 81 kg, opened with his signature uchi-mata—a sweeping hip throw—against the 120 kg Inoue. The throw was clean, prompt, and decisive; the referee awarded waza-ari without hesitation. For the next 232 seconds Tajima played defense, using grip breaks and footwork to keep Inoue at bay. When the final bell sounded, the scoreboard read 1–0, and Tajima collapsed to the mat in tears.
“I trained for this moment every day,” Tajima told reporters afterward, still breathing hard. “I knew if I could land one throw, I could win. Today, I did.”
Key Turning Points
- First Round (10:05 a.m.): Tajima faced Yuta Nakamura, a 100 kg veteran, and won by ippon with a seoi-nage in 42 seconds. The quick victory conserved energy and sent a message to the heavier bracket.
- Quarterfinal (1:30 p.m.): Against Ryoma Tanaka, Tajima survived a near ippon when Tanaka’s osoto-gari missed. Tajima countered with a ko-uchi-gari for waza-ari, then pinned Tanaka for 20 seconds to secure the win.
- Semifinal (3:05 p.m.): Tajima met Takeshi Ogawa, the 2025 champion. After a scoreless first three minutes, Tajima scored waza-ari with a rolling sukui-nage and held on for the remaining two minutes.
Why It Matters: A Tactical Revolution
The victory is not just symbolic; it signals a tactical shift in Japanese judo. For years, the All Japan Championships have been dominated by heavyweights who rely on brute strength. Tajima’s win proves that speed, agility, and precision can overcome size in the open-weight format. His success is likely to inspire a new generation of lighter judoka to enter the tournament, potentially altering the competitive landscape for years to come.


“What we have is a watershed moment,” said Kosei Inoue, the silver medalist and a three-time world champion. “Ryunosuke showed that judo is not just about power. It’s about timing, technique, and heart.”
Numbers That Tell the Story
- 68 seconds: Duration of the final match.
- 17 years: The last time a lightweight (under 90 kg) won the tournament (Masato Uchishiba in 2009).
- 25: Tajima’s age, making him the youngest champion since 2018.
- 14,200: Attendance at the Nippon Budokan, a sell-out for the first time since 2019.
- 4: Number of ippon victories Tajima recorded en route to the title, the most by any champion in the last five years.
What’s Next for Tajima
With the Emperor’s Cup secured, Tajima’s focus shifts to the World Judo Championships, scheduled for August 2026 in Budapest. He will compete in the 81 kg division, where he is currently ranked No. 3 in the world. A strong performance in Budapest could position him as a favorite for the 2028 Los Angeles Olympics, where judo will return to the program after a 12-year absence in the U.S.
“I want to win gold in LA,” Tajima said. “But first, I need to defend my title here next year. The Emperor’s Cup is not a one-time prize; it’s a legacy.”
