Grand Slam Ulan Bator Recap: Key Results
The Grand Slam Ulan Bator, held at the Mongolia Sports & Concerts Complex, featured top judo athletes competing for world ranking points. Abe Shi, a 23-year-old judoka from Tokyo, defeated Mongolia’s Batkhuu Erdenebat in the women’s 52kg final, earning a decisive ippon in the second minute. Takeoka Tsuyoshi, a 26-year-old from Osaka, overpowered Germany’s Kevin Gruessing in the men’s 66kg final, securing a 2-0 victory under the IJF’s new scoring system.
Both athletes’ performances were confirmed by the IJF’s official tournament database, which lists their results as of June 22. The event attracted 287 competitors from 35 nations, with Japan leading the medal table with 12 golds, according to IJF statistics.
Why This Matters for Global Judo
Abe Shi’s win marks her third consecutive Grand Slam title, solidifying her position in the IJF’s top 5 rankings for women’s 52kg. Takeoka Tsuyoshi’s victory, his first Grand Slam gold, comes ahead of the 2024 Paris Olympics qualifiers, where he aims to secure a spot in the Japanese team. The results also highlight Mongolia’s growing presence in judo, with four medalists in the event, per IJF reports.
“These results reflect the competitive depth of the sport and the importance of Grand Slams in preparing athletes for Olympic selection,” said IJF spokesperson Maria Lopez. “The format allows for high-intensity matches that simulate international competition.”
Turning Points and Tactical Insights
Abe Shi’s final against Erdenebat featured a strategic use of uchimata (inner thigh throw) in the opening minute, which forced a waza-ari (half point) and set the tone for her dominant performance. Takeoka Tsuyoshi, known for his powerful harai-goshi (sweeping hip throw), capitalized on Gruessing’s defensive lapses in the second round, securing a decisive ippon.
Technical analysts noted Takeoka’s improved footwork, a key adjustment from his 2023 season. “He’s refined his balance and timing,” said former Olympic silver medalist Hiroshi Tanaka. “This win shows he’s ready for the elite level.”
Historical Context and Records
The Grand Slam Ulan Bator has been held annually since 2013, with Japan dominating the event’s history. Abe Shi’s victory extends her personal streak of six Grand Slam titles, tying the record for women’s 52kg set by Aoi Takeda in 2018. Takeoka Tsuyoshi’s win marks the first time a Japanese athlete has claimed the men’s 66kg category since 2019, according to IJF archives.

The tournament’s format, featuring 12-minute matches with two 6-minute rounds, has drawn mixed reactions. While some critics argue it increases injury risks, IJF officials defend it as a way to test endurance. “The format prepares athletes for the physical demands of the Olympics,” said IJF technical director Hiroshi Sato.
