Kaisei High School Clinches 11th Consecutive Title in Shimane Prefectural Judo Championships

The 64th Shimane Prefecture High School General Athletic Tournament opened on Friday, May 29, 2026, with a dramatic display of athleticism that underscored the regional dominance of Kaisei High School. In a tournament defined by high-stakes competition, the Kaisei boys’ judo team secured their 11th consecutive team title, marking their 29th championship victory overall.

The path to victory was far from routine. In a tense final against Hirata High School, the match remained deadlocked, eventually forcing a “daihyo-sen”—a decisive representative match to break the tie. Kaisei captain Shota Yamazaki ultimately delivered the winning performance, overcoming a notable physical size disadvantage to secure an ippon, effectively ending the contest and sealing the championship for his squad.

Tournament Context and Performance

The tournament, which serves as a critical milestone for high school athletes in the region, saw seven different sports conduct their opening sessions on the first day of the preliminary schedule. While the boys’ judo division provided the dramatic climax of the afternoon, the girls’ bracket saw Izumo Nishi High School claim their second consecutive title and 18th overall championship.

The intensity of the competition was reflected in the individual weight class results, where even top-seeded programs faced significant resistance. Official tournament data from the event highlighted the grueling nature of the brackets, with several athletes across various weight classes, including the 60kg, 66kg and 81kg divisions, seeing their runs cut short in early-round matches. For many of these student-athletes, the Shimane Prefectural tournament represents the culmination of months of rigorous training and the primary gateway to higher-level competition.

Beyond the Mats: Multisport Success

The first day of the tournament was not limited to the judo mats. The event featured broad participation across 13 distinct athletic disciplines, including basketball, track and field, and sumo. In the cycling events, Rio Takahashi of Izumo Technical High School emerged as a standout performer, sweeping four distinct events, including the sprint and the 1000-meter time trial.

On the women’s side of the cycling competition, Yuki Edo, also representing Izumo Technical, mirrored this success by capturing titles in three events, including the sprint. These results further highlight the depth of athletic talent currently competing within the Shimane high school sports circuit.

Looking Ahead

As the initial phase of the 64th Shimane Prefecture High School General Athletic Tournament concludes, the focus shifts immediately to the second day of competition. Organizers have confirmed that the schedule for the second day includes 13 sports, with continued action in basketball, track and field, and sumo, among others.

For Kaisei High School, the victory provides both momentum and a target on their backs as they look toward future regional and national qualifications. While the celebrations in the Kaisei camp are well-earned, the rapid pace of the tournament ensures that the focus for all participating schools remains on the upcoming rounds of the preliminary schedule.
