69th Yamanashi Prefecture Junior High School Basketball Championship Tournament: Schedule and Venue Guide

The road to glory for the region’s youngest stars is now set. The 69th Yamanashi Prefecture Junior High School Basketball Championship Tournament is preparing to tip off, bringing together the top middle school talent in Yamanashi, Japan, for a high-stakes battle for prefectural supremacy.

For these athletes, the tournament represents the pinnacle of their junior high careers, blending tactical discipline with the raw energy of youth sports. As the 2026 season unfolds, teams are now focusing on the final stages of preparation before the main bracket begins.

Tournament Structure: The Road to the Main Bracket

Before the spotlight shifts to the main tournament, teams must first navigate a rigorous qualification process. The tournament is structured to ensure that only the most consistent performers reach the final stages.

According to official guidelines from the Yamanashi Prefecture Junior High School Physical Education Federation Basketball Department, the regional representative matches—which encompass the prefectural first and second rounds—take place prior to the main tournament. These qualifying rounds are held within each respective branch, serving as a critical filter that determines which teams earn the right to compete in the championship bracket.

This tiered system ensures that the main tournament remains a concentrated showcase of the prefecture’s elite, rewarding teams that can maintain composure through the grueling regional qualifiers.

The 2026 Main Tournament Schedule and Venues

The main tournament will be contested over three consecutive Sundays, moving from wide-scale opening rounds to a focused finale. The event is spread across several key sports facilities in Yamanashi to accommodate the volume of games and spectators.

Here is the verified schedule for the main tournament:

• May 24, 2026: The action begins at four primary locations: Kose Sports Park Gymnasium, Showa General Gymnasium, Kushigata General Gymnasium, and Shonzan Sports Center.
• May 31, 2026: The competition continues at Showa General Gymnasium, Kushigata General Gymnasium, Futaba Gymnasium, and Shonzan Sports Center.
• June 7, 2026: The tournament reaches its climax, with the final stages hosted at Showa General Gymnasium and Nirasaki Arena.

For those traveling to the events, the governing body is headquartered at the Kofu Municipal Higashi Junior High School in Kofu City (Tokoji 2-8-1), which serves as the administrative hub for the basketball department.

Tracking the Legacy: From 2025 to 2026

While the 2026 bracket is still taking shape, the shadow of last year’s champions looms large. In the 2025 season, the competitive landscape was dominated by two standout programs: Oshihara took the title for the boys’ division, while Fuji Gakuen claimed victory for the girls.

The transition from 2025 to 2026 often sees a shift in dynamics as graduating seniors leave and novel talent emerges. However, the programs that consistently reach the finals, like Oshihara and Fuji Gakuen, typically set the tactical benchmark for the rest of the prefecture.

U15 Federation and Administrative Updates

Parallel to the school-based championships, the Yamanashi Basketball Association’s U15 wing continues to evolve its organizational structure to better support youth development.

Those following the U15 circuit should be aware of a significant digital transition: as of February 16, 2026, the U15 Federation officially migrated to a new homepage. This move was designed to streamline communication and provide more efficient access to tournament data and official announcements.

the federation released critical information regarding 2026 registrations and entries on March 24, 2026. These administrative deadlines are vital for players participating in the broader U15 league and championship ecosystem, ensuring all athletes are properly credentialed before the summer competitive peak.
