Yamaguchi prefectural qualifiers for Winter Cup high school tournament open Oct. 31

The Yamaguchi prefectural qualifiers for the National High School Basketball Championship, known as the Winter Cup, open October 31. Under this system, high schools that win their prefectural qualifiers advance to the national tournament, and the Yamaguchi event decides which teams earn those spots.

The Winter Cup is the national winter tournament for high school basketball. It is held every year in late December in Tokyo and is organized by the Japan Basketball Association (JBA), with the National High School Athletic Federation as co-host. In 2025, 60 boys' teams and 60 girls' teams took part.

Only high schools that win their prefectural qualifiers can compete in the national tournament. The number of schools that can advance differs by prefecture, so the results of the qualifiers directly determine the national field, which gives each prefectural tournament its significance.

Qualifiers are generally held in stages, moving from district tournaments to prefectural tournaments. Most are single-elimination formats, and teams that lose are out of the tournament. For that reason, each game carries great weight.

High school basketball is played by students across Japan, mainly in school athletic clubs. For high school athletes, the Winter Cup is the stage where the year's efforts come together, and the prefectural qualifiers are the entrance to it.

The key point to watch is which high schools will earn spots in the national tournament once the event opens. Interest in high school basketball within the prefecture is expected to focus on when the qualifiers for the national tournament are decided.
