Under the previous format, the league winners played against teams from western Japan in the Koshien Bowl.

In 2024, the new format allows the top three schools to compete in the Koshien Bowl Tournament.

Other participating schools in the tournament are the top three schools from the Kansai Collegiate American Football League Division 1, and the winners of each league from Tohoku, Hokuriku, and Chugoku-Shikoku.

The winners of each conference would then play in the Azuma Bowl, to determine league champion.

Starting in 2014, the league switched to a two division format, the Top 8 and Big 8.
