B.League transitions to new B.Premier league structure

The B.League is transitioning to a new top-tier league structure known as B.Premier for the 2026–27 season. Under this new format, 26 teams will compete in a league consisting of East and West divisions, with the top three teams from each division and two wildcards advancing to the playoffs.

In the East Division, teams such as Chiba J, Gunma, and Ibaraki are noted as significant competitors. Meanwhile, the Shiga Lakes are preparing for the new season by integrating new talent with their existing core players, aiming to reach the playoffs through a blend of new and old roster elements.
