Japan B. LEAGUE restructuring and launch

Overview

The B. LEAGUE has officially entered its ‘B. LEAGUE PREMIER’ era following a major restructuring known as ‘B. Innovation’. The new format features a tiered system consisting of B Premier, B One, and B Next, involving a total of 55 clubs competing through May 2027.

The inaugural B Premier season debuted on September 22, 2026, with a symbolic opening match at TOYOTA ARENA TOKYO between Alvark Tokyo and the Ryukyu Golden Kings, mirroring the league’s first game from ten years prior. In the opening two-day series, the teams split the results: Alvark Tokyo won the first game 84-73, while the Ryukyu Golden Kings secured their first B Premier victory in the second game with a score of 85-74.

This reorganization maintains strict professional standards, including revenue targets, minimum attendance levels, and the requirement for arenas with at least 5,000 seats. To ensure competitive balance, the league utilizes a salary cap between 500 million and 800 million yen and a ‘star player clause.’ Additionally, ‘on-the-court free’ rules allow teams to field up to three foreign players simultaneously. While the league’s market size remains under 100 billion yen, it continues to focus on regional engagement and rising competitive levels.
