B.LEAGUE Revenue Hits 101.3 Billion Yen; Alvark Tokyo Reaches 9.24B

For the first time, the B.League has surpassed 100 billion yen in total operating revenue, reaching 101.3 billion yen for the 2025–26 season. This milestone represents a fivefold increase in the league’s business scale over its ten-year history, according to official figures released on October 13. Alvark Tokyo led all clubs with a record-breaking 9.24 billion yen in revenue, fueled by the integration of its home venue, TOYOTA ARENA TOKYO.

League-wide growth across ten seasons

The B.League’s financial expansion reflects a broader trend of growth across Japan’s professional basketball landscape. In the 2025–26 season, the combined operating revenue for the league and its 55 clubs across B1, B2, and B3 divisions reached 101.3 billion yen, a significant jump from the 20.1 billion yen recorded in the league’s inaugural season. Total attendance, encompassing regular season games, playoffs, and the All-Star event, rose to 6.12 million, a 9.9 percent increase from the previous year. B.League Commissioner Shinji Shimada noted that this growth is largely the result of individual club efforts as they prepare for the “B.Innovation” league restructuring, emphasizing that the gains were achieved without direct league-imposed constraints on business operations.

Alvark Tokyo’s record-setting revenue

Alvark Tokyo achieved a club-record 9.24 billion yen in operating revenue, approximately 2.5 times higher than its previous year’s performance. A central driver of this growth was the debut of TOYOTA ARENA TOKYO in the autumn of 2025. By managing the club and the arena as a single entity, Alvark Tokyo significantly increased its “other” revenue category—which includes sponsorship fees, food and beverage sales, VIP hospitality, and venue rental income—from 2.3 billion yen to 5.03 billion yen. Commissioner Shimada highlighted that while the new arena provides a major financial platform, the growth is fundamentally anchored in the club’s overall development and core basketball business, noting that further revenue potential exists as the organization continues to mature.

Top-earning clubs and venue impact

The financial rankings for the season illustrate the competitive landscape of the B.League, with clubs operating their own venues occupying the top spots. Following Alvark Tokyo, Chiba Jets recorded 5.9 billion yen in revenue, Utsunomiya Brex followed with 4.04 billion yen, and Ryukyu Golden Kings reported 3.86 billion yen. Commissioner Shimada specifically highlighted Utsunomiya Brex for their performance despite operating out of an existing facility rather than a new, dedicated arena. Describing their financial success as “extraordinary,” the Commissioner suggested that if Utsunomiya were to develop a modern arena, their revenue potential could see even greater growth.

Financial milestones and league data

The 90.4 billion yen in combined operating revenue for all 55 clubs represents a 26.8 percent year-over-year increase. These figures were confirmed in the league’s official summary of club financial results for the 2025 fiscal year. The sustained upward trajectory in both attendance and commercial revenue follows years of league-wide initiatives aimed at meeting the stricter licensing and participation standards required for the upcoming B.League restructuring.
