Osaka Evessa: Japan’s First Pro Basketball Champions
Osaka Evessa: Japan’s First Pro Basketball Champions
Before the B.League existed, one club dominated Japan’s first professional basketball league — winning the very first title and then two more. Osaka Evessa are where the pro game’s story begins.
The Osaka Evessa are a B.League club from Osaka with a unique claim: they were the first champions of Japanese professional basketball. In the original bj league, they won the inaugural 2005–06 title and then three in a row (2005–06, 2006–07, 2007–08). They’ve yet to add a title in the modern B.League era, but their place in history is permanent. They play at Okini Arena Maishima and have been admitted to B.LEAGUE PREMIER for 2026–27.

1. Who Osaka Evessa are
The club that opened the professional era.
The Osaka Evessa represent Osaka, Japan’s second city, and play at Okini Arena Maishima.1 They are one of the most historically significant clubs in the country — the team that won the first championship of Japan’s first fully professional basketball league. ⚠ Standings, arena plans and rosters change — check the latest.
2. The first dynasty
When the bj league — Japan’s first professional basketball league — launched in 2005, the Evessa were its first dominant force. They won the inaugural 2005–06 championship and made it three titles in a row through 2007–08, the original dynasty of the Japanese pro game.1 For anyone tracing how professional basketball took root in Japan, Osaka is the starting point.
3. A historic name in the modern era
The picture since has been humbler. After the bj league and NBL merged to form the B.League in 2016, the Evessa have competed in the top flight without recapturing their early-era dominance, and a B.League championship has so far eluded them.1 Their Okini Arena Maishima home is set for redevelopment as the club steps up for the new top division. They have been admitted to B.LEAGUE PREMIER for 2026–27. ⚠ Arena timelines and league results change — confirm the latest.
