Kumamoto Prefecture is set to host the 8th All Japan Adult Basketball Premium Championship, a premier amateur basketball tournament, from March 7th (Saturday) to March 9th (Monday), 2026. The competition will take place at the Kumamoto Prefectural General Gymnasium, also known as the Nurs Power Arena, in Kumamoto City. This event promises a high level of competition as teams from across Japan vie for the championship title.
The Takamatsunomiya Memorial Cup, as the championship is officially known, has become a cornerstone of the Japanese amateur basketball scene. The tournament brings together top teams from various leagues and qualifying events, showcasing the depth of talent outside of the professional ranks. This year’s competition builds on the success of the 7th edition, held in Aomori City in 2025, which featured 42 teams – 28 men’s and 14 women’s squads – representing a diverse range of regional and league affiliations.
Tournament Format and Participating Teams
The championship will follow a knockout format, meaning teams will be eliminated after a single loss. Notably, there will be no third-place match, intensifying the pressure on each game. The 2025 tournament included teams from the SBL-SB2 league, participants from the All Japan Adult Championships, and the newly established SBL-SB1 teams, and it is expected that the 2026 edition will continue this trend.
Whereas the specific team breakdown for the 2026 tournament hasn’t been released, the 2025 event provided a regional snapshot of participation. The men’s competition saw representation from Hokkaido (1 team), Tohoku (2 teams), Kanto A (3 teams), Kanto B (3 teams), Tokai/Hokushinetsu (3 teams), Kinki (3 teams), Chugoku/Shikoku/Kyushu (3 teams), SB-1 (8 teams), and the All Japan Adult Championship (2 teams). The women’s competition featured teams from West Japan (2 teams), East Japan (4 teams), SB-1 (6 teams), and the All Japan Adult Championship (2 teams). Details of the 2025 tournament structure offer insight into the likely format for the upcoming competition.
