The dominant Oka Gakuen High School girls basketball program added another Winter Cup trophy to its mantle with an 89-65 win over Tokyo Seitoku University High School in the All-Japan High School final at Tokyo Metropolitan Gymnasium on Monday.

The Aichi Prefecture School won its second straight championship and 23rd overall. The girls powerhouse has won nine of the past 14 titles at the storied event.

Oka senior Amaka Susan Okonkwo was too big and too strong for Tokyo Seitoku. The 186-cm Nigerian center set a single-game record for points scored in a girl’s final with 53. She also grabbed 21 rebounds. Azusa Asahina chipped in with 16 points.
