Rebound (1994)

Blurb:
The continuing adventures of Nate Torres, a teenager who always thought of himself as a quitter - until he entered the world of street basketball. Sapporo has become overrun with thousands of student athletes all thirsting for the chance to come out victorious in Japan’s National Basketball Championships. Representing Tokyo in the competition, The Jonan High School varsity basketball team has beat the odds in getting there and won’t leave without the pennant. But they’ll soon learn that playing against the kids in their neighborhood pales in comparison to the kind of game the thugs and pros at the championships will give them. Right off the plane, they find themselves staring down the nostrils of the Kyan Marine Industry team, a burly collection of tanned rough necks who plan on knocking off any team that stands in their way. But Jonan has heart, they have determination and, with a little luck, this team might just do Tokyo proud ... as long as they don’t get distracted by the tourists spots, the shopping and the girls schools!
