With the FIBA World Cup just around the corner, the Japan men's national team will head to China with confidence, but also with some issues that need to be fixed.

The squad played a series of warm-up games against New Zealand, Argentina, Germany and Tunisia in preparation for the World Cup, which kicks off on Saturday. Japan will also face Tunisia in a practice game on Tuesday in Tokyo before departing for Shanghai, its first-round site for the World Cup.

Japan played three contests before full-house crowds at Saitama Super Arena, falling against world No. 5 Argentina and Tunisia while pulling off an upset of Germany. The team posted a victory over New Zealand in its first exhibition earlier this month.
