Good idea. Good results, too, as seen by Shinji Kagawa's rise to stardom. He now plays for Manchester United. Takumi Ishizaki is the best Japanese basketball player overseas these days. He plays in Germany (BV Chemnitz 99). The competition is better there, and he benefits from the experience every day.
It's time for more of his basketball-playing compatriots to do the same thing to help them improve as players and be the springboard for the next generation of Japanese basketball, showing that the challenge is well worth it. That the risk of failure is an important step.
Scoring maestro Takuya Kawamura, for example, fits this description perfectly. He can continue to thrive in the JBL or be a force for change by playing far away from home and succeeding. He's young enough (still only 26) to stumble and grow and excel after making necessary adjustments to his game.
