Kazuma Okamoto has spent all season showing why many think he could be one of Japan's next great slugging stars.

Now he'll get to show it against some of MLB's best.

Okamoto, the Yomiuri Giants' 22-year-old cleanup hitter, was given his first call-up to the Samurai Japan top team on Wednesday, when manager Atsunori Inaba revealed his roster for next month's Japan All-Star Series, which will pit the national team against an MLB All-Star squad.
