Japan manager Tatsunori Hara has settled on a WBC roster. Here it is:
(SI has the AP article as well)
Notable departures are Nobuhiko Matsunaka (achilles problem), Kenta Kurihara (affected by elbow surgery last year), Toru Hosokawa (right shoulder pain), Tsuyoshi Wada, and Takayuki Kishi. Health reasons were not cited for Wada and Kishi.
Overall, the roster looks pretty good to me, though it's somewhat short on power.The inclusion of Yoshiyuki Kamei makes no obvious sense to me, but I could see him as a defensive replacement/pinch runner. The only other questionable pick I see is Shunsuke Watanabe. He's been hit or miss in NPB, and as I recall he wasn't that great in the 2006 WBC.
