After facing Australia in a pair of exhibitions, Samurai Japan is in Tokyo with two big wins and two nagging questions before the start of the WBC.

Japan will make its Tokyo Dome debut on Saturday against the Japan Series champion Seibu Lions and faces the Central League champion Yomiuri Giants the following day, looking to build upon a decent showing against Australia at Kyocera Dome in Osaka.

Forced to come from behind on consecutive nights, Japan routed the mistake-prone Aussies 8-2 on Tuesday and 11-2 on Wednesday.
