Tsuyoshi Nishioka, formerly of the Chiba Lotte Marines, signed a three year deal with the Minnesota Twins last week. Nishioka is the first player that I'm aware of to sign with a US team that had a draft pick card in one of BBM's Rookie Edition sets - he was card #70 in the 2003 Rookie Edition set. His BBM rookie card was #304 in the 2003 1st Version set. His first Calbee card appears to be #019 from the 2005 set. He appears in the BBM All Star sets from 2005-2008 and 2010 and the 2005 and 2010 Nippon Series sets. He was a member of Japan's National Team for both the 2006 World Baseball Classic and the 2008 Olympics, so he appeared in at least one of Upper Deck's WBC sets in 2006 (Inaugural Images) as well as BBM's 2008 Olympic team set. As always, this is not meant to be a comprehensive list, merely some highlights.
Here's some cards:
From top to bottom, 2003 BBM Rookie Edition #70, 2006 BBM Marines #M44, 2007 Calbee #038, 2008 BBM Japan National Team #JPN21, 2009 BBM 1st Verion "Game Masters" #508.
