In what I think was the first signing of a former NPB player this off season, the Cleveland Indians last week announced the signing of former Yokohama DENA Baystars ikusei pitcher Kota Kobayashi. Kobayashi was drafted out of high school by Yokohama in the 2010 draft (which took place in October of 2009). He spent all three season with Yokohama in the minors.
Kobayashi doesn't have a whole lot of baseball cards. Like most of the rest of his draft class, he appeared in the 2010 BBM Rookie Edition set. His only other cards were in the annual BBM Baystars team sets - he never appeared in any of the main "flagship" sets from BBM, Calbee, Konami or Bandai. Here's his Rookie Edition card (#049):
I also want to note that Kobayashi is the second Japanese player that the Indians signed this off season (although the first former member of an NPB team). Back in October, they signed Takuya Tsuchida from Hagura High School. Tsuchida went undrafted in the NPB draft in October and signed a deal with the Indians shortly after. There are the same amount of legitimate cards of Tsuchida kicking around as there are for Shohei Otani.
