I was very excited when the Orioles signed him from Japan because of my Japanese heritage. My Grandmother on my mother's side of the family was from Japan.
Here's a few of my favorite Koji cards. I kind of have a PC of him, meaning when I see cards of him I pick them up but don't go out of my way looking for them. (LMK if you have any you may have for trade) Topps seemed to recycle the living crap out of the same few photos of Koji so there aren't that many "different" cards of him:
These 2 came through the mail during spring training this year. He was an awesome TTM'er while in Baltimore.
Rangers fans, I know you are going to enjoy watching Koji pitch.
Best of Luck to you in Texas, Koji!
