Ichiro

Why do all the baseball cards for Ichiro Suzuki have his first name listed and not his last? His jersey even only lists his first name, which from what I can find had to be approve by the commissioner. I don't know of any other players that is allow to use their first name only on jerseys and cards, of course I know 2% of the entire knowledge of baseball. I guess his popularity from Japan and everyone calling him Ichiro only just came over with him. In any case it is a bit odd. If you know something, let us know thanks.
