Been meaning to get to this for a while: Koichi Hori of the Chiba Lotte Marines retired back in December. There was supposed to be a retirement game for him a few weeks ago, but it got postponed by the earthquake (I think).
Hori was drafted by Lotte in 1987 when they were still the Orions. If I'm not mistaken, he was the last Lotte Orion still active (and the last former teammate of Choji Murata). Hori made the All Star team twice in his career (1995-96) and was named to one Best 9 team (2005) (which cover the three years in his career that he hit over .300). He appeared in one Nippon Series in 2005 when the Marines defeated the Tigers.
Hori's been around so long that his first hit and his first home run were against teams (Kintetsu Buffaloes and Orix Braves) that either don't exist or don't go by that name any more in stadiums (Kawasaki and Nishinomiya) that are no longer used.
Here's some cards:
I am fairly confident that this 1990 Takara card is his rookie card. This is definitely his first Takara card and I haven't found any Calbee cards for him from 1988-90:
