Saburo Ohmura of the Marines announced his retirement back on September 1st.  He was drafted out of PL Gakuen High School in the first round of the fall 1994 draft by Lotte.  He registered his name as "Saburo" since there was another player with the Marines with the same last name (Iwao Ohmura) and he continued to go by his first name even after the other Ohmura retired.

He has two rookie cards in the 1995 BBM set - #571 in the regular set and #644 in the Late Series.  His first Calbee card is #152 in the 2002 set.  The only one of these I have is the Late Series card:

1995 BBM Late Series #644

Saburo played for the Marines for almost his entire career.  He was traded to the Giants in the middle of the 2011 season and spent the remainder of the season with them (and changed his registered name to "Saburo Ohmura").  He returned to Lotte that winter however and spent the rest of his career in Chiba.

His best season was probably 2009 when he hit .314 with 22 home runs.  He made the All Star team twice (2002 & 2009) and won two Golden Glove awards (2005 & 2007).  He played in two Nippon Series (in 2005 and 2010, on the victorious side both times) and won an "Outstanding Player" award in the 2005 Series.
