Han was the Most Valuable Player of the 1988 KBO League All Star Game. He won the KBO League batting title in 1990, with an average of .335. That year he finished second in the league in runs, hits, RBI, and walks.
Over his career, Han won eight KBO League Golden Glove Awards — mostly as a member of the Haitai Tigers — the most of any third baseman. His teams won the Korean Series six teams — five times with the Tigers and once with the Twins.
After retiring as a player, Han went on to be a coach for the Samsung Lions from 2003 to 2009. He managed the Hanwha Eagles from 2010 to 2012, but the team never finished higher than sixth-place during his tenure. Han returned to the Kia Tigers as a coach from 2013 to 2014.
