The Backflip Home Run
Koji Akiyama was famous for performing backflips at home plate after home runs - one of NPB's most iconic celebrations. Joining Seibu as an undrafted 1981 signee, he became a core outfielder from 1986. Career totals: 2,189 games, .270 average, 437 home runs, 1,312 RBIs. The 437 home runs rank among NPB's all-time leaders, complemented by speed and arm strength. His 303 career stolen bases combined power and speed.
Seibu Golden Era Core
Akiyama anchored Seibu's 1980s-90s golden era. Seven consecutive pennants from 1986-1992 included 6 Japan Series titles. Batting 3rd alongside Kazuhiro Kiyohara and Destrade, he formed a devastating cleanup. His 1987 season featured 43 home runs for the title. Eleven Golden Glove awards established his outfield defensive mastery. Like MLB's Ken Griffey Jr., Akiyama was a five-tool player excelling in hitting, defense, and baserunning.

Second Chapter with Daiei
Akiyama was traded to Daiei in 1994. Eight Daiei seasons included contributing to the 1999 championship. As veteran role model, he supported Matsunaka and Iguchi's development. Akiyama states he learned winning at Seibu and taught winning at Daiei. He retired at 40 in 2002 after 22 career seasons.
Championship as Manager
Akiyama managed SoftBank from 2009-2014, winning the 2011 Japan Series. He uniquely experienced championships as both player and manager. His managerial style emphasized player autonomy. Under chairman Oh, he maintained Hawks' winning culture, bridging to successor Kudo. Koji Akiyama experienced golden eras with both Seibu and Hawks - extraordinarily rare in NPB history.
