Editor's note: Looking back at one of the greatest upsets in sports history, The Japan Times is featuring a series of stories over the next several days to commemorate the 25th anniversary of the Mike Tyson-James "Buster" Douglas fight on Feb. 11, 1990, at Tokyo Dome.

Lennox Lewis' global ascent as a premier boxer truly began less than two years before James "Buster" Douglas shocked the world on Feb. 11, 1990, at Tokyo Dome and knocked out previously unbeaten world heavyweight champion Mike Tyson in the 10th round.

Lewis grabbed the super heavyweight gold medal at the 1988 Seoul Olympics.
