He was originally a midfielder before national coach Clemens Westerhof converted him to play left back. His club career in Europe was largely unsuccessful, and Iroha was allocated to San Jose Clash in 1996. The next season he was traded to DC United, where he won the league title. After a move to Spanish side Elche CF in 1997, he moved to Watford in December 1998, playing 10 games for the Hertfordshire side. Unfortunately a problem with bunions forced him to the sidelines, and he retired in March 2000.
