After a strong performance at the 2001 Confederations Cup, Ono moved to Feyenoord of the Dutch Eredivisie in 2001. In his first season, he helped Feyenoord win the 2002 UEFA Cup, making him the first Japanese in history to win a European trophy. However, a string of injuries kept him sidelined for long periods. After he missed the majority of 2004–05, the club sold him. His stint at the Rotterdam based club is highly rated and Dutch midfielder Wesley Sneijder said "Shinji Ono is the toughest opponent I've ever faced".
