CAGE FORCE
In 2007, Yoshida was entered into a Cage Force welterweight tournament sponsored by the Worldwide Cage Network. In the opening round of the tournament, Yoshida defeated two-time interim Pancrase champion Katsuya Inoue by knockout. He went on to defeat Matt Cain in the quarterfinals and former Shooto champion Akira Kikuchi in the semi-finals of the tournament. In the finals, Yoshida defeated Dan Hardy by disqualification after being struck by a kick to the groin, becoming the first Cage Force welterweight tournament winner.
