Kohei Sato
Tajiri's return to Japan came at Hustle on March 5, 2006 defeating Kohei Sato, The Monster PTA and Yoji Anjo with Razor Ramon Hard Gay and Shinjiro Otani. In the Hustle promotion, he was originally aligned with the babyface Hustle Army, a group which defends the sport of professional wrestling against the Monster Army (led by Monster General and Monster K, who aim to destroy the sport). However, he was hypnotized by Yinling into joining the Monster Army. In 2006, Tajiri took Yujiro Kushida under his wing and trained him while at Hustle. They participated in multiple tag team matches and tag team tournaments, and they also had several matches against one another. He also participated in Hustle GP, Hustle's only tournament, but was knocked out of the tournaments in the first round by Wataru Sakata. In his last appearance at Hustle, Tajiri defeated Muscle Sakai in a two out of three falls match which Tajiri won two to one.
