東京愚連隊
In 2002, Gentaro began working for the newly founded World Entertainment Wrestling (WEW), teaming with Takashi Sasaki on August 23 to defeat Hi68 and Taka Michinoku and become the first WEW-promoted World Tag Team Champions. After a seven-month reign, Gentaro and Sasaki lost the title to Kintaro Kanemura and Tetsuhiro Kuroda on March 11, 2003. The following year, WEW folded and was replaced by Apache Pro-Wrestling Army, with Gentaro jumping to the new promotion, where he would join the Apache Army. As a member of the Apache Army, Gentaro formed a regular partnership with The Winger and adopted a new character, opposing all hardcore wrestling. On September 23, 2007, Gentaro and The Winger defeated Jun Kasai and Jaki Numazawa to win the WEW World Tag Team Championship, starting Gentaro's second reign with the title. They would lose the title to Tokyo Gurentai (Mazada and Nosawa Rongai) on April 17, 2008. The following year, Apache Pro-Wrestling Army folded.
