Masao Inoue
After leaving sumo he was soon scouted by All Japan Pro Wrestling. After training in their dojo, he made his debut in 2000 in a tag team match in which he partnered Masao Inoue against Takeshi Morishima and Jun Akiyama. However, before he could build any momentum, Mitsuharu Misawa left AJPW and in the process, took most of the native talent with Rikio being among these talents. In Pro Wrestling Noah, he has seen much success. He dethroned the legendary Kenta Kobashi for the GHC Heavyweight Championship (at the end of this match Rikio can be seen sobbing as he accepts the title from Kobashi), ending his two-year reign, before losing the title to Akira Taue some time later. On June 4, 2006, he captured his second GHC Tag Team Championship with Jun Akiyama when he pinned Muhammad Yone after a Musou. However, Rikio and Akiyama were forced to vacate their title on September 25, 2006 after Rikio suffered a neck injury.
