In April 2004, he created the GHC Openweight Hardcore Championship to get back into singles competitions, and adapting an attitude manifested by wearing trunks that were odd colors for him. These motives helped put him back into contention for the GHC title against Kenta Kobashi, which was voted as Match of the Year. Late 2004 and much of 2005 were highlighted by his feud with protégé Makoto Hashi where Akiyama used "tough love" to toughen up young Hashi. On January 22, 2006, Akiyama defeated Akira Taue to become the GHC Heavyweight Champion for the second time, defending the title against Minoru Suzuki on March 5 and Masao Inoue on April 24. Akiyama was defeated by Naomichi Marufuji on Noah's September 9 Nippon Budokan show in his third defense of the GHC Heavyweight Title.
