佐々木健介
On March 1, 2009, Akiyama defeated Kensuke Sasaki for the GHC Heavyweight Championship. On June 14, 2009, he was forced to vacate the title due to injury, in which left him out of action for the rest of the tour. After making his return later that year, Akiyama continued to wrestle sporadically whilst struggling with back injuries and the burden of post traumatic stress syndrome, following the death of Mitsuharu Misawa.
