Pride

Shoji had his worldwide debut taking on Renzo Gracie from the Gracie family at the first event of Pride in 1997. Though clearly outclassed, Shoji held his own and escaped from numerous submission attempts through the match, including an armbar and an omoplata which were almost fully locked, while regularly landing low kicks and some knees to the head. After thirty minutes, the match was ruled a draw due to the absence of judges. Nonetheless, Shoji got acclaimed by the crowd for his performance, which included grabbing the mic after the match and yelling "What do you say now, Gracies? Who said the Japanese were the weakest?" (Nani ga Gracie jā! Nani ga Nippon sai jaku jā?)

He returned at the next two events of Pride, submitting Juan Mott via rear naked choke and drawing with Takada Dojo understudy and fellow underdog Daijiro Matsui. However, his biggest victory came at Pride 4, where Shoji faced another unbeaten Brazilian jiu-jitsu exponent, Wallid Ismail. The Brazilian was aggressive and held Akira mounted for the first round, with Shoji reversing him every time. At the second round, however, the Japanese got the upper hand over a tired Ismail and landed multiple answered punches, which prompted the referee to stop the match for a win for Shoji.

Akira next faced Ukrainian Igor Vovchanchyn, who would become one of Pride's top strikers. Knowing the strengths of his adversary, Shoji played conservatively and avoided the KO for a decision loss. Shortly after, Shoji bounced back with another shocking victory in a match against Ultimate Fighting Championship champion and former King of Pancrase Guy Mezger. The fight was slow and strategic, with long battles on the clinch, with Mezger landing several strikes, but Shoji eventually found opportunities to take Mezger down and perform ground and pound. The judges gave the split decision to the Japanese, which was met with controversy in the United States.^[2]

At the Pride Grand Prix 2000 tournament, Shoji was first pitted against luta livre practitioner Ebenezer Fontes Braga, getting a unanimous decision victory. He advanced round, but he was then eliminated by the eventual winner Mark Coleman.

Shoji's last match in Pride would be in its very last event in 2007, fighting Gilbert Yvel and losing by TKO after a brief grappling exchange.

Retirement

While working as a fighting referee in Dream, Shoji considered a final retirement match.^[1] He got his will at DEEP 53 in a match against Kazuo Misaki, which he lost by TKO in the second round. Both Misaki and Shoji broke out in tears after the fight, overwhelmed by emotions, knowing it was Shoji's final match.
