Satoshi Ishii
After almost 6 years away from the ring, Fujita returned to professional wrestling in 2011 with his longtime associate and mentor Antonio Inoki's Inoki Genome Federation (IGF) promotion where he competed for the next few years. He won the IGF Championship from Jerome Le Banner in early 2012, and made successful defences against Bobby Lashley, Hideki Suzuki, Erik Hammer and Atsushi Sawada before dropping it to Satoshi Ishii in a worked shoot fight in December 2013. Fujita made a rare appearance outside of IGF in November 2015, competing for Genichiro Tenryu's Tenryu Project retirement show, where he teamed with Daisuke Sekimoto in a loss to Suwama and Yuji Okabayashi. Not long after this, Fujita left IGF and became inactive in pro wrestling once again.
