藤田和之
In October 2003, Sapp returned to NJPW, taking part again of Inoki's MMA army along with Takayama, Kazuyuki Fujita, Shinsuke Nakamura and Minoru Suzuki to face Nakanishi, Nagata, Hiroshi Tanahashi, Hiroyoshi Tenzan and Seiji Sakaguchi. He followed by some team matches along with Nakamura and AJPW's Keiji Mutoh, but his main push would come in his singles career. On March 28, 2004, Sapp defeated Kensuke Sasaki to win the IWGP Heavyweight Championship, becoming the first (and only, to date) African-American to hold the title. After successfully defending the title against Shinsuke Nakamura on May 3 at "Nexess", Sapp forfeited the title due to having lost to Kazuyuki Fujita in a mixed martial arts fight.
