Ricky Fuji
Onita lost the Brass Knuckles Heavyweight Championship to Grigory Verichev on February 27, 1991. Onita unsuccessfully challenged Verichev for the title in a rematch on May 5 and then received another title shot on May 29, where Onita defeated Verichev to regain the renamed World Martial Arts Heavyweight Championship. On August 17, Onita defeated Jimmy Backlund, Ricky Fuji and Sambo Asako to win the Barbed Wire Deathmatch Tournament. During this time, Mr. Pogo left FMW and Tarzan Goto turned on Onita once again to renew their feud and became Onita's arch rival. Onita defeated Goto in the first-ever no rope exploding barbed wire steel cage deathmatch at the very successful 2nd Anniversary Show on September 23 at the Kawasaki Stadium in Kawasaki, which would become the venue for FMW's major events in future.
