Voodoo Murders
At All Japan's New Year's Shining Series show on January 3, 2008, Suwama saved Keiji Mutoh and Joe Doering from a post-match attack by the Voodoo Murders stable. After Suwama tore off his Voodoo Murders shirt, he shook hands with Mutoh and signaled his return to the All Japan Seikigun. On March 1, 2008, Suwama defeated Taru at Pro Wrestling Love in Ryogoku, Vol. 4. From April 5–9, Suwama participated in All Japan's annual Champion Carnival tournament, which he ultimately won on April 9 by defeating New Japan Pro-Wrestling (NJPW) star Hiroshi Tanahashi in the finals. Suwama finished the Carnival group stage with 2 wins, 1 loss and 1 draw, which earned him 5 points.
