Rude engaged in a promotional tour in Japan with the championship; WCW held a partnership with Japanese promotion New Japan Pro Wrestling (NJPW). Rude lost the championship briefly to NJPW wrestler Hiroshi Hase as part of this arrangement, regaining it after eight days to set up a loss to Sting. An angle in which Rude defeated Sting for the championship in another NJPW-organized bout was then set up. The finish was arranged to involve Rude illegally using the title belt as a weapon to score the victory, causing officials to declare the win null and void. Sting refused to accept the title without "winning" it back. This match caused a back injury to Rude, which ended his in-ring career.
