World Japan was ultimately viewed by Japanese fans as just another independent promotion in the saturated world of pro wrestling, so it wasn't able to make a dent in the major promotions' fanbases. Despite having tournaments to crown WMG (World Magma Greatest) champions in both the singles heavyweight and tag team divisions, these events didn't draw much interest. Eventually, the major talent (Sasaki, Tenryu, Koshinaka, Omori), went back to the major leagues, while World Japan continued operating on a part-time basis as Riki Chōshū's exclusive show. In December 2004, however, Chōshū himself appeared again on a New Japan card, indicating that his days of promoting World Japan had come to an end.
The failure of World Japan has put a strain on some relationships, especially the one with Kensuke Sasaki and Riki Chōshū. So much to the point when Chōshū returned to NJPW, Sasaki abruptly left, refusing to work with Chōshū at all, because of the problems the two developed over financial issues.
