He was trained by Último Dragón and graduated from Dragon's "Toryumon Gym" in 1997, making his professional wrestling debut on May 11, 1997 by defeating fellow débutante Nobuhiko Oshima.

He used to dance his way to the ring, wearing elaborate costumes and eye-masks, and stripped from them before the matches, sometimes with women in the crowd actually stuffing money into his tights.

[5] Less than a year into his professional career, he gained some mainstream notoriety in North America with World Championship Wrestling in early and mid-1998.

The program came to a head when his interference backfired in a tag team match between The Dancing Fools and The Public Enemy at the 1998 Road Wild pay-per-view.

Two nights later on the August 10 episode of Nitro, he was told by Wright and Disco Inferno that if he wanted to be a member of The Dancing Fools, he needed to impress them in a match against Eddie Guerrero.

During those two months, he appeared sporadically in squash matches and as a participant in the annual World War 3 battle royal on November 22, 1998.

During his early years in Toryumon he would align himself with wrestlers such as Dragon Kid and Kenichiro Arai to combat the factions of Crazy MAX and M2K.

On October 28, Magnum dissolved M2K and announced that he and the remnants of M2K were the real Do FIXER, and that Darkness Dragon – now renamed K-ness – was still a member of the group and was sent into the home army (Seikigun) to cause problems within it.

On November 20, 2008, Magnum returned to professional wrestling, appearing under a new gimmick, Detective Alan Kuroki, at a Hustle event in Tokyo, Japan.
