In late 1994, Hakushi joined the World Wrestling Federation (WWF). He debuted sporting Buddhist shakyo written all over his skin. He was also accompanied by a facepaint-wearing cultist named Shinja. Initially a heel, his first few matches were highlighted by victories over jobbers which included future star Matt Hardy and midcarders like Aldo Montoya, and 1-2-3 Kid.
Hakushi had a brief alliance with ninja wrestler Kwang, calling themselves collectively "Shogun", but after losing a tag team match due to his fault, Hakushi turned on him and defeated Kwang in the character's last appearance. Hakushi then feuded with former WWF Champion Bret Hart, wrestling a number of competitive matches against him. He also participated in a three-way feud with perennial jobber Barry Horowitz and Bodydonna Skip. Horowitz, who lost for years on WWF programming to get over new talent, surprisingly used his three-quarter nelson to secure a victory over Skip. Hakushi would also fall to Horowitz soon after because of interference from Skip. Hakushi and Horowitz would briefly form a tag team, leading to a face turn for Hakushi. At Survivor Series, Hakushi was a member of The Underdogs team, but was eliminated after a kick from his enemy 1-2-3 Kid. He also was a competitor in the 1996 Royal Rumble, where he was eliminated by Bret Hart's brother, Owen Hart.
During a match on Raw against Justin "Hawk" Bradshaw on the March 6, 1996 episode, Hakushi was hit by Bradshaw's branding iron after a loss. That week on WWF Superstars, commentator Jim Ross reported that he had been so humiliated by the branding that he left the WWF.
