Onryo gained popularity and began appearing in promotions like Pro Wrestling Fujiwara Gumi, Wrestle Association R and Dramatic Dream Team before eventually signing with Frontier Martial Arts Wrestling (FMW) in 2000. He also participated in that year's Super J-Cup, eliminating Curry Man before being eliminated himself by Cima. His FMW tenure would be the most prolific one, however. He participated in a feud with Goemon about a cursed championship that slowly killed his champion, which was revealed as the reason why Onryo became a ghost in the past.
