On June 10, 2004, Hiroko made her WWE debut as the geisha valet and translator for Kenzo Suzuki on the SmackDown! brand.
In November 2004, Hiroko began feuding with Torrie Wilson and numerous catfights took place between the two female wrestlers and Hiroko even wanted to fight her in a bra and panties match. The bra and panties match Hiroko wanted was later changed to a kimono match. In December 2004, backstage during a photo shoot, Torrie Wilson was given a bouquet of flowers from Kenzo. This angered Hiroko and she stripped Torrie to her underwear; this made Torrie chase, and eventually catch, Hiroko and strip her to her underwear as well. On an episode of SmackDown! held in Japan airing February 10, 2005, The kimono match was then held. Hiroko lost and was stripped to her bra and panties during the match. Hiroko and Kenzo were traded to the Raw brand on June 30, 2005, at the end of the 2005 Draft Lottery. However, they were both released by the WWE on July 6, 2005 without ever appearing on Raw.
