Prior to being casted as Tsukino Usagi in Sailormoon, Miyuu was pursuing an idol career and appeared in several idol magazines and two idol DVDs. The magazines she appeared in included Pure Pure, BOMB, and memew. The DVDs she released are titled 「ME」 and 「YOU」 (The DVDs have since been released in a box set together, which is available on YesAsia for $82.49 USD). She was also on the television series Kids War 5 in the role of Youko Kimura.
On Pretty Guardian Sailormoon:
Miyuu was excited to audition for Pretty Guardian Sailormoon because she was a fan of the anime since kindergarten. According to Miyuu, she wanted the role so bad that when her audition group was through and one of the casting members asked them if there was anything anyone would like to add, she raised her hand and blurted out "I want to be Sailormoon!" Later she reflected that her action may have helped her get the role since it was a very Usagi-like action. 
In November of 2003 she was featured in another issue of BOMB magazine with Kitagawa Keiko and Hama Chisaki in costume to promote Sailormoon. After this appearance and another in Sabra magazine, she signed an exclusive modeling contract with Love Berry, a magazine that gives fashion advice to pre-teens.
Projects following PGSM:
In 2005, Miyuu released a third idol DVD Asian Kiss, which had an idol photo book of the same name. That same year she also released several more DVDs, South Wind, Perfect Collection, and Me→You. In 2006, she released Snow White and Fresh : Re : Fresh
Aside from the DVDs, Miyuu has also been busy working in both traditional acting and voice acting. She did her first major motion picture role in the horror film, Chain 2. She also has done a handful of commercials for a variety of products (from Tokyo Disney Sea to Nintendo DS -you can view these CMs on YouTube). In voice acting, Miyuu has played the role of Noah in the Fullmetal Alchemist: Conqueror of Shamballa movie and had a role in an episode of Black Cat.
