Career
She is most famous for her participation in Japanese popular girl group Morning Musume
Aya Ishiguro was a runner-up in a 1997 contest to find a new female rock idol. Tsunku promised to take the quintet under his wing if they sold 50,000 copies of their debut single "Ai no Tane" within five days. During Ishiguro"s years in Morning Musume, she was given mostly harmony lines due to her low singing voice, which was used to support the voices of others
However, in late 1998 Tsunku decided to create first sub-group Tanpopo, a subgroup of Morning Musume (by then consisting of eight members) that included Ishiguro, Iida and second generation member Mari Yaguchi.
Tanpopo"s songs were slower and more mature than the majority of Morning Musume"s, which allowed Ishiguro"s voice to shine through. After seven singles and three albums with Morning Musume, and four singles and one album with Tanpopo, Ishiguro left both groups and Hello! Project in January 2000, shortly after the release of the single "Love Machine" in September 1999.
Ishiguro has published a book about her transition from Morning Musume to motherhood in 2003 called Musume Kara Mama e-Ishiguro Aya no LOVE2 Ko Sodate Revolution.She released a follow-up book in 2004 called Ko Sodate Project!
