<Maki Goto's profile(from Wikipedia)>

Maki Goto (Gotō Maki?, born September 23, 1985 in Edogawa, Tokyo, Japan) is a J-pop singer currently signed to the sublabel Rhythm Zone.
Before joining Avex, she was a soloist of Hello! Project and member of Morning Musume.
She has performed in numerous Hello! Project subgroups such as Petitmoni, Akagumi 4, 7-nin Matsuri, Gomattou and Nochiura Natsumi.

In 1999, Maki Goto was selected as the only member for the 3rd generation of Morning Musume.
Their first single after Goto joined, "Love Machine" sold over a million copies, over nine times the amount of copies they had sold for their previous single.
During her time in Morning Musume she was one of the founding members of Pucchi Moni and she started a solo singing career in 2001 with the single.
Until her graduation from Morning Musume she was one of the leading vocalists in most of the songs released.
Post-graduation she has mostly concentrated on her solo career and occasionally on limited time Hello! Project units such as Gomattou, Nochiura Natsumi, and DEF.DIVA.
As time has passed, she has increasingly concentrated on acting in addition to singing.
She has also performed at the Asia song festival 2005 in Pusan, Korea to represent Japan.

In early 2007, Goto was chosen to be a member of Morning Musume Tanjō 10 Nen Kinentai —a unit created to celebrate Morning Musume's 10th anniversary as a group.
Morning Musume Tanjō 10 Nen Kinentai also consists of Natsumi Abe, Kaori Iida, Risa Niigaki and Koharu Kusumi.
Their single, Bokura ga Ikiru My Asia, was released on January 24, 2007.
