Nakazawa Yuko was one of five runners-up in a 1997 talent contest for a new Japanese rock idol.
After the contest, musician and producer Tsunku offered Nakazawa and the four other runners-up
（Abe Natsumi, Iida Kaori, Ishiguro Aya, and Fukuda Asuka） the chance to be taken under his wing
under one condition: they must sell 50,000 CDs of their debut song "Ai no Tane （Seed of Love）"
with five days of live promotion.
The quintet accomplished that task in four and thus Morning Musume was born.
On January 26, 1998, Morning Musume released their first official single, "Morning Coffee".
In August 1998, shortly after Morning Musume's formation, Nakazawa began a solo career, beginning with enka styled songs.
On December 31, 1998, Morning Musume received the Best New Artist Award from the 40th Japan Record Awards.
They also made their first annual appearance on the New Year's Eve music show Kohaku Uta Gassen as members of the red team.
Nakazawa held the role of the group's leader until her graduation on April 15, 2001.
Since then, Nakazawa has done some work in Japanese dramas , performed in various plays, and continued in her solo singing career
at a steady pace with reasonable success.
It was announced on October 19, 2008 by Hello! Project that Nakazawa, along with the rest of Elder Club will graduate
from Hello! Project on March 31, 2009.
On February 1, 2009, during the "Hello!Project Award 2009 ～Elder Club Graduation Special～" concert held at Yokohama Arena,
Nakazawa passed on her leadership position in Hello! Project to Takahashi Ai of Morning Musume.
In 2010, It was announced Nakazawa Yuko will be joining the new group, "Dream Morning Musume"
alongside other former-Morning Musume members.
