Kei Yasuda

On May 29, 2013, Yasuda announced that she had married chef Kozaki Yoichi. On July 27, 2017, she has announced that she is pregnant with her first baby.

In 2010, it was announced that Kei Yasuda would be joining other former-Morning Musume members for the new group "Dream Morning Musume."

Yasuda graduated from Hello! Project on March 31, 2009, along with the rest of the H!P Elder Club.

During a promotional appearance on Utaban in 2004, Yasuda revealed that she has been learning how to play the flute.

Yasuda left in mid-2003 at the same time when Morning Musume's 6th generation became full-fledged members. Tsunku commented that this one-time sixteen-member formation will be the largest Morning Musume. During her good-bye concert, Yasuda sang a remixed rock version of "Never Forget," which was also Fukuda's good-bye song. Additionally, as a special gift, Tsunku gave Yasuda a CD of her own solo version of "As for One Day," her last single with Morning Musume.

After Morning Musume's then-leader Yuko Nakazawa left in 2001, Yasuda (who was the oldest member of the group at the time) became a co-leader along with Kaori Iida.

Yasuda and Ichii sang a particularly catchy duet known as "Otome no Shinrigaku" (Girl's Psychology) on Morning Musume's second album. In response to the popularity, Tsunku decided to group them together with the third generation member, Maki Goto to create the Morning Musume subgroup Petitmoni (also known as Pucchimoni) in 1999. Their first single, "Chokotto Love," sold over a million copies.

Yasuda attended Kimitsu Shogyo (Commercial) High School in Futtsu City, Chiba Prefecture, but dropped out to pursue her dreams in the entertainment industry. She worked in a McDonald's restaurant in her hometown, until 1998.
